Everyday carry is about ruthless efficiency: the tool you choose must disappear when life is quiet and deliver when life gets loud. Minimal size, maximum dependability—no fluff, no gimmicks. That’s the standard I hold to when a pistol rides in the pocket as a true last-resort companion.
HEIZER DEFENSE DOUBLE TAP
Why this Derringer earns pocket space
In the Derringer category, weight and width are the currency of concealment. The DoubleTap is a razor-thin 5/8 inch wide and just 13 ounces. That makes it one of the slimmest, lightest tactical pocket pistols you can actually forget you’re carrying—until you need it. When you’re stacking layers—belt gun, blade, light, med kit—this pistol slides into a pocket or ankle rig without upsetting the balance. It’s purpose-built for the moment you never want but plan for anyway: a last-ditch, life-and-death scenario where a big-bore punch in a micro package matters.
Heizer Defense didn’t compromise on the build to hit that footprint. Every pistol is 100% made in the USA and fully CNC-machined—no stampings, no MIM parts, no plastic, no castings. That matters. When tolerances are cut instead of molded, you get consistent lockup and longevity, the kind that survives pocket carry, sweat, grit, and time. This is a backup gun you can actually trust.
Materials that take abuse
17-4 PH guts, not bargain-bin steel
Internal parts and barrels are machined from 17-4 PH stainless steel, a major step up from common 416. The payoff is strength, hardness, and corrosion resistance—key traits in a pistol that might ride close to the body day in, day out. In plain terms: it shrugs off sweat and keeps its edge when you press it into service.
Frames: aircraft-grade or titanium, both with a duty finish
The frame is cut from 7075 aluminum or 6Al4V titanium, both finished to MIL-STD spec. If you prefer the lightest carry possible, 7075 has your back. If you want near-indestructible with a few more bragging rights, titanium delivers. Either way, the frame resists wear and stays tight under recoil.
Lifetime warranty
Confidence is built into the warranty. Heizer Defense backs the pistol for life. If a backup tool has one job—work when everything else doesn’t—this kind of coverage is part of the equation.
Caliber flexibility without buying a second gun
Interchangeable barrels unlock multiple caliber options on the same platform, including big-bore choices ideal for close-range emergency defense. Swap barrels to match your mission: carry the punch you want, then train with a more manageable option if that’s your preference. The platform keeps things brutally simple—two rounds on tap when distance collapses and timing is measured in heartbeats.
Carry reloads where they matter
The DoubleTap stores two spare rounds on a speed strip in the butt of the pistol. It’s smart, efficient, and faster than fishing loose cartridges from a pocket. In a design this compact, that onboard reload is a thoughtful upgrade that can buy you precious seconds.
Retention ready
A rear grip lanyard loop lets you attach a retention device. Whether you’re on a trail, on a boat, or working in austere conditions, retention can save your day. Pocket guns are easy to carry—but also easy to lose track of during intense movement. This solves that problem without getting in the way.

How it carries and fights
Pocket and ankle carry that stays invisible
The svelte 5/8-inch profile means it rides flat and prints less, even in light clothing. Use a quality pocket holster to break up the outline and keep orientation consistent. An ankle rig pairs well with duty carry or formal wear—access with your support hand when your strong-side is blocked or occupied.
Recoil and control
Physics won’t lie: a 13-ounce big-bore derringer will speak with authority. That’s fine, because its mission isn’t a 25-yard bullseye—it’s contact to conversational distance, decisive and immediate. Train the press with a locked wrist and strong grip. Drive the muzzle flat, break the shot, recover, and deliver the second round on demand. Dry practice your drawstroke from your chosen holster until it’s automatic and safe.
Sights and aiming strategy
At the ranges this pistol is built for, build index and alignment more than traditional sight refinement. Present consistently, keep the bore line married to your visual target, and avoid pushing shots low with a hyper-aggressive press. With interchangeable barrels, consider a training barrel for volume reps and a defensive barrel for carry—your grip and presentation stay the same.
Maintenance and durability
Stainless internals and barrels resist corrosion, and the MIL-STD frame finish stands up to real-world carry. Keep it simple: wipe down after carry, inspect the hinge and locking surfaces, and maintain the barrels you use most. The CNC-machined construction means parts interface cleanly; treat it with basic care and it will outlast a drawer full of disposable pocket pistols.

Final thoughts from the belt line
When I evaluate a backup gun, I ask one question: will it be there, and will it work? The HEIZER DEFENSE DOUBLE TAP answers both with a resounding yes. It’s thin enough to vanish, tough enough to ride daily, and powerful enough to matter at the only ranges a pocket derringer is meant to solve. If your EDC demands a compact ace up the sleeve, this one deserves your pocket space—and the training time to run it right.
