Ok, apart from the fact the top model is a 640, all steel, and shoots .357, and the bottom is a Airweight 642 that shoots only .38+p, what is the difference? Both are J-Frame Smith and Wesson revolvers. Both are DA only models. What else is different.Yeah, the grip looks different. Both are made of that rubberized Hogue material, but the 642 looks smaller. The 642 doesn't have the full underlug on the barrel, either, but concentrate on the grip.
Could the 642 grip go on the 640? Because grip size is where people will notice you are carrying CCW. Shave a bit from the grip and you make it more concealable. And those two grip styles, above, are the two standard rubberized grip types.It's hard to tell without holding each model in your hand. But that 640 (top) is bigger, all around, isn't it? Sure looks it. Not just the grips. Even with the same frame designator, J. Or am I seeing things?
This is important. Size and concealability is what you are looking for with a snubbie. I'd live with the extra weight of the all steel 640, and probably just shoot .38 +p though it anyway (same witht the 642) but not if it is bigger.
I'd swap the grip out in either case to something like this:
There has been a run on the blogospher talking about the rubberized grips are grappy around clothes and can hang you up a bit. The fact those rosewood grips go on either model makes me think that the two varieties of black rubber grips go on either model, but I don't know that.
