Looking at the full S&W lineup I see that there are two basic barrel lengths, only about 1/4 inch difference, the 2.1 in and the 1.9 inch. I can't imagine that this small difference in barrel length is significant in terms of the power of the round, and wondered why there are these two different lengths. Is it just for cosmetic reasons, i.e., that the slight difference gives the gun a different look or am I missing something more important? And while I am on barrel length, maybe someone can tell me how much difference in stopping power there might be between my Model 640 with the 2.1 inch barrel and my Model 19 with a 4 inch barrel, firing the same 38+p ammunition? I would never part with my 19, which is my favorite go to gun, but the 640 is much more suitable for carry in a pocket holster.
