My M1 rifle is intermittently having a problem of the trigger not resetting. The gun is cycling, extracting, ejecting, and loading ammo fine, but the trigger doesn't reset. So when I take my second shot, it's like having an empty gun that has already been dry fired. If I manually cycle the bolt, the trigger will reset, but the next shot it won't. Bolt locks all the way rearward after the eighth round and ejects the clip just fine.
I've been running it dry it winter because of this problem. Today (it was only 25 degrees, so not even that cold), I put some CLP in the op-rod track and on the inside where the other locking lug slides back and forth. That got it to where I could fire a second shot with no problem, but n the third, the trigger wouldn't reset.
I put all new springs in it last year (Wolf spring kit) so I doubt that is an issue. It seems to only happen in winter, but, honestly, I mostly shoot it singe loaded for NRA mid range prone matches in the summer.
As I see it, I have one of two problems: the bolt isn't going back far enough when fired (short stroking) or the hammer hooks aren't engaging the sear.
Is it possible for a Garand to short stroke to the point of not pushing the hammer all the way back, but still eject and load ammo? I would think if it was short stroking, I would also have feed issues. The fact that it locks rearward and ejects the clip on the last round tells me the bolt and op road are traveling fully to the rear. I field stripped it last year and cleaned the gas port and tube thoroughly and then measured the inside tube diameter. I forget the numbers but it was within spec. Is there something else in the gas system that can cause this?
I cleaned the trigger housing group thoroughly last year. Other than some oil on some pivoting parts (trigger pine, which I also replaced, and the trigger itself and where the hammer pivots) there is no grease or lubricant int here, especially on the hooks themselves. Is there something else in the trigger housing group that can cause this?
Pretty annoying problem.
PS ammo is PPU M2 Ball spec.
