The Kahr Arms P380 is the most Glock-like .380 auto - note that most .380 auto pistols don't even have a locking slide nor slide stop/release lever, but the P380 does:



may have been a Sig .380 micro
That would be a Sig P238. It is the same size as the Kahr Arms 9mm PM9. the P238 is exactly like a mini 1911 in that it has a safety, has an external hammer, etc.

I'd rather have a 9mm is it's going to be the same dimensions, in fact, the PM9 weighs less too!



I happen to own both a PM9 and a PM40 and the PM40 fires the .40 S&W round and is still the same size as the Sig P238:

So do you want to simply piss someone off (shoot them with a .380 auto) or kill them (shoot them with a +P 9mm lugr or .40 S&W) when he/she attacks you?
