1911 double fired.

[N80]

I have a basic Colt 45 1911. Made in the early 50's. It has had, at the most, 300 rounds through it, probably closer to 200. My son was shooting it recently when it double fired. In other words, he was working through the magazine bang.....bang...bang and then bangbang......bang.

He says we was only aware of pulling the trigger once when it fired twice. To me it sounded faster than you could even pull the trigger twice.

Is this a known issue with these pistols? Is it a cleaning issue? I've only had it apart once but have cleaned the barrel a few times. I'm not a big pistol guy and generally prefer a revolver so I don't know much about autos.

It very unlikely that a 1911 failed in a manner that allowed it double fire. The only way to go into a another firing is either the trigger was inadvertently depressed or their was a failure at several components in the gun. A failure of this type wouldn't be intermittent it would be a pretty regular thing. Additionally, there's a finite time to the cycle, theres no physical way for it to be "faster" even if there was a failure in the manner you describe. The time to fully cycle the gun is mechanical and is what it is. If your gun is a series 70, then its possible for it to be slightly more likely. Series 80 and beyond pistols have another safety mechanism, the firing pin safety, that would also have to fail for the pistol to inadvertently fire as described. The more probable explanation is that he pulled the trigger again. The way to ensure that its not the gun, if your truly worried about it is to take it to a gunsmith and let him take some measurements of the trigger and hammer components.

Thanks. I feel fairly sure that from what you are saying he was just pulling the trigger at the perfect moment and it fired as soon as it was mechanically possible. I don't know why, it may have been a grip/recoil/anticipation issue. (And I realize it has a mechanical limit in terms of speed, but it was fast. Faster than what you typically hear even in competitions). Anyway, it seems unlikely that there is a major issue as we continued to shoot it without problem. Thanks again.

My son, 11, tends to double tap by accident on his 22/45. It has a very light trigger and the recoil often helps him double tap it. Hes learning trigger control to prevent it.

I can't say anything about what might have happened. I just wonder about a gun almost 70 years old, having only 200 rounds through it. possible corrosion or dust contamination on key components?

Keep us posted on what you find out. Glad nobody got hurt.

It can happen, just one video: Double Trigger/Full Auto Problem Fix/Solution for TM Hi-Capa Platform (HD) - YouTube

Are you confident he didn't double tap it? Did anyone ever lighten up the trigger pull for you? There's a lot of instances of it happening, but usually there's been a "gunsmith" smithing the sear. Measure the trigger pull empty and see where its breaking if you feel it could be light. If it is I'd get a look at the sear and hammer condition and see whats happening. People have lost digits having them go full auto racking the slide with a full clip, so I'd exercise caution.

No, its like-new. Still have the original box.

I'm sure an unsafe situation could arise if this persisted, but in this case nothing unsafe happened. In fact, the shot still hit the paper.

I've seen it happen on a few 1911s due to a slightly limp wrist on +P ammo. The light SAO trigger they have, coupled with the extremely short resets they're known for; it is relatively easy to have occur.

I've seen it happen several times in my former career. Debris can hold the firing pin in the forward position so when the slide pushes the next round into the chamber the pin strikes it immediately without the normally necessary trigger press. I once saw a full 7 round magazine emptied full auto by this phenomenon. the shooter thought it was kind of cool (after his heart slowed to a normal rhythm) but couldn't get it to happen again firing subsequent magazines through the weapon. Usually the recoil will dislodge whatever is blocking the firing pin in short order so it isn't something that is continuous.

Since the gun is a bit older with very little ammo having gone through it, It may just need a good thorough cleaning and lubrication. Ultrasonic works great for weapons that have been stored for long periods.
