I installed a new recoil spring in my 1928 West Hurley Thompson. It was 11.0 inches new, but now measures 10.5 inches. I was told that a new spring should be around 11 and 5/16 inches. I am getting some jams where the shell is pushed slightly forward in the magazine. These occur in both 20 and 30 round stick magazines. The actuator sticks about half way back. I have to eject the magazine and push the shell back. For some reason this doesn't occur when I fire the gun in "semi-auto" mode. I thought perhaps a new Wolff recoil spring might solve the problem? I don't get the jams when using a 50 round magazine, but sometimes the gun misses a round. The actuator will be stuck forward when there are still shells in the drum. I have to pull the actuator back to complete firing.

Hi: I have a West Hurley 1928 Thompson submachine gun. I have had problems with jams in stick magazines. The drum magazine works better, but the gun will stop sometimes and I have pull the actuator back to complete firing of rounds in the magazine. I have had lots of work done on this gun, but I am still getting the jams. I had someone else fire the gun and he believes that the trigger is too heavy and that it may be causing some drag on the bolt during firing resulting in jams. My question is this: Would a lighter pull trigger solve this problem? Are EZ pull trigger kits available for 1928 Thompson machine guns? Thanks.

My Thompson (1928 full auto - West Hurley - Auto Ordnance) generally feeds the first round, but sometimes will jam after firing a few rounds. I will find the top shell pushed slightly forward. I eject the mag, push the shell back and generally I can complete firing. I have mostly 30 round stick magazines. I did try my 50 round drum once, but it was difficult to seat properly in the mag well. I found that if pushed it all the way in that was too far. I had to move back slightly. I would think that the proper seat would be to slide the drum as far in as it would go?
