M1 Carbine problem
Last time I took the gun to the range it was double firing. What causes this? Do I need to take it to a gun smith to get fixed? Thanks

Yes, you should have it looked at by a gunsmith. You could also run into legal problems if the wrong people see it doubling, which would make it a machinegun if its firing multiple shots with one trigger pull. 0 -

Did it double fire every time you pulled the trigger, or just sometimes? Did you notice, after it double-fired, was the hammer forward or cocked? Did you inspect the firing pin; did it move freely in the bolt?
If you are unfamiliar with firearms, then you'd probably do best to take it to a gunsmith. If you have generally good mechanical abilities, you could field strip it and start looking for the problem yourself.0 -
Are you shooting factory ammo or reloaded ammo? 0 -
And, who is the manufacturer?
Your question is the auto advice column equivalent of, "My car won't start, what's wrong?"

A stuck firing pin is about the only thing that would do this , could be bent or dirty. This would effectively turn it into a weapon that fires from open bolt, clean it , check the pin and test fire. Do not chamber a live round until its pointed in a safe direction because chambering may cause it to fire without the hammer droping 0 -
...is the hammer locking back on recoil..more than just a stuck fireing pin can cause your problem.... 0 -
amen, an under power load could do it also in theory 0 -
Ditto, kdixon.
and, not to hijack the thread on 2 points, but first: (Funny)
I was trying to come up with some 9mm loads that would run an Inglis Hi-power, a S&W 39, and a STEN.( I know, the STEN is a different system; blowback;)
So; I run the Inglis, fine; the 39, ok, but peppy.
Step to the STEN:, make SURE the sel. button is in semi-position, load 10 rounds, and.... ( can you see it coming?) light the fire and I've got a runaway gun!!!!
Holy Crap!! this is at a no full- auto club!!!
So when the RO's came up from the other range, I blamed it on the Inglis!!
I figured out that was too "soft" for the blowback gun's bolt to catch the sear. That MAYBE your issue.
Just fun to tell these old stories again.
Good luck with your carbine; I have 2 and you have been good advice.0 -
Thanks for the responses. The rifle is made by Underwood and I was shooting surplus military ammo.
It just happened the last time I was at the range and I was not shooting it. A friend was. Previous trips to the range I didn't have any problems. I don't know what the hammer was doing. I have not inspected the firing pin.
I'm new to the gun and have not had it apart for a good cleaning. Is there a good source of information to do this? I usually find some good videos on youtube.0 -
Separate from the stock and pull the bolt, flush with brake cleaner and a few drops of oil.
I have a feeling there is dirt by the firing pin.0 -
I think you have a worn sear or hammer and they are not locking up all of the time and causing the rifle to double. You may be able to take the rifle out of the wood, watch the action moving the hammer back and forth to see if the hammer will follow the bolt forward, it should lock up with the trigger pulled. If you cannot get the rifle to malfunction manually you will have to take the trigger group down and inspect the sear and hammer for wear and replace the worn part.
