S&W 64 Broke

My Model 64 broke last night...while dry firing I noticed that as I tried to manually cock the hammer it felt like something was binding and eventually would give. Then while double action trigger pull, the cylinder would rotate, but the hammer would not cock, it would sometimes after the third or fourth trigger pull.

Anyway, gun was shipped to Smith today. I'm just curious if anyone who is familiar with how the rove lovers work, or have tinkered with them , might have a clue as to what is wrong with mine? I'm kinda bummed, just got this 64 and didn't get to shoot it.


Thanks

My bet's on a binding rebound slide. A binding rebound slide would make it difficult to slide backward (difficulty in cocking the hammer) or fully forward (re-engaging the DA sear).

Could be a bona fide breakage, or some errant piece of grit in the perfectly wrong place.

Mr.Borland,

Thanks for the post. I know what the rebound slide is, but not what it does... I've been looking at the sticky on here and someone also posted an animation of the inner workings of the revolver.

The rebound slide is spring-loaded, and does 2 things: It resets the trigger to its fully-forward position. Secondly, at the end of its reset stroke, the little nub on the top engages the little nub on the bottom of the trigger to "rebound" the hammer from its bottom position. The rebound slide makes it impossible for the firing pin (through the hammer) to contact primers if the gun is dropped.

It may take a bunch of watching, but the animation should show you that the trigger must fully return & the hammer fully rebound for the double action seat to engage.

We could speculate all day because there could be a number of reasons, such as a broken hammer or trigger stud (the pins those parts rotate on). Or if the trigger pull felt especially light the mainspring strain screw might have been shortened or backed out too far. Besides the rebound slide that's been mentioned somebody might have done a questionable action job.

You did the right thing in returning it to S&W, because they will completely inspect the gun, and then fix any and all problems that they find.

Thanks for the post... I was thinking the same thing, that Smith would go over the whole gun...I'm getting hooked on these model 10 type guns,well all wheel guns lol

Oh dear... I'm so sorry to hear this. But fortunately you have a lot of versions to choose from, since they've been in continues production since 1899. :cool:

You could have broke the hammer stud. Too much down pressure on the hammer will do it.

Is your revolver new or used? If it is used I'm guessing we now know why the original owner decided to sell. If it's new, well, that just stinks all together!

It's used....I checked it out to best of my ability, but I'm no gunsmith. I guess that's the risk of buying these used old guns?

Of course there is some risk when you buy a used gun, and sometimes a new one too. But I have found that the risk is usually worth taking, because unless the gun is a real beater the chances are that the used one will turn out fine.

In the case of S&W lockwork, most repairs can be made at relatively low cost, and sometimes no-cost when only an adjustment is involved. What apparently happened to you seems to be an exception to the rule, but don't jump to any judgments until the company reports on what they find. If a part failed because of a material flaw or sub-standard workmanship they may fix it at no cost to you, in which case you will come out the winner. You'll just have to wait and see.

Fuff,

You're absolutely right.. Stuff does happen. I had a 1955 model 15 that I traded for my recent model 19.... And it was smooth as butter. I bought my one and only Performance Center gun this Februrary. A 627PC ,awesome gun, but it broke after about 30 rounds. Smith fixed it in less than a week, I think it was 4 days at absolutely no cost to me, that's service!
