Quoted: To make this take original USGI magazines, you must remove the Kahr magazine catch and replace the catch with an original USGI catch.
A M1 style Thompson will not take a drum magazine no matter what.
You need a 1919/1921/1928 model to take a drum magazine. |
I could've swore one time I saw a picture of a marine in WWII with a drum on his thompson and it had the horizontal wooden handgaurd and not the vertical one. Maybe they replaced the handguard or barrel with the newer type but had the older receiver?
I remember the caption specifically said something about a Marine breaks with coffee after a long night. Because he was drinking coffee in a trench somewhere in the pacific with his thompson next to him. |
Mil bought both kinds. The M1 Thompson was a simplified cheaper to make version of the original. With the M1 the ability to take drums was removed.
Generally, the 21/28 Thompsons had finned barrels, VFGs, and the leaf rear sight.
Generally the M1 had a stamped rear sight, smooth barrel, and horizontal handguard.
But like all other things, there are plenty of exceptions.
IIRC, the Army mainly had the M1 in Europe. The USMC had 21s from the Post Office, then 28s.
To the OP, stay away from Auto Ordnance.
