is there a little hole on the left side just above the cylinder release latch? if so it has a lock. Smith and wesson's response to government oversight during the clinton administration.
I still have the box and paperwork for the 629, a cardboard box that's really too thin for the pistol but it has the correct label. This thing has the sweetest trigger I've ever felt, somebody did some great work on it.
Not really interested in selling it right now, but thanks a million for the information, both of you. Best of luck finding the one you want.
