S&W M&P Shield.
Then I have just gotten a CZ-82 that I haven't shot it yet and people say it kicks hard, but at 6oz. heavier than the P-64 with much more purchase on the grip it can't be as bad.
The P-64 is a snappy little bastard but the CZ-82's are tame and quite comfortable in my experience. Maybe the folks who thought it "kicked hard" were expecting the 9x18 to be a much weaker round or the grip just didn't work with their hands?
