Thanks for the suggestion Peter Kohler. I will reach out to Dan and see what says.

Thanks deerslayer, I thought I saw that the top was what had to be reduced. http://www.notpurfect.com/main/thompson.html#stick

Oh so the bottom of the round holes needs 1/10" took off and not the top? I'm sure glad I asked before I started filing on it. Thanks

Hello, I'm new to the Thompson world so please bear with me. I've looked on the internet about the Thompson semi-auto magazine modification. It seems straightforward enough, file off 1/10" from the top of the hole. But I'm able to install the auto mag (the weapon did not have a mag when I purchased it; divorce sell, long story) as is with a little force. Should I be able to even do that? It doesn't look like the mag release has been modified. If the mag is engaging the catch as is then I'm assuming it's sitting high in the receiver causing my jamming issue? Thanks for sharing your knowledge, Reviskeev
