Mr. Ayoob.

I want to thank you for answering my past questions and this one.
I live and carry in Fl. and since the shooting in Sanford I have been thinking about over penetration in a self defense situation in a outside or public area since something like a robbery will only be about 2 or 3 feet away which has me rethinking which gun to carry and with what ammo to lessen a chance of a round exiting out of a bad guy and into a bystander. Home self defense I have covered it's outside that has me thinking. In your opinion if you had to decide between a .38 snub, .44 spl. 3", LC9, G19, and my favorite a G30 which would you choose and which ammo to lessen the chance of over penetration. I would think the .45 with HP since it's a slower round or the .38 snub with HP. I'm thinking the 9mm is to fast so may exit a BG. Any thoughts I would really appreciate. All this stuff happening has a lot of us rethinking on what to carry and the worst part is someone may hesitate a second in defending them self because of all this garbage going on. Any advise would really be appreciated.

First, Mikie, there's no guarantee it's only going to be short range.

Second, while prefragmented bullets of light weight at high velocity are THEORETICALLY ideal for that application, most auto pistols are designed with slide mass/spring compression ratio built around a certain range of standard ammunition. I've seen a lot of malfunctions with hypervelocity lightweight bullets in semiautomatics.

In conventional ammunition, bearing in mind that like you I'm more concerned about corollary damage from overpenetration than some others on the forums, I'm personally comfortable with Speer 135 grain +P Gold Dot in the .38 Special, Winchester Silvertip in the .44 Special, 124 to 127 grain high tech JHP at about 1250 fps in the 9mm, and modern high-tech 230 grain JHP in the .45.

If you want to lower penetration a bit, the Winchester 185 grain Silvertip is available in .45 ACP, and the various 115 grain JHP 1300-1350 foot-second 9mm rounds will generally do only about 10" penetration, but with a wide wound channel.

best,
Mas
