Here's the ultimate gun for concealed carry, if your pocket is better described as a salient. For example, the Kursk pocket. I am particularly impressed by the terminal performance, though without recovering the projectile, we cannot judge expansion properly.
A semi-automatic shotgun with a familiar look and feel.
An outside-the-waistband holster made for smaller pistols.
AR-pattern 9mm upper and lower receivers which use Glock-compatible magazines.
