S&W 629-5 (Mountain Gun) problem

I'm hoping someone who knows these guns can point me in the right direction to fix a problem that has developed with my .44 mag MG that I purchased used a couple of months ago. The issue is that the cylinder will not release from the frame when the release is moved forward. It appears that the locing bolt is not traveling far enough to clear the recess or hollow end of the extractor rod. In order to free the cylinder, I have to 'help' the locking bolt forward with a small blade screw driver. I believe the problem is associated with the locking bolt as it looks a little worn at he end that is sort of sharpened but hope someone can shed some light on what is needed to fix this problem.

Thanks much,
Jerry
 
Have you checked to make sure that the ejector rod is tight as a backed-out ejector rod is a fairly common issue. The problem you're describing is almost exactly what one would expect from an ejector rod that's backing out. The first thing that I would do is to make sure the rod is tight (remember, it's a left-hand thread) and if it's not, I'd remove it and put a drop or two of blue Loc-Tite on the threads before reinstalling it.
 
Thank you gentlemen. I'm going to look into it and see if it fixes it. It does seem that the previous owner used pliers or similar to tighten or remove extractor rod as the knurled end is a bit marred.
 
$ 20 or so with shipping ...isn't that bad -compared to looking at a rod that someone used pliers on .... / geez, some of the stuff you see guys do to guns is pretty awful..and foolish / with a little bit of research, it could have been easily prevented...
 
Looks like it was a loose ejector rod. Tightened it up snug to the left and the cylinder opens freely. However there now seems to be some friction along the rod travel. Will disassemble and do a thorough cleaning and lube. Thanks again and i'll probably go ahead and get the new rod from Brownells.

When you disassemble it, be sure not to over lubricate the rod or any of the other internal components. One of the easiest ways to give yourself problems with a DA revolver is to over lubricate it. Really, all that's needed for internal components is a drop or two of good gun oil (I like RemOil myself) on the contact/friction points. Over lubrication attracts dirt, lint, and other problem-inducing debris unneccessairly. Also, if the wrong type of oil is used ('cough' WD40 'cough') it can dry and leave residue that gums up the works.

Another possibility is that the previous owner bent the ejector rod slightly in his plier-induced fit of madness. Given that possibility, you're probably making a wise choice to get a new rod from Brownells and be done with it.
