Watching TV and saw some footage from the 1920's and they quickly showed a 1911 with a tommy gun front grip mounted in front of the trigger guard. Also had an extended barrel with cuts on top for compensation.
M1911/Gov't Mdl Aftermarket Full-Auto and or selective fire modifications with the forward mounted 2nd Grip were made and offered by a few Gunsmiths in the 1930s, and Colt also experimented with them. They usually had long extended Magazines, Cutts Compensators, slightly longer ( or even much longer ) Barrels, and sometimes a Shoulder Stock as well...these in .38 Super or .45 ACP.
From books I have read on John Dillinger, Baby Face Nelson etc. there was a gun dealer/smith in San Antonio Texas that supplied a large number of outlaws with semi auto's converted to full auto he also put a fore grip adapted from the Thompson. From what I recall Dillinger had a Colt 38 Super semi auto that had been converted. I think the gunsmith was Hyman Lebmann or something like that.
Here's a copy of a thread I posted here couple weeks ago:
Recent mention of 1911 Full Auto sent me back into my dusty archives.
There was some activity on this forum couple years back and some of my
info is from there. When it started I don't know but it was full blown
in the mid-1930s, with Dillenger and Babyface Nelson using them. The
maker was found to be a Hyman Lebman of San Antonio TX, later
prosecuted but not convicted. Colt & others were experimenting with 1911 FA. See pix.
Never interested in full-auto, I had a couple brushes with the subject
of possible interest. First I had a Chinese .45ACP C-96 Mauser I
tried to shoot with conical rounds, it wouldn't feed. Put in half mag
of old hardball and fired. I didn't realize it went full-auto till it
wouldn't fire again, empty standing open, disconnecter fault. Second
I bought a Colt 1905 .45ACP that had a piece sawed out of it with mods
I think intended for full auto.
It is possible to disable the 1911 disconnector in a few minutes with
a Dremel. Whether it would be reliable full auto I don't know but the
mods in the 1905 seemed intended to slow down the rate of fire. I
never figured it out because some parts were missing. It had a mod to
the barrel link, a little rocker that reached down to the trigger and
a roller installed on the bottom of the trigger to ease its movement
in the TG. Looked like the piece sawed out of the frame was for
access to its innards for adjustment. Wear on the parts looked like
it had seen quite a lot of activity. I repaired it, putting it back
to a collectible 1905.
If anyone is interested, I have a long write-up on it, PM me with your
It is possible that the work on my 1905 could date back around WWI.
A 1905 would have been obsolescent then and a typical piece to use
for development, its innards being identical in function to the 1911.
Argument against post WWI is that the 1905 was scarce in face of scads
of 1911s available for $5-10 surplus.
We will probably never know but it's an interesting
Yeah, damn shame about the 'poison pill' the anti's put in the Gun Owner's Protection Act, banning any new production of full auto stuff, and driving the price of existing guns right out thru' the roof. Inflation has made the $200 tax stamp fairly affordable, and it would be fun to have a rock n' roll something. Got to shoot a '28 Thompson, and it was about as much fun as you can have with your pants on.
