Self defense ammo in .32 S&W (New Police) long
I have had a carry permit since 1974. I have packed a 9mm Star "Starlite", .45 Light weight Commander and now carry my "American Express Card" Colt Police Positive .32 New Police. The gun has been dehorned, grip shortened and 4 inch barrel cut to 2 inches. It weighs 14 oz. and carries 6 rounds with 2 different hand loads 100 grain hollow base wad cutter (loaded upside down) and 115 grain linotype cast round nose (for .30 carbine). I load this with 2.7 grains of Bullseye (both bullets). Muzzel velocity runs about 820 to 850 fps. resulting in about 150 ft/lbs energy.
The key here is I never leave home without it. Wether I'm in shorts and T-shirt or dress clothes and sport jacket. You want a gun you can carry 24/7. The pocket cannon may be reasuring, but packing 2 to 3 lbs of iron and getting jabed in the ribs while trying to conceal it gets old real fast, resulting in going unarmed 50% of the time.
Muzzel energy ranks right in there with the .380 auto. The revolver results in mutiple ammo assuring both penetration and expansion. This is a "double tap" revover and at 7 yards I'm good for head shots.
My biggest threats come from pit bulls, but their owners get the message when I don't back down and draw down on them. Here in FL, home invasions become more and more common by the day. They try it at my house, they are in for a big suprise.
