Living in sunny Florida, my primary carry is .32 cal in my P-32
I own a S&W 4516, and carry it occasionally, but at 36 oz. empty, it's like lugging around a bowling ball on your hip.
I'm considering an inexpensive 9mm to replace the Kel-Tec. Taurus PT-111 or something similar. Weight of the 111 is 18.4 oz empty.
Glocks are nice, but out of my price range.
