Colt .45 Full Auto ???
Does anyone have experience with Colt Autos going full auto?
I bought a much-modified 1905 Colt 45ACP that had its interrupter filed off flush with the frame - where it could no longer function. Other mods make me believe it was to make it full-auto. The frame is so modified that I did not consider it safe to fire it and check it out.
This could apply to most any the Colt auto from 1900-1911 because they are alike design-wise.
I replaced the frame to have a legal and functional pistol.
Comments, thoughts, experience reports appreciated. Thanks
Edit This was no bubba job. It showed high talent and work requiring sophisticated machine tools. Reminds me of a 1900 with no s/n, new condition I had in the shop showing work toward developing the slide lock that came out on later models.

The 1905's had factory brass firing pins. These would not be conducive to full auto firing.
A stuck steel FP is usually the reason the 1911 series goes wild.0 -
A BUBBA trigger job is a cause also [V][xx(] 0 -
+1 on the trigger job. MANY years ago, before i got old and a little smarter, I did more work on lightening the pull on my 1911 than I had any right to. Fortunately I was outside and not at the indoor range when I pulled the trigger on a full mag. Shot 1 hit the target and by the time the magazine was empty my arm was straight up the air. Not an experience I care to repeat. The only good thing was that I hadn't touched the frame, just the hammer and disconnector; both easily, and quickly, replaced. 0 -
In 1960s our base pistol team had an indoor range and Gold Cup 1911s: There were a number of holes in the ceiling from these things doubling and tripling, but never seemed to go a whole clip full. 0 -
in '53, on a bet, I converted a 1911 to full auto via a trip mechanism operating through a small hole in the frame.
It was an extremely dangerous device when arming.
After winning the bet and firing a few hundred rounds, I dismantled it and put standard parts in it because it was too dangerous to the user.(it went off once while arming)
Once the trigger was pulled it emptied the mag at about the carbine rate of about 650RPM.
You learned to lean into it at the first round and the pistol kept pretty much horizontal. I have a photo I may post of it firing.
It's faded by now but once you could see two or three cases in the air.
It ended being given as a favor to a USAF Captain, brother of an Army buddy, who flew a General around and visited our unit.
He wondered at the hole in the frame but was assured it didn't affect the functioning.
Anyway, my box of war trophies were remailed from Alaska.
Sadly they are all gone by now.0 -
Thanks for replying. Confirms Colt autos can go full auto, which is what I needed to confirm my theory as to purpose of the 1905 mod. I don't think it was intended for that particular gun, rather a development experiment for possible application elsewhere. It cut up a great gun and one high up in the cost for its time.
My only experience with full auto in a handgun is in a .45ACP Chinese broomhandle. It had four rounds in it that went so fast that I didn't know it. Wondered why it didn't shoot again when I triggered, then and saw the bolt standing open. No noticeable rise from recoil and wasn't aware of the sound.0 -
Are you sure you mean a Model of 1905? That is such a rare gun that I am amazed that you could find a REPLACEMENT frame! Just HOW was the frame modified that required replacement? 0 -
Recently I went back to a man I had been getting 1902 38ACP parts from for years who reported all he had left was a frame 'in-the-white' never on a gun. When it arrived it was for the Colt Model of 1905, .45ACP. I'm into 1905s too and had never seen any parts for sale before. I kept it.
One of life's great coincidences, next day, auction had this 1905, about 50% condition but with a piece cut out of the frame about half inch wide just behind the rear barrel pin, left side.0
