My son recently bought a new thompson and brought it over and we had some issues. that disassembly button gets stuck and its hard to get it unstuck.its scored up the inside of the lower good from using a screw driver in the groove to get at that button the charging knob is so small its hard to operate and Ive read that he can get the ez spring kit that will fix that and also the bolt hold open mod to make sliding the drums in there much easier. First shots, it had 3 out of 50 ftf. in the drum and 1 out of the 20 stick magazine. the one ftf shoved the bullet back in the case after getting hung up.We had fun shooting it. I apologize if its been covered here before. its the steel receiver version. 1927 chicago typewriter. semi auto. im not mechanically inclined these days much so it would need sent off.Thanks for any help and suggestions.

Hi Rabbit, I feel your pain, sir. It took two returns to the factory to get my 1927 to be reliable. I had good success with the AO customer service. The ejector on the bolt had to be pinned in place by them to fix my issue. Regarding the force required to operate the bolt, it will loosen up with time. I was reluctant to change spring forces so I made a little tool for myself that allows me to move the bolt back and forth with ease. The big pin fits right inside that little charging handle. Since I am in CA, I have to have a bullet button on mine. The little pin on the back end of the handle fits into the hole of the magazine release lever. I attached a picture of the finished tool. I have detail photos of how to build it if you want to make one for yourself, or PM me and I will make one for you. I also made a little screwdriver out of 1/8 inch diameter cold rolled steel that allows me to get under the upper portion of the receiver without gouging the surface of the bottom receiver. Again, photo attached. I would also make one of these for you if you want, or do it yourself if you choose. No patent issues. :-) I found that it is a pretty long learning curve to get to know this firearm. For me, it was worth it. I say silent and heartfelt Thanks to all those GI's that carried this beast and the ammo that it eats. Even in the tamed down civilian semi-auto version, it is a formidable weapon. Every time I take it out to the range, I get at least one visitor that has questions, and they always leave with big grin after emptying a mag or two downrange.

I have the EZ springs in both my 1927A1 and M1 Thompsons.  They are both Semi Auto and have been done on a Form 1 to make them SBRs.

The EZ springs are not going to hurt the gun, but they will add to reliability and make it much easier to charge the guns.

 

As far as take down, there is a small modification to do to the receiver so the gun can be taken apart without tools, search the forum, there are detailed instructions, in a nut shell, you just shorten the rails on your receiver by about 1/4 inch, it can be done with a mill, a dremel, or hire Dan Block to do it, he can also install the EZ Springs for you and polish the bolt to get it running right.  He does all kinds of other modifications, contact him and fine out how your new Tommy Gun can look just like the real deal smg with a little love and care.

 

My 1927A1 has a bolt hold open mod, done by PK, I am sure that Dan's is just as good, and worth every penny when you lose that silly little "third hand" that you need without it to lock the bolt back.  Plus it makes your gun look better as it uses a selector switch and mimics the SMG better.

dan did three of my thompsons.    2-27s and a m1,     all have ezpul springs, bolt hold back mods on the 27s, plus the mag catch mods to use the usgi mags...  and removable stocks.    my west hurley is so easy to cock you would think its  fa.    very smooth and runs like a clock.   I run blanks through mine for ww2 reenacting most of the time so I run the atf approved short blank fire barrel that dan did the quick change mods on.     hang in ther .   youll get the bugs worked out.

In addition to the other things mentioned, Dan Block also checked/reamed the chamber on mine to TSMG specs. I can’t directly PROVE that helped, but mine runs REALLY well, with almost no jams/FTFs/FTEs.  Just a sore thumb (and wallet) from loading emptied mags over and over.

 

Fun!

Got the ez spring kit in it and its binding up on the magazine now. bolt gets stuck on the top of the magazine and will go forward, just needs pushed. also, noticed a disconnecter popping out and rotating on the pin that holds it in, i had to flip it back in place.is it supposed to do that? I will have my son get ahold of dan.I have bad arthritis and dont really tinker on things these days but do enjoy the time. thanks forall the help.im sure itll run again.

Tennessee,

 

Get yourself a mag loader. Makes life a lot easier, albeit more expensive. One of the list members makes them out of wood. Beautiful pieces. there is a less expensive alternative made by RAE Industries.
