Not sure who posted earlier about the HK P7 having a roller lock, this is not accurate. The P7 has a gas delayed blowback action. The P9 is the one with the roller lock.

I had a P7M8, it was very nice to shoot and I think it has the best sights of any pistol I have yet shot. It turned out to not be my favorite though because it would heat up fairly quickly when shooting at the range or IDPA club shoots with too few people. The 'heat shield' on the M8 does not seem to really be too effective. If/when I am able to buy a guy like this again I would probably go with the classic version instead of the M8, they have such nice lines.

Has anyone tried the Kel-tec PF9? I have heard they are very reliable, once broken in, have a nice trigger (relatively speaking of course), are very light and slim. It seems an ideal pistol for CCW.
