Man this is a tough call....I have both a PM9 (accually 2 PM9's ) and a P3AT.
The Kahr PM9 is the ultimit pocketgun loadded with 7 rounds of corbon 100g powRball UNTILL you put a P3AT in your pocket.
I don't care much for the little 32acp's in any flavor for the sole reason the round give's me ZERO comfort. I will admit I would not want to be shot with one but I don't like it as a defensive round.
That said..I like the 380acp in the P3AT package. I use winchester 90g sxt's, acurate, nice punch and make a bigger hole than any 22,25 or 32 in a similar pized package. Hopefully by the end of 2003 corbon will have a 380 powRball.
To answer your question my carry PM9 has Novak nitesites and I was carrying a 8rd T-9 magazine for spare.
This was a perfect pocket setup for me...as good as it gets I thought... But since I got the P3AT in the first part of june the PM9 has been left in my safe for bedtime duty and the P3AT has not left my pocket.
The Damm thing is just so small,so thin, so light, it works and it has 380acp punch......
Thats what I tell myself anyway...The PM9 is a superior defensive piece IMOP because of round it fires, and the sighting system but for the role of a pocket piece they both are comforting BUT the P3AT is more comfortable hands down...
