I recently picked up a S&W 637 which I like very much indeed and will probably have the hammer bobbed off since I couldn't locate a 642
637Both are 38 plus P rated
642Carry of either one of these is a charm, but what I couldn't understand is that Taurus airweight was even priced higher than my 637 that I picked up for $399.99
Now in your selection of what you carry, I would wear something that you most commonly wear during the hottest days of summer, see how well it conceals right there in front of the sales people. Tell them you got to see how well it conceals etc. I used to be a Semi Auto guy all the way carrying Glocks in 27, 23, 19, 17 and 22 and found bulk where I wanted slimness and not the battle of the buldge. Then weight was a big factor, so when I went back to wheel guns I got a Taurus 44C in .44 Mag and with its 2" barrel it hides real well. But the weight was less desiring as was the weight I noticed with the Taurus 605 and 85 for pocket carry... the Airweight for CC just fit the bill. But I decided I wasn't going to fool around with Taurus any longer, I set out for AMERICAN MADE period and the S&W's won out even over a Ruger SP101 which is a nice gun in its own right, problably one of the strongest made out there.
But I didn't need strength for high power loads or the trail as the Taurus 44C will fill that duty. When I first looked at the S&W 637 the guy behind the counter says, "Its ONLY a .38 man" I looked at him and asked, "Whould you stand in front of it?"
He looked surprized at my remark... but I told him that just because its a .38 Spl doesn't mean it will not fill the bill as a good solid CC gun, and work when needed... as shot placement is the key to putting down and ending the fight if need be.
So see what fits your hand etc, as it has to fit you and your needs not anyone elses.
Over 25 yrs ago a Smith & Wesson mod 19 was my first purchase, and my duty gun was a model 10 I believe, and was also just a .38 Spl in a 4" barrel with no rear sight which was standard issue for Air Force AP's at the time (1974 - 1976)
I just got smart and came back full circle.
