PM9
I own a PM9 and have shot the CW9. Recently, I shot them both during the same range session. Both are fine pistols. Obviously, there is a size difference between the two, but really, as far as a carry gun is concerned, both are nicely concealable. The CW9, in my opinion, is easier to shoot during an extended range session. Prior poster made an interesting comment about holsters though. If the difference was $300, I'd say go for the CW9. $185 difference makes the call a lot harder. Personally, I'm happy with my PM9. You'll be happy with either choice. Good luck.
PS - anyone - can these candle +P? I looked in the manual but couldn't find anything.
