Hey, Jim.
No flame, you are obviously quite thoughtful and analytical; but, food for thought.
First, anyone who has let the threat get close enough to allow the muzzle contact you are worried about may find that he/she has just lost his/her life to the bad guy with a knife.
And there are many reasons, assuming such close contact, NOT to press the muzzle against the opponent. For one, it lets your opponent know where your weapon is without having to look for it and you may just find that it has suddenly been taken away from you.
If someone can get their hands on your gun, you may find that they have the leverage to do just that; and, they may also be able to prevent you from fireing while they are doing it. Did you know that grabbing the cylinder of a revolver can prevent its rotation and make DA trigger pull impossible? And a thumb or finger between the hammer and frame can prevent you from firing even a cocked revolver?
There are many pros and cons on both sides of the revolver v.s. semi-auto argument; but, IMHO out of battery caused by muzzle contact is not one of them.
I don't want to start that argument of revolver v.s. semi-auto here (besides I use both).
It just seems to me that you're giving too much weight to a non-issue. :banghead:
For pocket carry, first consideration is being able to get it into and out of your pocket. Darn! That rules out my 629 classic.
Next consideration is whether the chosen cartridge is capable of doing enough damage to be of any use. As I said in an earlier post - Bigger Hole = Better - That's why I choose 32 acp over .22 LR, 22 WMR, and .25 acp.
Third consideration is delivery system and these are the reasons I choose P32. Yes, I'm considering moving to the P3AT.
Admittedly, there must be some compromise between the second and third considerations.
Now, if only Kel-Tec would come out with a version of the P32 in Cal .45 ACP ....
