I thought about the K40. Ended up getting a T40. It shoots fine, but kicks more than my S&W M2.0 and is about the same weight empty... pretty similar in size too. However, the CW40 I have is not accurate and has hiccups when returning to battery. This is after I sent it in to Kahr to fix... at least their CS department stopped it from choking every round. It seems like the accuracy went up a little after the fix, but it is still pretty bad. No issues with the T40 though. Still experimenting with it... just not much time/$$$ righth now.
