Since I bought my rack grade from CMP many moons ago, I have developed a slight problem with my garand. At first I didnt think the loosness in the stock and the ocassional failure to fire were related but now I think they may be. When the action is out of the gun it functions fine, no issues. And other than a rough gas tube and a muzzle that has been hit to hard as steel cleaning rod its great. For some reason though when I put the action in the stock it refuses to catch the hammer on the disconnector when the trigger is held back the the action cylces. Now if you fire or cycle the gun and are not holding the trigger back with the action cycles, the sear catches the hammer fine. I haven't fired the gun since shimming stock to get rid of the looseness, but that doesnt seem to help the problem (I've tried shimming it ever way I can think of) though it has improved the fit.


Does anyone have any ideas on what hte problem could be? I think the stock must be warped or something, but I'm not sure. Is there any way to fix the issue or am I going to have to buy another stock?

Sounds like your stock  wood is rubbing against the trigger group somewhere. If the hammer is catching on the wood, the area it hits needs to be relieved.
You are going to have to find wear marks from the hammer rubbing on the wood.

With a the other issues you mentioned (muzzle dented, rough gas cylinder) it may be a good idea to send your rifle off to someone who can correct the issues. It will get all of the issues fixed and get you back to enjoying the mighty M1. A local gunsmith could probably do a light job of glass bedding your stock, fixing the loose fitting issue and correcting the fit of the trigger group.


This guy is selling some M1 stock really cheap. They have been repaired, but can show you the areas to fix on your existing stock.

I'll probly have it rebarreled at some point to and replace the gas cylinder at some point, but those really arent pressing issues as they havent really affected functionality (other then a bit of accuracy perhaps from the slight wiggle in the gas cylinder and the uneven muzzle wear). But the disconnector issue is more disconcerting, and while I have fired it safely so far, now that I understand what's causing the issue won't be shooting the gun until I get it sorted out. I'll look at the stock/FCG fit to see if there is rubing but I don't think that is the case. It's almost like the stock or at least the rear portion  is bowed or swollen slight causing the rear of the trigger group to be just far enough away that the sear can catch the hammer, but the disconnector can't.

Just as I thought the problem was the stock. The original stock was apparently warped or something. New stock did the trick. Unfortunately the "new" stock was far from it. But it should do fine until I pick up an actual new stock.

You can peen the splines to tighten the gas cylinder, this is very common.

When you get your new stock you may want to store the rifle with the trigger guard open so you do not compress the wood.
