I recently bought an M1 Garand and absolutely love it! However I had a problem today while shooting. I had a couple of misfires and when I looked at the round it only had a slight indention on the primer. This seemed to happen every 3 or 4 rounds, then I noticed that with each misfire the trigger guard was slightly unlocked, I would snap it back into place and it seemed to work. Has anyone else ever experienced this? Is there a quick fix for this or should I take it to a gunsmith? Thanks!

Either the wood on your stock is compressed or the lugs on the trigger guard are worn. Either one is fairly cheap fix
Are the lugs round or do they have a flat spot? This one is only very slightly worn
If flat replace the trigger guard

[tmrami]

is this what you are talking about? Does this look too worn?

TMRAMI, yours looks flat. I think replacement is in order. Parts are available at gun shows, online, or from your buddies here at the forum. If you have access to another trigger group, try that one and see what happens. Then you will better know what's wrong.

They are flat but dont look bad enough to be popping open on ther own. I would say it may be a combination of worn lugs and compressed wood on the stock.
I would replace the guard and see how it goes, you may need to shim the stock under the trigger guard also

I agree with Orlando in that the lug in the pic is not too terribly worn. What does the hook look like on the back of the trigger guard? If it is good, I'd take the trigger group apart and then using padded channel locks or a vice, I'd squeeze the trigger guard together to tighten up the fit and keep it from coming undone during firing. If the hook is shot, then you'll need a new guard. Is there tension on the trigger guard when you close it? If not, as Orlando pointed out, you probably should try to shim the stock and that, combined with compressing the trigger guard, should take care of the issue. For good measure, I'd strip the bolt and check the firing pin to make sure it isn't broke. I think the issue is your trigger group unlocking during recoil and then the next round doesn't fire, but it should be stripped and checked anyway when you acquire a new rifle - if you haven't done so already. It's a good time to check headspace as well.

One thing that I forgot about is that sometimes a new stock can cause the trigger group to come unlatched during firing, if the guard is bind on the angled cuts on the inside (in the area labeled #4 on the link). If this area is causing binding, it will need to be relieved on the stock. Check out the link. You can click on the photo and it will zoom in so that you can read it.
