Ryan Hamre is the founder and president of Hamre Forge, a Maine-based firearms-accessory manufacturer specializing in modern revolver stocks and grips produced through advanced additive-manufacturing methods.

Hamre Forge: https://www.hamreforge.com/

A longtime revolver shooter and enthusiast, Hamre founded Hamre Forge in 2023 after identifying shortcomings in many of the grip options available for compact defensive revolvers. His approximately two decades of professional experience as an infrastructure architect influenced an engineering-oriented approach centered on identifying requirements, prototyping solutions, testing them, incorporating user feedback, and improving production systems.

Hamre Forge initially used conventional fused-deposition 3D printing before transitioning to Selective Laser Sintering (SLS), also known as Powder Bed Fusion, using PA-12 nylon. The transition allowed Hamre to produce stronger and more dimensionally consistent parts while expanding production beyond what is normally associated with small-scale consumer 3D printing.

His work has included original Hamre Forge designs as well as modern production versions of classic Craig Spegel revolver-stock designs, connecting one of the best-known names in traditional custom revolver stocks with contemporary digital manufacturing.

Hamre Forge subsequently became an OEM/commercial supplier, including providing grips for the Lipsey’s Exclusive Ultimate Carry J-Frame project. Hamre has described the Lipsey’s opportunity as his company’s first major commercial deal.

His other notable work includes the Hamre Forge AFR UnderCover, developed in connection with the contemporary American Fighting Revolver concept, along with grip systems for Smith & Wesson J-, K-, L-, and N-frame revolvers, Ruger LCR/LCRx revolvers, Kimber revolvers, and other platforms.

Hamre is also an active participant in the contemporary firearms-training and revolver-development community. He has appeared on Primary & Secondary ModCast discussions addressing both 3D printing and the modernization of revolvers, connecting his manufacturing work with broader discussions about how older firearm platforms can benefit from modern materials, manufacturing, accessories, sights, ammunition, training, and carry methods.

Ryan Hamre’s professional contribution is best characterized as the intersection of:

traditional revolver knowledge + user-centered design + digital prototyping + additive manufacturing + modern defensive-firearms application.

Professional Profile

A Revolver Shooter Identifies a Problem

Hamre Forge began with a familiar product-development sequence:

user encounters problem
↓
available products do not completely solve it
↓
user develops his own solution.

Ryan Hamre was already a revolver enthusiast.

He carried revolvers.

He shot revolvers.

That practical experience exposed him to the compromises inherent in compact defensive-revolver grips.

A revolver grip needs to satisfy several competing requirements.

It should:

• provide adequate control;
• manage recoil;
• permit rapid access from concealment;
• avoid unnecessary printing under clothing;
• allow access to the cylinder release;
• accommodate reloads;
• fit different hand sizes;
• interface correctly with the frame;
• and remain durable.

Improving one characteristic can negatively affect another.

A larger grip may improve recoil management but become harder to conceal.

A smaller grip may disappear under clothing but reduce control.

Aggressive texture may improve shooting performance but abrade skin and clothing.

The problem is therefore not simply:

make a comfortable handle.

It is a systems-design problem.

Founding Hamre Forge

Hamre founded Hamre Forge in 2023 to produce functional grip solutions for revolvers.

The company was established as a family-owned operation in Maine, with products designed, tested, and manufactured there.

Hamre brought an unusual professional background to the project.

Before becoming a firearms manufacturer, he spent approximately two decades working as an infrastructure architect.

That experience influenced how he approached manufacturing.

Infrastructure architecture involves systems.

Requirements must be defined.

Components need to interact correctly.

Failures need to be anticipated.

Capacity matters.

Scalability matters.

Redundancy matters.

Processes that work once are not necessarily processes that work reliably at scale.

Those concepts translated surprisingly well into additive manufacturing.

From 3D Printing to Manufacturing

Hamre Forge began using conventional extrusion-based 3D printing.

That allowed rapid development.

A digital model could become a physical prototype relatively quickly.

The prototype could be installed.

It could be carried.

It could be fired.

Problems could be identified.

The CAD model could then be modified and another version produced.

This dramatically shortens the traditional development loop:

idea
↓
CAD
↓
prototype
↓
shoot
↓
evaluate
↓
modify
↓
print again.

That capability is particularly useful for ergonomically sensitive components such as handgun grips.

Changes measured in millimeters can substantially alter how a firearm feels and performs.

Moving Beyond Hobby-Level Printing

Hamre Forge did not remain a conventional desktop 3D-printing operation.

As demand increased, Hamre transitioned production toward Selective Laser Sintering — SLS — / Powder Bed Fusion.

Instead of building a component by depositing a continuous strand of melted filament, SLS uses a laser to fuse powdered polymer material into a solid component.

This creates different manufacturing possibilities.

Complex parts can be produced without the support structures required by many extrusion processes.

Multiple components can be nested within a build volume.

Mechanical characteristics can become more consistent.

The process can also produce geometries difficult or inefficient to create through traditional machining.

Hamre Forge ultimately settled heavily on PA-12 nylon powder for production.

Additive Manufacturing as a Production Tool

This distinction is important to understanding Hamre’s contribution.

3D printing is frequently associated with:

prototype

or:

hobby project.

Hamre Forge increasingly treats additive manufacturing as:

production manufacturing.

That means addressing:

• machine capacity;
• powder management;
• material consistency;
• dimensional consistency;
• finishing;
• hardware installation;
• quality control;
• inventory;
• production scheduling;
• OEM commitments;
• and customer demand.

By 2026, Hamre Forge had developed a purpose-built production space specifically designed around Powder Bed Fusion / Selective Laser Sintering manufacturing, operating multiple machines.

The progression was:

desktop manufacturing
↓
prototype validation
↓
commercial demand
↓
SLS investment
↓
production optimization
↓
OEM manufacturing
↓
dedicated additive-manufacturing facility.

Designing for the Human Hand

The grip is one of the most important interfaces on a handgun.

The shooter’s hand does not directly interact with the barrel.

It does not directly interact with the sights.

It interacts primarily with the grip and trigger.

Grip geometry influences:

• trigger reach;
• recoil management;
• muzzle control;
• consistency;
• draw;
• comfort;
• concealment;
• and perceived recoil.

This makes revolver-stock design deceptively complicated.

A small dimensional change can alter the relationship among:

hand → trigger → bore → recoil impulse.

Hamre’s products are therefore best understood as ergonomic interfaces rather than cosmetic accessories.

Compact Revolvers

Much of Hamre Forge’s development has centered on compact defensive revolvers.

Small revolvers remain relevant because they offer several characteristics valued by armed citizens:

• compact dimensions;
• simple manual operation;
• broad ammunition compatibility;
• unusual grip-shape flexibility;
• reliability in certain close-contact applications;
• and convenient concealment.

But small revolvers also present significant challenges.

They can have:

• substantial recoil;
• limited ammunition capacity;
• small factory grips;
• relatively heavy triggers;
• short sight radii;
• and reduced shootability compared with larger handguns.

Improving the grip is therefore one of the most direct ways to improve the shooter’s interface with the platform.

Craig Spegel

One of Hamre Forge’s most important associations is legendary grip maker Craig Spegel.

Spegel developed a reputation for exceptionally functional handgun stocks, particularly for revolvers and Browning Hi-Power pistols.

Traditional handmade stocks require substantial skill and labor.

That creates an obvious limitation:

a master craftsman has finite production capacity.

Modern digital manufacturing offers a different possibility.

A proven ergonomic concept can be preserved and reproduced through digital manufacturing while maintaining the functional characteristics that made the original design valuable.

Hamre Forge has produced modern versions of Spegel revolver-stock designs for multiple Smith & Wesson frame sizes.

Preserving Design Through Modern Manufacturing

The Spegel relationship illustrates a larger potential benefit of digital manufacturing.

Traditional firearms knowledge can disappear when individual craftsmen retire or die.

Templates are lost.

Processes disappear.

Knowledge that existed primarily in one person’s hands can become difficult to reproduce.

Digital design creates another possibility:

traditional design
↓
digital geometry
↓
repeatable manufacturing process
↓
continued availability.

This does not replace handmade craftsmanship.

It solves a different problem.

It allows functional design concepts to remain accessible at production scale.

Expanding Across Revolver Platforms

Hamre Forge expanded beyond a single J-frame product.

Its catalog grew to include products for:

• Smith & Wesson J-Frames;
• K-Frames;
• L-Frames;
• N-Frames;
• Ruger LCR/LCRx revolvers;
• Kimber revolvers;
• and additional platforms.

Each presents different geometry.

The Ruger LCR, for example, differs substantially from traditional Smith & Wesson grip frames.

Kimber’s revolver frame presents its own complex contours.

Hamre has publicly discussed stopping production when a design did not meet his expectations and revising it before returning the product to market.

That willingness to revise rather than simply continue selling an adequate design is an important part of the company’s development philosophy.

Prototyping and External Evaluation

Hamre’s development process has also involved outside testers.

RevolverGuy documented extensive test-and-evaluation work on Hamre Forge prototypes for the Kimber K6s/K6xs and Ruger LCR/LCRx.

That outside evaluation provides useful independent evidence concerning Hamre’s design process.

Products were not simply modeled, printed, and released.

They underwent iterative evaluation.

The development cycle becomes:

CAD design
↓
prototype
↓
external evaluator
↓
carry / live fire
↓
feedback
↓
design revision
↓
production.

That is conventional product-development methodology enabled by unusually rapid additive manufacturing.

Lipsey’s

A major milestone came when Lipsey’s approached Hamre Forge concerning grips for its revolver projects.

Hamre has described the opportunity to provide a grip for the Lipsey’s Exclusive Ultimate Carry J-Frame as the company’s first large commercial deal.

That is an important transition.

Selling directly to individual enthusiasts demonstrates that a product has consumer demand.

Being selected for a commercial firearm project demonstrates something different.

The component now needs to function within:

another company’s product specification

and:

another company’s production schedule.

That moves Hamre Forge from accessory maker toward OEM/component supplier.

Ultimate Carry J-Frame

The Lipsey’s Ultimate Carry project is particularly relevant because it reflects the same broader movement that Hamre Forge represents:

modernizing the defensive revolver without abandoning the revolver.

Rather than attempting to transform a revolver into a semiautomatic pistol, the goal is to improve the platform’s actual strengths.

That can involve:

• better sights;
• improved grips;
• useful chamberings;
• practical carry configurations;
• modern ammunition;
• improved manufacturing;
• and contemporary training.

Hamre Forge’s involvement placed the company directly within that modernization effort.

American Fighting Revolver

Hamre Forge also became associated with the American Fighting Revolver — AFR concept.

The AFR represents an effort within the contemporary training and firearms community to reconsider the revolver as a serious defensive tool using modern knowledge rather than nostalgia.

This does not require claiming that the revolver is superior to the modern semiautomatic pistol.

Instead, it asks:

If someone is going to carry a revolver, what does the best modern version of that system look like?

That question involves:

• firearm selection;
• grips;
• sights;
• ammunition;
• holsters;
• reloads;
• training;
• and realistic expectations.

AFR UnderCover

The Hamre Forge AFR UnderCover became a significant product within that ecosystem.

The grip was designed around practical concealed-carry requirements and received substantial demand from the revolver community.

By mid-2025, Hamre publicly described demand for the AFR UnderCover as exceeding available production capacity.

That is notable because the product exists in what would traditionally be considered a niche market.

It demonstrates that modern defensive-revolver development retains a meaningful enthusiast and practitioner base.

The Hamre Hook

Another example of Hamre’s willingness to reconsider conventional revolver interfaces is the Hamre Hook concept.

The design allows certain revolvers to be carried from the waistband without a conventional belt-mounted holster by incorporating a hook into the grip structure.

The concept is intentionally specialized.

It is not intended to replace every conventional holster.

Instead, it addresses a specific problem:

How can a compact revolver be conveniently retained at the waistband when conventional belt-and-holster carry is impractical?

This again reflects requirement-driven design.

Primary & Secondary — 3D Printing

Hamre’s expertise in additive manufacturing led to his participation in Primary & Secondary ModCast 413 — “3D Printing.”

The panel included:

• Ryan Hamre;
• Joshua Baier;
• Jordan Bowles;
• Nate Osborne;
• and host Matt Landfair.

The discussion addressed basic concepts of modern 3D printing and additive manufacturing.

Hamre’s presence was particularly relevant because he could speak from the perspective of someone using additive processes for actual commercial firearms-accessory production.

That provides a useful distinction between:

printing an object

and:

building a repeatable manufacturing process around additive technology.

Primary & Secondary — Modernization of Revolvers

Hamre later participated in Primary & Secondary ModCast 430 — “Modernization of Revolvers.”

The panel included:

• Ryan Hamre;
• Nate Osborne;
• Tom Russell;
• David Simerly;
• Scott Van Dorsten;
• and host Matt Landfair.

The discussion centered on bringing revolvers to a more modern level.

Hamre’s inclusion reflects his position within the contemporary revolver community.

His contribution is particularly relevant because he approaches modernization through physical product design.

The broader problem can be represented as:

traditional revolver
↓
identify enduring strengths
↓
identify obsolete limitations
↓
apply modern sights / grips / materials / ammunition / carry methods / training
↓
retain useful characteristics
↓
improve practical performance.

Hamre Forge operates directly within that process.

Primary & Secondary Connection

Hamre’s appearances on Primary & Secondary also place him within a broader network of contemporary firearms professionals discussing the practical evolution of equipment rather than treating equipment development in isolation.

His P&S association connects:

Ryan Hamre
↓
Hamre Forge
↓
additive manufacturing
↓
modern revolver development
↓
Primary & Secondary
↓
professional firearms and training community.

This is important because product development benefits from interaction with experienced users.

Firearms equipment exists to support human performance.

Manufacturers who remain connected to shooters, instructors, armorers, gunsmiths, and serious end users receive a continuing stream of feedback concerning what works and what does not.

Firearms Media

Hamre’s involvement with firearms media predates Hamre Forge.

Published firearms material credited to Ryan Hamre reaches back to at least 2010, including coverage of shotguns and firearms products from manufacturers such as Beretta, Benelli, Remington, and Briley.

This provides additional context for his later manufacturing work.

His involvement with firearms was not created by founding Hamre Forge.

The company emerged from a much longer interest in firearms and shooting.

Growth of Hamre Forge

Hamre Forge’s growth after its 2023 founding was rapid.

By the end of 2024, Hamre reported that the company shipped more orders during December alone than it had during its entire first year in business.

That growth created a new problem:

production capacity.

The challenge was no longer merely designing good grips.

It became producing enough good grips consistently.

That required additional manufacturing infrastructure.

Scaling SLS Production

By 2026, Hamre Forge had constructed a new production space specifically around Powder Bed Fusion / Selective Laser Sintering.

This represents a major milestone in the company’s evolution.

The progression from desktop printing to a purpose-built SLS production environment occurred in only a few years.

That makes Hamre Forge an interesting case study in how additive manufacturing is changing small firearms-component businesses.

Historically, entering firearms manufacturing could require substantial investment in:

• mills;
• lathes;
• tooling;
• fixtures;
• molds;
• injection-molding equipment;
• and specialized machinists.

Additive manufacturing changes some of those barriers.

It allows relatively small organizations to move from digital design to sophisticated physical production with considerably different capital requirements.

Additive Manufacturing and the Firearms Industry

Hamre’s work represents a larger technological transition.

3D printing is often discussed within firearms culture primarily in relation to home-manufactured receivers or controversial regulatory questions.

That is only one application.

Industrial additive manufacturing can also produce ordinary commercial components.

The important change is not simply:

people can print gun parts.

It is:

digital manufacturing allows small companies to design, test, revise, and commercially manufacture specialized products that may never justify traditional mass-production tooling.

Revolver grips are an excellent example.

The market may be too small for expensive injection-molding tooling for every possible frame and grip variation.

SLS manufacturing changes the economics.

Serving Niche Markets

This may ultimately be one of Hamre Forge’s most important contributions.

Additive manufacturing allows a manufacturer to economically serve smaller groups of users.

That can include:

• uncommon revolver frames;
• specialized carry configurations;
• limited-production designs;
• legacy firearms;
• enthusiast-driven products;
• and iterative experimental designs.

Instead of asking:

Can we sell enough units to justify a mold?

the question becomes:

Can we digitally design and efficiently manufacture enough units to satisfy this specific market?

That difference opens product-development opportunities that previously might not have existed.
