In a visit to my LGS I spotted a no-lock 642 Pro, (Pro model can use moon clips for a ridiculously fast reload). Having a Model 36 at home, I was familiar with a short barreled S&W. I held it and marveled at it's lightness. Not much weight to counteract the physics of shooting a .38 Special +P but that didn't deter me from bringing it home! Of course I took it apart and polished this and that. I ordered different springs from Wolff. Once I installed those and had tested it with all forms of ammo I'd be carrying, I'd select the 642 for carry more days than not. Range days the 642 came out more often than not. I've become pretty good at hitting my intended target with 158 gr. .38 Special. After verifying I can hold the gun through 5 rounds of +P, I carry with +P but practice with .38 Special. On colder days, (hide it under a coat in a holster), I sometimes switch grips and use the full hand square butt grips which really aid in control. I don't think you can go wrong with the 442/642. If the trigger is too much for you, consider different springs. A change of grips can make a world of difference too. I love my 642 so much that I sold my LCR and I'm feeling guilty about how little I carry my SP101!
