629-4 rattle

[Walton Feep]

I am new to revolvers so hence this question.

I just received a 629-4 Mountain Gun. It hasn't been to the range yet but I have tested it with snap caps.

When I raise and lower the gun I can hear a little rattle inside. It sounds like a piece is falling in and out of position. It doesn't seem to be an issue but since I know nothing about the internal workings, I thought I would ask the experts.

I checked a new 640 Pro I own and hear something similar but a lot quieter. Again I assume this is all normal since the 640 Pro has been to the range and functions well.

Thanks in advance.

Perfectly normal, that's the internal hammer block safety.

Thank you sir!

As posted that is exatley right.

Does it rattle when its cocked/hammer back?

Yes but the movement I am hearing is significantly less when it is cocked compared to when it is not. Cocking it definitely reduces the sound.

Just shoot and enjoy, your gun's fine.

No it's not.
It's the the rod inside the rebound slide that acts as a trigger stop.That's why he's hearing it less when it's cocked.

The 629-4 shouldn't have the rod inside the rebound slide.

The 629-4 shouldn't have the rod inside the rebound slide.

Really ??
All 3 of mine from the factory do as well as other N frames I have..

Took it to the range today and shot 24 rounds of .44 special through it with no issues. Very nice shooter. Would have done more but was also sighting in another gun which took some time. It will definitely be spending more time at the range. I may try a Burris FastFire III on it next time.

So why is it rattling around?
I just noticed it while cleaning my new 638-3 airweight.
I popped off the side cover to peek and the only think that can rattle inside is the "Hammer Block" (part #78 on the schematic in this post).

I dont recall it rattling when I bought it.
Is there any way to stop the rattle? I find it rather annoying.

Since my 442 has an enclosed hammer it doesn't have a hammer block, so no rattle. Some people remove it altogether.

I wouldn't recommend removing the hammer block, it's there for a reason. The slight sound it makes is only heard when you shake the gun up and down.

Quit shaking and you won't hear it!

I hear it also if I hold the gun and rotate my wrist.


This is really bothering me now.

 

[s&wchad]

I told my doctor that it hurts when I turn my head to the side and tilt my neck as far as it will go.

He told me to stop doing that and the pain will go away.

To make matters worse, he charged me $148!

 

[Remington788]

OK, I hear ya.
Just for the money I paid for it, I would not expect to have loose pieces rattling around.

I read in another thread to put a dab of grease on it, which keps it from rattling, though I wonder if that would get dirty.

 

[snubbiefan]

When they are very clean and not lubed...the rattle is prevalent. You can find them at gun shows that ring like a bell. They have had a couple of cans of carb cleaner shot all over them to clean them up, but they fail to lubricate afterwards. Your gun is almost too clean. You can drip a drop of a heavy gun oil down it there and stop it. No...I did not mean gear-oil or grease....just something thicker than Remoil or like product. It likely won't stop the rattle, but it may turn it into a less bothersome "click" if you shake it hard enough.

I'm not recommending that he remove it but rather that it can be removed without interfering with function.
I agree with you that it's there for a reason and one should never do anything that would affect the safety of a firearm and a little bit of a rattle can actually be considered comforting in that the safety features are intact and functioning.

Thanks, now my sides hurt...lol

I've never noticed it before so, of course, I had try mine to see if it was there. On both my 629-4 and Model 29, the noise is so faint that I have to strain to hear it. I guess that means that I have enough oil in them.

 

[Walton Feep]

It shoots fine so I am not worried about it at all. But as long as we are talking about our 629s, what are some recommended factory loads for target shooting?

I feel better after reading this too.

But Walton, you must post some pics of this new 686 for us to get us drooling.

Ahh ... you mean the 686-4 that I won on GunBroker I assume ... stalking me eh?

Won't have that in my possession for awhile as Maryland is a one/month state and I have one in the queue already. At least at this point I think I have all I need until we move to our retirement home near Mount Rainier.

 

[Walton Feep]

Here are the 629 and the 686 photos from Gunbroker. I'll shoot my own in the next few days.

Ok, so why exactly is it in there? The rebound slide pulls the hammer back when the trigger resets, and the hammer can not move forward until the rebound slide is pulled to the rear with the trigger. I tend to think that it is more of a "lawyer feature" than anything, and many gunsmiths do away with it when they preform a trigger job. I just watched Jerry Miculek's excellent trigger job DVD for the umpteenth time as a refresher while I did the first trigger job I had done in a while, and he even makes mention of the fact that it's a redundant piece. The only thing I can see it doing would be if someone dropped the gun and it landed on the hammer spur with enough force to shear off the hammer pin. IF that were to happen, then the hammer block would still lie between the hammer nose and the frame. Very unlikely circumstance but it MAY be possible.

With that said, they don't hurt anything so I do leave them in my guns.

My 627PC rattles ever so slightly, but I have to hold it up to my ear and shake it pretty vigorously to hear it at all. My 625-3 rattles a little more, but I still have to hold it close to my ear and pay attention to detect it. Can't hear it all in any of my J frames, or in my 66-4.

I put a big drop of Brownells Xtreme on it and the rattle went away.

Which is exactly the circumstance that killed someone in the US Navy during WWII. (Revolver was dropped from some height, struck the steel deck and the discharged bullet mortally wounded a seaman. The design was quickly changed just to prevent such dramas.)
