I carried a Kahr PM9 with extended mag in a Milt Sparks Versa Max II IWB holster in a 7+1 configuration loaded with Winchester Ranger SXT 127 gr +P+ loads for years here in sticky, sunny south FL. After a few years, I felt kinda naked without it.
To go a little lighter, and just for something different, a couple years ago I started carrying a little 642 J frame with Crimson Trace laser grips in a sticky neoprene Blackhawk holster in my strong side back pocket and a couple speed loaders in my other side cargo shorts side pocket.
I keep a Beretta PM9 under the seat with an 18 or 20 rd magazine, also loaded with Winchester Ranger 127 gr +P+ rounds. The truck always carries on board several other l8 and 20 rd magazines in the console. This is my go to gun when I'm inspecting any "empty" houses.
