I have a 4" m29 made in 1962. It shoots fine. I'm just getting concerned because I'm not sure of what I'm seeing. When the cylinder rotates as I pull the trigger back, it almost appears to still be turning slightly when the hammer begins to fall. If I cock the hammer, the cylinder aligns fine and there is no movement of the cylinder still not locked by the stop signaling the revolver being out of time. The primers from shells I've fired don't show signs of any firing pin dragging or anything. Am I worrying about nothing. I have another m19 that exhibits the same thing and it fires and works fine. It is an older revolver like this one too. Is this normal for older revolvers? Thanks for any help.

Doesn't carry up or DCU is when the hand does not rotate the cylinder quite far enough to allow the cylinder stop to fully engage. To check for DCU, unload the revolver, triple check to make sure it is unloaded and close the cylinder. Make sure the muzzle is pointed in a safe direction and slowly cock the hammer. When the hammer is at full cock,use the fingers of your other hand to gently rotate the cylinder. If you hear a click and feel the cylinder stop engaging your revolver has DCU. Perform this on all six chambers. The cylinder stop is supposed to fully engage when the hammer is back. Some recommend placing fired cases in the cylinder when testing for DCU but it will show up even with out the fired cases.

DCU is a problem and generally requires a larger hand fitted to the revolver.

Before replacing anything, thoroughly clean the cylinder stop notches cylinder stop, hand and cylinder stop windows in the frame. A build up of crud can cause all kinds of problems including DCU. Good luck.

Thanks for the reply. I have done that test and the cylinder does not move with the hammer back. It is locked up as it's supposed to be. I assume you're talking about the hammer all the way back and fully cocked. If so, the cylinder is fully locked up. I am comparing this to some newer revolvers I have where the cylinder basically locks up before the hammer is all the way back. The cylinder stops turning before the hammer is all the way back. On this revolver, the cylinder appears to still be turning or must stop right as the hammer gets all the way back and starts to fall. It just seems strange to me after using a newer one that locks the cylinder before the hammer even gets all the way back.

So, I guessing that if the revolver passes the test you outlined, it's in time and I should be ok. Like I said, it shoots fine otherwise.

Thanks again.

Ideally, the cylinder should come to complete lockup well before the hammer is all the way back when cocking single action.

From the sound of your last post, I would say that the teeth on the ratchet have worn down to the point that the hand can't push the cylinder all the way to complete lockup properly. I have had that happen to a few guns.

They can be peened by a gunsmih who knows how to do it, or you can have the factory replace the ejector star. Also, as stated above, you can use a longer hand or a wider hand to help correct timing.

If you decide to go with a new ejector (ratchet) - and you need blue steel, let me know. We have new ones in stock for M29. Thanks - Judge [email protected]
