I have had my M1 for over a year with no problems until today. I shot 48 rounds and about 5 times it double fired. What could be the problem? Also, my Garand doesn't close the bolt when I insert a clip, I need to slam it. I have heard this can be normal, but could it be related to my other problem? Thanks for the help. |

Does it do that when you pull the trigger and hold it back ? If your pulling the trigger and releasing it right away you may get a double bump fire. It happens to my son a lot. If it fires two with the trigger pulled you may have a worn disconnector. Try a safety test with the rifle empty. Cycle the action to cock the hammer and pull the trigger and without releasing the trigger cycle the action . The hammer should stay back and you should hear an audible click when you release the trigger , if you don't and the hammer has followed the bolt forward the disconnector may need replacing. |
foxherb53 gave you some very good advice. I bought a used M1A several years ago that would double and upon inspection it appeared someone stoned the hooks on the hammer a little too much. Replacing the hammer solved the problem. In addition to that, I would have to ask if you are using reloads with soft primers. The firing pin floats and it normally leaves a small ding on a military primer when a round is chambered. A softer primer could detonate. A few of the local guys shooting CMP matches using reloads with soft primers have had their Garands double on them. They solved the problem by using harder primers for reloading. Any way you look at it, I would not think it would be an expensive fix. I have to bump the operating rod handle in order to chamber a round on my Garand. It should not be related to double firing.

I was shooting with some friends and I never experienced the double fire myself though I clearly watched it happen. They were always shooting from the bench when it happened and I shot one clip standing with no malfunctions. I appreciate all the help so far! |
:( I tested this and I don't get that familiar audible click when the trigger is released. The disconnecter isn't a serial numbered part is it? |
This explains it all.... It is very common for the M1-M14 trigger system to double fire when a firm follow through on the trigger is not used. It is very easy, when firing from a bench, to hold the rifle loosely in the shoulder and "milk" the trigger as they would do with a bolt rifle having a single stage trigger. When the M1 fires it recoils into the shooters shoulder, bounces back out, and hits the trigger finger for a second discharge. Shooter error... no mechanical fault. When shooting from normal combat style, field positions, or from a bench with the rifle pulled FIRMLY into the shoulder and a solid follow through on the trigger is used....this will not happen..... unless there ARE some mechanical problems with the rifle. This is in fact exactly what you describe. It fires normally when shot from field position, but doubles when fired from the bench by shooters inexperienced with the M1.... but who probably DO shoot from a bench with bolt guns. Your rifle sounds perfectly normal...... NOTHING is wrong with it. Best regards, Swampy Garands forever |
Yep, the only doubles I ever experienced was when I bought a navy trophy worked over by Charlie Frazier and I was bench shooting doing exactly as the above poster said. I posted, recieved the info above and have never had another double with it since. |
It's either re-setting or it isn't..... If the hammer cocks and then fires when you pull the trigger it's re-setting and working fine. If it's not re-setting, then it can't fire again. Your description above of what happened the day you fired it describes a rifle with perfectly normal function. Best, Swampy Garands forever |
Aren't you supposed to lightly lube the top of the hammer? |
Yes, the top of the hammer is greased where the bolt rides over it when it recocks the hammer. The rest of the trigger assembly gets oil at all moving joints (pins, sear, etc). The hammer hooks and sear hold the parts in place by direct mechanical locking. If parts start "slipping", it's due to someone stoning the contacts incorrectly or heavy wear. |

An old trick used on the M1 Carbine by soldiers during war was to stone the secondary sear/disconnector to get the rifle to double when the trigger was pulled to the primary sear release. The secondary sear/disconnector mounted to the trigger catches the outside hooks of the hammer. That is the wear spot where your trouble most likely lies. When pulled to the breaking point, the secondary sear barely engages the outside hooks of the hammer. The wear spot is most likely on the secondary sear but take a close look at the outside hammer hooks to see if they are worn. It is almost assuredly the secondary sear/disonnector on the trigger or the hammer hooks. Good Luck! |
Lube will NOT cause in in spec trigger group to double. |
