Cooper said a 40 gr .22 Spitzer has enough power

to stop men reliably, if it is going 2200+ fps. At such a Mach II speed, the hydrostatic shock means more than bullet diameter or momentum, according to Jeff. He said that such a .22 spitzer would be adequate, even after pierciing a Kevlar vest.

A 9mm bullet has 2.5x the frontal area of a .22, and the 60 gr .38 Casull load achieves 2300 fps in a 3"long barrel, making a pocket gun out of the 1911 (if the Laughridge lockwork is used, letting you carry the gun hammer down. No long tang of the grip safety is needed.

Move the mag catch to the bottom front of the frame, ala the Citation military High standard .22, and you can do a Firestar like "sinus" of the rear bottom of the trigger guard. That lets you get your hand 3/8" higher on the gun butt. Add a PPK type of pinkie extention to the the bottom front of the mag, and you have a real pocket gun. One with twice the stopping power of a normal 1911, full of 230 gr jhp's.

If the 60 gr bullet is made of pure Tin, it is AP on kevlar vests. Its huge hollowbase makes the bullet "nose heavy", and that keeps it driving in its original direction, even after the hp collapes in wood, steel, or Kevlar. or after the front 2 segments break off in flesh, and tumble, tearing their own separate wound channels. These "Split Nose" bullets are $55 for 20 of them, shipped, from Paul Stout, 2224 Herman Rd, Ashton, ILL. 61005. Specify .45 or 9mm, 55 or 60 grs in 9mm, 70 or 80 grs in .45. The pure tin swc can be had for $30 for 20 rds, shipped, or the hollowbased swc can be had for 40 for 20 bullets, shipped. The .45 weighs 105 grs without the hollowbase, 90 grs with the HB. It is not at all difficult to get the latter going 2000 fps in a 4" barreled .45 ACP, if you have a fully supported barrel.

I really have not cared much what Cooper has had to say for the last few years now. I'll stay with what I know. But thanks for the info.
