A year ago, this would have been great. .22 ammo currently cost half as much as .45, if you can find it. I'm having a lot more luck finding .45 at a price I'm willing to pay than .22 right now. Me? I'll pay twice as much for ammo to get the "THUMP.......GONG" than for "pop........ting" when shooting steel targets. There are .22 cal Thompsons out there if you want them.

Maybe a plug inside the magazine spring. I'm thinking of something like you have in a pump shotgun that would fit inside the spring & allow the spring to compress & expand without interfering. I think you'd have to taper the top & bottom of the plug as it would be free to move up & down when the magazine is not full. Either that, or secure the plug either to the follower or the base of the magazine & only taper the unsecured end. A less desirable option would be to make a false bottom that is spaced up the proper distance from the actual bottom of the magazine. You'd have to shorten the spring for that, & I don't like that idea nearly as much.

Problem solved! It just needed a good cleaning. I took it to the range this afternoon to try out my new 50 round drum. It ran flawlessly! The problem with the drum is that I burned a whole bunch of ammo very quickly. Sure was fun though!

Well that was simple enough. Everything looked ok. There is some play in the lifter, but I think that's due to the design. I cleaned & greased everything & got it back together. I can not make it hang up any more! Thank you so much for your help!

I think I've got it on disassembly. Sounds pretty straightforeward. I'll tear it down, clean it up & see how everything looks. And yes, pushing the trigger foreward will reset it. Thank you!

I've done a little reading & found the names of parts. The lifter is what doesn't always drop back down under the sear block if I ease the trigger foreward after firing. If I let the trigger snap foreward, the lifter drops down under the sear block like it should & I'm ready for another shot. The lifter is a little higher on one side & that's where it hangs up. THe springs seem strong. The photo was taken from the front, looking toward the rear of the lower. I have lightened part of the lifter so you can see it better. I'm not sure how to get the trigger assembly out.

I just bought my 1st Thompson! 1st time at the range I had a few fail to fires. I racked another round in & it would do fine for a while & then FTF again. While cleaning it I noticed a lever in the trigger assembly doesn't always fall back after the trigger is released. Oiling helped, but did not completely cure it. I noticed that it works better if I let the trigger snap foreward after each shot, rather than easing it foreward. It almost looks like a couple of strokes with a file on the end of the lever would fix it, but I don't want to ruin my new to me toy. On my next trip to the range, when it failed to fire, I would pull the trigger again letting it snap foreward. This seemed to reset the lever & it would fire the next time I pulled the trigger. I'm also thinking I may have a weak spring somewhere in the trigger assembly. I've never fired any other Thompson, so I don't know what is normal. The trigger seems to have a very long & heavy pull to it. Is this normal? Is there a fix, or will a tired trigger finger help save me money on ammo? lol Thanks, Mike
