The 637 is a very nice gun and delightfully suited to pocket carry. Having said that, it is also a little less "quality" finished than the stainless or scandium finished Smith revolvers. You will notice some minor quibbles, but certainly nothing that anyone but the biggest critic would take much issue with. The finish does wear and weather rather poorly, but Smith may refinish for you under warranty, not sure on that, but their CS is legendary.
IMO, if I had doubts about the 637, I would either move to the 360 .38+p only model or the M&P 360. Better fit and finish, lighter, and possibly the finest pocket carry guns ever made.
