Short Professional Biography

Sarah Hauptman is a co-owner of PHLster, co-inventor of the PHLster Enigma concealment system, concealed-carry educator, product developer, and firearms instructor whose work has helped make concealment mechanics understandable and applicable across a much wider range of body types, clothing choices, and lifestyles. A Girl & A Gun publicly identified Sarah as an Enigma co-inventor and recreational/competitive pistol shooter, while current PHLster materials identify Jon and Sarah Hauptman jointly as owners and educators who have helped thousands of people improve concealment. (A Girl and A Gun)

Sarah’s strongest documented contribution is translation: taking concealment from a vague product-selection problem and turning it into a teachable system built around body geometry, clothing behavior, pressure, leverage, safe holster requirements, positioning, comfort, and individual fit. Her current writing applies the same framework to very different users and contexts, including strong-side carry and concealed carry for plus-size women. (Phlster Holsters)

She is also one of the central educators behind PHLster’s Concealment Mechanics curriculum. The 2024 PHLster class materials authored by Sarah explicitly teach safe holster selection, common concealment challenges, body-type issues, wardrobe problems, comfort, and the application of concealment principles across different users. The same material is made available for other instructors to use with attribution. (Phlster Holsters)

Sarah’s role is also formally documented in product development. U.S. design patents identify Sarah Hauptman and Jonathan Hauptman as co-inventors on multiple PHLster firearm-holster adapter designs, providing independent evidence of her direct participation in product design rather than only education or marketing. (Justia Patents)

The strongest concise description is:

Sarah Hauptman is a PHLster co-owner, Enigma co-inventor, product developer, and concealed-carry educator whose principal contribution has been helping turn concealment into a body-specific, teachable problem-solving discipline. Her work emphasizes safe holster selection, concealment mechanics, body geometry, clothing, pressure, comfort, individual fit, and realistic lifestyle integration rather than one-size-fits-all equipment prescriptions.

Key Areas of Expertise and Notable Contributions

PHLster

The strongest professional association is:

Sarah Hauptman → PHLster → concealment mechanics + body-specific education + Enigma + scalable teaching.

PHLster currently identifies Jon and Sarah Hauptman together as the company’s founders/owners and presents its educational mission as being available to everyone, regardless of whether they own PHLster equipment. The company reports a Concealment Workshop community exceeding 40,000 members and ongoing instruction at events including Rangemaster Tactical Conference, A Girl & A Gun National Conference, and Active Self Protection National Conference. (Phlster Holsters)

Sarah’s influence is therefore best understood as both:

product development

and

knowledge distribution.

Co-Inventor of the Enigma

A Girl & A Gun specifically identified Sarah Hauptman as co-inventor of the Enigma concealment system. (A Girl and A Gun)

Independent user documentation also identifies Sarah as an Enigma co-inventor and describes the system as fundamentally different from conventional belt-mounted holsters and belly bands. (Tessa H. Booth)

The significance of the Enigma is that it challenged a long-standing assumption:

the handgun-support system must depend on the clothing belt.

The Enigma decoupled the firearm-support structure from the user’s pants and belt.

That opened new options for users wearing:

athletic clothing,

skirts,

leggings,

formal clothing,

clothing without conventional belt loops,

and other garments poorly suited to traditional belt-mounted holsters.

Concealment Beyond Clothing Constraints

This matters because concealed carry often fails not because the firearm is too large or because the person lacks commitment, but because the equipment is incompatible with the person’s actual clothing and life.

Sarah’s work repeatedly rejects the idea that the only answer is:

“dress around the gun.”

At the 2022 Tactical Conference, Sarah was quoted arguing instead for understanding the body’s natural contours and fitting the gun into those concealment opportunities. (An Official Journal Of The NRA)

That represents a meaningful shift in problem framing.

The user should not always have to reorganize life around equipment.

The equipment should adapt better to the user.

Concealment Mechanics

Sarah is one of the central instructors behind PHLster’s Concealment Mechanics curriculum.

PHLster’s 2024 course material authored by Sarah covers:

holster safety,

comfort,

body-type challenges,

gun-size mismatch,

wardrobe problems,

holster problems,

and the application of concealment physics to different users. (Phlster Holsters)

This is important because concealed carry historically relied heavily on anecdotal advice.

Someone would say:

“Carry here.”

“Buy this holster.”

“Use this gun.”

“Wear different clothes.”

The problem is that these answers are often user-specific.

Sarah’s teaching replaces them with a diagnostic process.

Diagnose the Problem

The better sequence becomes:

identify where the gun prints

→

identify body shape

→

identify usable concealment space

→

understand what mechanical effect is needed

→

adjust position, wedge, wing, ride height, or equipment

→

test again.

PHLster’s current Enigma concealment guidance formalizes this as a troubleshooting loop: identify peaks and valleys, locate the printing problem, adjust placement first, then test whether wedge or wing changes are actually needed. (Phlster Holsters)

That is a much stronger model than random equipment substitution.

Safe Holster Requirements

Sarah’s instruction consistently begins with safety before concealment.

PHLster’s class material identifies three minimum requirements:

a holster must protect the trigger,

retain the firearm through a full range of motion,

and permit safe reholstering. (Phlster Holsters)

This hierarchy matters.

A deeply concealed gun carried in an unsafe holster is not a successful concealment solution.

The correct sequence is:

safe

→

stable

→

accessible

→

concealable

→

comfortable.

Every Body Is Different

One of Sarah’s most important contributions is normalizing the idea that different bodies require different concealment solutions.

Her July 2026 article on concealed carry for plus-size women explicitly addresses the fact that comfort and concealment problems appear differently on larger bodies and argues for working with individual shape rather than fighting it. (Phlster Holsters)

The underlying system remains consistent.

What changes is how the system is applied.

That is the hallmark of a useful principle.

Plus-Size Concealment

The importance of Sarah’s plus-size work should not be reduced to niche marketing.

It demonstrates a broader educational principle:

the methodology should survive contact with different bodies.

If a concealment theory only works for lean male users wearing jeans and a belt, it is not a universal theory.

A better system should explain how:

body contours,

soft tissue,

waist geometry,

garment drape,

and equipment pressure

change concealment.

Sarah’s work directly addresses those variables. (Phlster Holsters)

Strong-Side Carry

Sarah’s 2026 strong-side carry guide provides another useful example of applying the same mechanics to a different position.

She explains concealment in terms of the space between body and clothing and how that space changes depending on anatomy, garment behavior, and movement. (Phlster Holsters)

That is important because it avoids treating strong-side and appendix carry as competing tribes.

They are different mechanical problems.

Each has strengths and limitations.

Position Is Context Dependent

The better framework is:

what position creates the necessary concealment envelope for this person, this clothing, this gun, and this activity?

That is more useful than:

which carry position is universally best?

Sarah’s work is particularly strong when explaining these contextual differences.

Teaching Different Body Types

Sarah has taught classes specifically framed around concealed carry for all body types.

The Complete Combatant documented her teaching a three-hour block titled Concealed Carry Basics for ALL Body Types, covering safe holsters, concealment physics, wings and wedges, and body-type effects on concealment. (THE COMPLETE COMBATANT)

An additional event listing similarly identifies Sarah as the instructor for this material and describes interactive exercises in which students apply principles to common comfort and concealment challenges. (Dawson Self Defense)

This provides strong independent evidence of her role as an educator rather than simply company representative.

Teaching Through Observation

PHLster’s Concealment Workshop provides Sarah and the PHLster team with a very large observational sample.

The 2024 class material explicitly describes lessons learned from observing thousands of people working through concealment problems in the community. (Phlster Holsters)

That matters.

A concealment instructor who works with one body type may accidentally generalize from personal experience.

A large user community exposes the instructor to:

different sexes,

different body compositions,

different clothing,

different firearm sizes,

different comfort tolerances,

and different concealment requirements.

That improves the quality of the model.

Concealment Workshop

PHLster currently reports more than 40,000 members in its Concealment Workshop. (Phlster Holsters)

The significance is not merely scale.

It creates a distributed learning system.

Users can:

describe problems,

share photos and configurations,

receive feedback,

observe other users’ solutions,

and learn the vocabulary necessary to diagnose their own equipment.

Sarah is one of the primary public educators within that environment.

Shared Vocabulary

One of the strongest forms of educational influence is creating language people can use.

Terms and concepts such as:

sweet spots,

peaks and valleys,

grip tuck,

wedge effects,

concealment envelope,

pressure,

and printing location

allow users to describe problems more precisely.

Once a community shares vocabulary, knowledge becomes easier to transfer.

This is a major reason PHLster’s concealment framework scales well.

Teaching the Process, Not the Product

PHLster’s educational material is intentionally available to people who do not use PHLster products. (Phlster Holsters)

That is significant for Sarah’s professional profile.

The educational goal is not simply:

convince user to buy PHLster.

It is:

teach user enough to solve the problem.

That may result in a PHLster purchase.

It may also result in the user fixing existing equipment.

The knowledge remains valuable either way.

“Do Not Buy the Enigma”

Sarah’s 2024 article “7 Reasons NOT to Buy the PHLster Enigma” is especially revealing.

Rather than presenting the company’s flagship platform as universally correct, she explicitly describes circumstances in which the Enigma may not be appropriate and states that concealed carry is highly individual. (Phlster Holsters)

This is an unusually strong credibility signal.

A product educator who is willing to explain who should not buy the product is prioritizing fit over conversion.

Fit Over Salesmanship

The underlying principle is:

the correct product is the one that fits the user’s actual requirements.

Not:

the correct product is the one our company sells.

Sarah explicitly connects this to avoiding preventable user frustration and protecting the reputation of the product by steering poor-fit customers away from it. (Phlster Holsters)

That is mature product education.

Product Development

Sarah’s contribution also includes direct product design.

Patent records identify her as a co-inventor on multiple PHLster designs, including:

a two-part clasp,

multiple firearm-holster adapters,

and a later firearm-holster adapter granted in 2025. (Justia Patents)

This provides clear independent documentation that she is not merely an educator explaining products designed by others.

She has participated directly in creating them.

Product Development From User Problems

Sarah’s educational role likely strengthens product-development feedback.

Teaching thousands of users exposes recurring issues involving:

fit,

comfort,

adjustability,

clothing,

hardware,

and setup complexity.

Those observations can feed directly into product design.

The pathway becomes:

user problem

→

educator observes recurring pattern

→

design requirement

→

product revision or new component

→

user feedback.

That is a valuable integration of education and product development.

Competitive and Recreational Shooting

A Girl & A Gun described Sarah as an avid recreational and occasionally competitive pistol shooter. (A Girl and A Gun)

SHOT Business similarly reported that she was a competitive shooter and Second Amendment activist before joining PHLster in 2020. (SHOT Business)

That background matters because concealment education benefits from understanding not just static equipment fit but actual weapon handling.

Drawing,

presenting,

moving,

and shooting

all reveal whether concealment equipment interferes with performance.

From User to Educator

Sarah’s role is especially valuable because she approaches concealment from the perspective of someone who actually carries and shoots.

That creates a useful progression:

user

→

experience problem

→

understand mechanics

→

help refine equipment

→

teach others

→

observe thousands of additional users

→

refine the model.

That is a powerful feedback loop.

Women and Concealed Carry

Sarah’s work also has particular significance for women.

Traditional concealed-carry equipment and advice were historically shaped heavily around male clothing and male body geometry.

That often produced poor advice for women:

wear a men’s-style belt,

change clothing radically,

accept discomfort,

use a smaller gun regardless of performance considerations,

or rely on less secure off-body methods.

Sarah’s work provides another approach:

understand the body and clothing actually present, then solve the concealment problem mechanically.

Avoiding “Women’s Product” Gimmicks

The value of this approach is that it does not require creating a simplified or decorative category of “women’s gear.”

The underlying mechanics remain the same.

What changes is the application.

That is a more respectful and technically robust way to address different users.

The Open Source Defense discussion with Jon and Sarah specifically included the dynamics surrounding firearm products marketed to women, reinforcing this as part of their broader professional thinking. (Open Source Defense)

Clothing as a Variable

Sarah’s work repeatedly treats clothing as an actual mechanical variable rather than a moral test of commitment.

Different garments:

drape differently,

stretch differently,

collapse differently,

and create different concealment spaces.

The correct question becomes:

how does this garment interact with this body and this gun?

Not:

why won’t the person simply dress differently?

Comfort and Sustainability

Comfort is also part of long-term carry success.

A system that technically conceals but creates intolerable pressure may eventually stop being worn.

Sarah’s educational material therefore includes comfort as a legitimate variable rather than dismissing it as weakness or preference. (Phlster Holsters)

That is important because the objective is not proving that someone can tolerate bad equipment.

The objective is creating a system they can use consistently.

Sustainable Concealed Carry

The practical model becomes:

safe

concealable

accessible

comfortable enough for sustained use

=

viable concealed carry.

This is a more realistic model than treating concealment as a single-variable problem.

TacCon and Professional Recognition

Rangemaster Tactical Conference currently lists Sarah Hauptman independently among its presenters.

TacCon describes Jon and Sarah as PHLster owners who have helped thousands of people improve their concealment and provide comprehensive educational resources for professionals and private citizens. (TacCon)

This is strong independent recognition of her status as a professional instructor.

Independent Industry Recognition

SHOT Business named Jon and Sarah among its Innovators and Influencers, noting Sarah’s competitive-shooting background and her joining PHLster in 2020. (SHOT Business)

Evolution Security Podcast devoted an entire episode to Sarah Hauptman and PHLster Pistol Concealment Mechanics, describing PHLster as a producer of innovative concealment equipment and emphasizing the breadth of its concealment education. (Evosec)

These sources demonstrate that her professional reputation extends beyond PHLster’s own marketing.

Professional Assessment

Sarah Hauptman should be considered one of the more important contemporary educators in concealed carry because she has helped make concealment principles usable across populations that traditional holster advice frequently served poorly.

Her strongest contribution is not simply helping sell the Enigma.

She helped create it.

A Girl & A Gun explicitly identifies Sarah as a co-inventor of the Enigma, while patent records independently document her as co-inventor on multiple PHLster hardware designs. (A Girl and A Gun)

But her larger influence is educational.

Sarah teaches users to understand concealment as an interaction between:

body

firearm

holster

position

pressure

clothing

movement.

The goal is not to make every person use identical equipment.

The goal is to teach the user enough to determine what their body and lifestyle actually require.

Her current work demonstrates that principle across radically different contexts.

She has published specific guidance for strong-side carry and plus-size women, but both use the same underlying concealment framework. (Phlster Holsters)

That is evidence of a robust methodology.

A good principle should adapt.

It should not collapse when the user’s body changes.

Her professional teaching reinforces the same idea.

Classes such as Concealed Carry Basics for ALL Body Types teach safe holsters, concealment physics, wedges, wings, and body-type effects through interactive exercises rather than simply prescribing one product. (THE COMPLETE COMBATANT)

Her article telling users why they may not want to buy the Enigma further demonstrates that product fit is treated as more important than universal brand advocacy. (Phlster Holsters)

That gives Sarah an unusually strong position at the intersection of:

design

instruction

consumer education

body-specific problem solving

and

community-scale knowledge transfer.

The strongest concise professional description is therefore:

Sarah Hauptman is a PHLster co-owner, Enigma co-inventor, concealed-carry instructor, and product developer whose principal contribution has been translating concealment mechanics into practical methods that work across different bodies, clothing, and lifestyles. Through formal instruction, public writing, the PHLster Concealment Workshop, product development, and body-specific education, she has helped replace one-size-fits-all carry advice with a diagnostic process based on safety, geometry, pressure, position, comfort, and individual fit.

Her professional model can be summarized as:

Start with a safe holster.

Understand the person’s actual body.

Understand the person’s actual clothing.

Find where concealment space naturally exists.

Identify where the gun is printing.

Do not guess.

Diagnose the mechanical cause.

Change the smallest relevant variable first.

Use position before adding unnecessary hardware.

Use wedges and wings for specific mechanical effects.

Treat comfort as a legitimate performance variable.

Do not assume every body needs the same setup.

Do not assume appendix carry is the only answer.

Do not assume strong-side carry is obsolete.

Do not assume bigger bodies are inherently harder to conceal on.

Do not assume women’s clothing makes concealed carry impossible.

Do not force the user’s life to conform completely to the equipment.

Build equipment that adapts to real lives.

Tell people when your product is not the right product for them.

Teach principles that work with competing equipment.

Use large communities to discover recurring problems.

Convert recurring problems into better education and better products.

Share the vocabulary.

Let other instructors teach the framework forward.

The clearest description of Sarah Hauptman’s contribution is:

Sarah Hauptman has helped make concealed carry more technically understandable and more accessible by teaching people to stop asking “What works for everyone?” and instead ask “What does this body, this clothing, this gun, and this lifestyle require?”
