I usually grab a 2” 38sp of some stripe when I head to the fishing hole. I shoot snakes and pigs when necessary out at the bass pond and the lake and creek I usually catfish has been known to have the occasional meth lab around hidden in the weeds. I feel a little bit better with a 38 and an extra speed strip when poking around down there at night.
I’m an S&W guy so it’s a 36, 10-5, or my 15-3, all 2” for me. But I’ve given the 3” LCR some thought too. Would probably buy one if it would fit any of the holsters I already own.
