Episode Overview
P&S ModCast 126, “The Gauge,” is a long-form examination of the defensive and duty shotgun. Matt Landfair and a panel of experienced instructors, law-enforcement practitioners, competitors, and equipment developers discuss shotgun selection, setup, ammunition, patterning, recoil management, loading, maintenance, optics, weapon lights, safety operation, training standards, and the differences between pump-action and semiautomatic systems.
The central message is that the shotgun remains a highly capable fighting weapon, but it is not mechanically or cognitively simple. Effective use requires fitting the gun to the shooter, understanding ammunition and pattern performance, maintaining the weapon, and developing manipulations through competent instruction and realistic practice.
Host and Panel
Key Discussion Areas
Selecting and Configuring a Defensive Shotgun
Panel members describe their preferred defensive or duty configurations, including the Remington 870 Police, Beretta 1301 Tactical, and Benelli M1 Super 90. The discussion emphasizes intended use, reliable components, proper stock dimensions, accessible controls, ammunition compatibility, and professional setup rather than copying a universal parts list.
Pump Action Versus Semiautomatic
The panel compares the manual demands of pump-action shotguns with the ammunition sensitivity and maintenance requirements of semiautomatic systems. Familiarity with a pump does not automatically make it easier to use under pressure; shooter strength, technique, pacing, recoil control, and reliable cycling all matter.
12 Gauge, 20 Gauge, and Recoil
The episode challenges the assumption that a lighter 20-gauge shotgun necessarily produces a better recoil experience. Gauge, firearm weight, stock fit, ammunition, action type, and technique interact. Selecting a smaller or lighter gun without evaluating the complete system may make the shotgun less comfortable or harder to control.
Buckshot, Patterning, and Ammunition
Pattern density, point of impact, distance, wad behavior, and load selection receive extensive attention. The panel explains why defensive ammunition must be patterned through the individual shotgun and why no load—including Federal FliteControl—removes the need to understand the gun’s performance across realistic distances.
Loading, Maintenance, and Reliability
A shotgun demands sustained attention to ammunition management and mechanical condition. The conversation covers loading-port concerns, ammunition sensitivity, tube order, regular cleaning, wad fouling, and function testing. Alternating or “staggering” different loads in the magazine tube is rejected because it complicates accountability and creates avoidable uncertainty.
Less-Lethal Ammunition and Dedicated Systems
The panel distinguishes professional less-lethal programs from civilian defensive use. Specialty impact or chemical-agent rounds require policy, training, identification, dedicated weapons, and strict ammunition controls. The episode cautions civilians against treating rubber buckshot or similar loads as a simple intermediate-force solution.
Optics, Lights, Safeties, and Storage
Shotgun-mounted optics and lights must survive recoil and remain accessible during manipulations. The panel also compares safety locations and operating procedures among common shotguns, including how agency policy, vehicle storage, chamber condition, and the specific weapon’s controls affect deployment.
Training Standards and Institutional Knowledge
Patterning, loading, recoil management, aiming, target accountability, malfunction prevention, and ammunition selection are presented as essential skills. The panel criticizes treating the shotgun as a weapon that requires little training merely because it has long been common in homes and patrol vehicles. Competent instruction should precede major equipment purchases whenever possible.

Practical Takeaways
- Pattern the specific shotgun with the exact defensive load.
- Fit the stock and controls to the shooter and intended role.
- Do not confuse familiarity with simplicity or competence.
- Test semiautomatic shotguns with the ammunition they will actually use.
- Avoid mixing different loads in the magazine tube without a narrowly defined professional protocol.
- Use sights and aim; the shotgun does not remove target-accountability requirements.
- Build skill in loading, recoil management, manipulations, maintenance, and ammunition selection.
- Seek instruction before spending heavily on modifications.
