I am not particularly recoil sensitive and have fired handguns in most calibers. I have carried and shot .38 snubbies for years using +p ammo with no problems. I had to have one of the Smith 340 M&P's when they came out. What a great idea! A lightweight .357! Not for me. Even the mildest .357 load was like holding up my hand and letting someone rap it with a pool cue. I fired exactly 20 rounds through it and went back to carrying +p .38's. I finally sold it to someone who just had to have it. He still carries it but with .38's. I have regressed to a Colt Cobra loaded with Hornady XTP 158 grain non +p. It's more accurate for me, holds six, and follow up shots are quicker.
