I carry a 442/642 no lock more than anything else. Sometimes a 36 (with bobbed hammer), 49, 640 Pro. I don't generaly like new S&Ws for a variety of reasons, but I will give credit where credit is due. My older J-frames needed shims and had other issues. Newer 442/642s needed nothing.
Crimson Trace (LG105 & 405 depending on your preference) lasers are a very worthwhile addition especially with aging eyes. I have them on my EDCs.
Preferred holsters: Dark Star Gear for AIWB. Doesn't even require a belt. Pocket carry (usual) Kramer, Mika, A-holster, Safariland depending on your preferences. Phlster Enigma for non-permissive environments (but a SIG P365 MS is better in that role IMO).
Preferred ammo is Federal Gold Medal 38 Special Ammo 148 Grain Match Wadcutter & Speer Gold Dot Short-Barrel 135-grain JHP +P.
I've recently had a few experiences making me aware that the old days of one or two bad guys are probably gone and J-frame becoming more of a second gun (like everyone I have lazy days and take shortcuts).
Also, following shoulder surgery if you have a pocket holster for off hand carry or a phlster city special (or other ambitious) you are still up and running.
