S&W hammer block problem

[Rio Laxas]

I have a 629-1 that I bought supposedly new in box a few years back. Come to find out that it probably was not. I had it in with a gunsmith to repair a hammer push off problem. I had removed the sideplate before giving it to them to look at the trigger and hammer surfaces, and I forgot to put the hammer block back in. Well, I got the revolver back and now the hammer block is giving me trouble. If it is not installed, the revolver works fine. If I put it in, then it somehow interferes with the trigger rebound and it hangs up as the trigger is released to come forward. Any ideas why this might be?

Okay....I need a little more information here.

You took out the hammer block....did the gunsmith install a new one...OR are you trying to put the old one back in?

Did the gunsmith intall a new hammer in the process of fixing the push off issue? Did he fit any other new parts in the repair process?

Let me know

Cheers
Mac.

I am trying to re-install the old one. The gunsmith did not install another one. To my knowledge, the gunsmith only recut the sear and did not replace any parts.

I doubt the gunsmith "recut the sear" or recut the hammer notch. It can be done, but few gunsmiths have the equipment to do it, so I suspect he simply installed a new part, either a hammer or trigger. In any case, something he installed is rubbing on the hammer block or the hammer block itself is bent and rubbing.

(I assume you are installing the hammer block correctly with the hole over the small pin in the rebound slide.)

Two things:

If the gunsmith recut the hammer notch, he probably ruined the case hardening.

And if he returned the gun to you without a working hammer block and didn't clearly warn you of the drop safety issue?
He isn't a gunsmith.

I think at this point, I would send it back to S&W for proper repair.
It will be money well spent in the grand scheme of things.

The trigger is the same one that I sent it to the gunsmith with (smooth target, flash chromed) and neither it nor the hammer are case hardened. They are flash chromed. I don't know if that makes a difference. The invoice says that the sear was re-cut. The gunsmith was Briley Mfg. For what it's worth, the hammer push off problem seems to be fixed.

Good grief!

I simply can't believe Briley would return a modern S&W to a customer with the drop safety block missing!

Maybe you should talk to them about it not working now.

I had actually lost the part in the couch and I asked them to order me a new one and install it, but they said they could not obtain the part. I could have ordered one myself from Numrich, but I found the part. It appears to be rubbing up aganst the trigger rebound spring assembly. I don't understand why it no longer fits when no parts were replaced.

Maybe it got bent somehow?

But I don't see any way possible it could rub on the rebound slide spring even if it were bent.
It fits clear inside the recess in the sideplate, and on top of the rebound slide. The spring is compressed way down inside the rebound slide hole.

You sure you are putting it in the right place where it goes?

Yep, just like that. I have also determined that the hammer block itself is not the problem because I switched them between my 657 and 629 and got the same result....worked in the 657 (which Briley also worked on) and not in the 629. I was searching old threads on smith and wesson forum, and it seems some people have had this problem if the mainspring was slightly angled or not tightened (not the problem in my case) or if the hand was not placed in the trigger assembly properly. I don't really want to remove the rebound slide to find out, but I suppose that could be the case. Well, I reckon I'll take it back to Briley and see what they say, and if that doesn't pan out then maybe back to S&W (where it probably should have gone in the first place).
