.45 with less "punch-through" than a 9mm???
What kind of crappy .45 are you shooting?

[dannyc]

The 9mm will punch through a wall or the side of a house cleaner thaqn the 45 acp so the chance of shooting your neighbor is higher with the 9mm.

A nine mm is just to small IMHO for personal protection.

The other thing with a Semi auto is that you must put a lot of time in on the jam clearing drills etc. If you are going to depend on one of them for protection. I elected to not spend countless hours on those drills and just use a revolver. Simple, no jams. I don't have the amount of follow up shots but I am not in law enforcement and will just hope that 6 will do the job.

Check the muzzle velocity and mushrooming of the two rounds and you'll see. The .45 was designed around the round, to stop a human in their tracks with one shot.

CorBon 185GR JHP +P, thats what! Bigger hole = more air in, more blood out! Probably wont penetrate thru and thru, but it will sure screw up everything close-by.

Exit wound = probable liability. Who needs that!

The correct expression is penetration.
9mm’s are a faster round and usually have greater penetration than the larger and usually slower .45acp round.
