I bought a pair of their Heritage round-to-square conversion grips for a 629 a few years back. Although the grips were, and are, unquestionably beautiful, the fit was not at all good - there was a clear gap between the frame and wood on the upper part of the right-hand grip. I called them and was told that it was due to variations in the size of the frame between guns. Funny, I've swapped plenty of factory S&W grips over the years and they all fit perfectly. They offered to custom fit the grips if I sent the gun to them (and paid the shipping both ways, 'natch), but I opted not to go through the hassle and expense. Have since bought Altamont grips for S&W revolvers and semi-autos and they all fit just fine.
