Notice that it uses RIFLE primers?
Without super lw bullets, and in short barrels it's worthless, but with big, conical hollowbase cavities, and very short, solid copper bullets, the pocket 9mm's can be made to (safely) offer 45 grs at 2200 fps, 500 ft lbs of power, with no more recoil than a Makarov. Recoil is momentum, mass times velocity. 45 grs at 2200 fps is the same thing, recoii wise, as 90 grs at 1100, or 110 grs at 900 fps. If the hollowpoint is split down the center, from nose almost to base, it can be made to fragment at impact, delivering 2 wound tracks per hit, and those frags are hard, sharp-cornered, and unstable. They tend to yaw, go sideways a bit, creating a big wound channel. The Mach II impact speeds (at pocket pistol distances, sub 10m) mean that the temporary gas-cavity WILL do permanent damage to fragile organ tissues. So such tissue as ends up "between" the 2 permanent cavities gets destroyed. The effect is a 3/4"x 1.5" (average) wound track thru the target. The problem is, such ammo is AP. It's not illegal to possess, except in CA or ILL (which require a "lead core" for handgun bullets) but the maker would be making cops VERY upset with him. So you have to settle for low-probability stopping-effect in your pocket 9mm, cause the cops dont want you to have stuff that really works.
