Yep, I dry fired it a few times. As you know, I'm a 1911/target guy, so yeah, DA is not my favorite, but I found the Kahr much better than a Sig. The only thing I didn't like was the grip length, but it's short for a reason.
I know the MK9 is half a pound heavier than the PM9, but I had the opportunity to drop it in my pocket and it wasn't bad at all. Of course, it was unloaded, and seven rounds might just put it over the top.
I'm taking my CCW course next week, so I'll have my permit in a few months. Plenty of time to find a PM9 somewhere. I plan on pocket carry most of the time, especially because I'm going to sell my Kimber once I get my Colt back from Ted Yost. The Kimber's great but it's no Yost custom.
