Man, the information stockpile on this site is awesome. So it looks like I'm on the hunt for a 629-4, if I can find one with the case hardened hammer.

One last thing I've been noticing... some stainless S&W revolvers appear to have blued front sights that are staked/pinned in place, while others appear to have stainless sights that are actually one piece (part of the barrel)? Did this vary within a given model number, or did this change when they went from -3 to the -4? I could swear most of the 629-4 guns I've seen have the blued front sight, but the one 629-4 6" half lug I've found seems to have an integral stainless front sight. I'd prefer the blued removable front sight if possible. Was there any consistency to this option by model number/configuration, Or is it just random?
