Hey
Hey every bit of info out there on this subject points to the fact that they say just buying a new or used semi thompson is cheaper than all the changes that would be necessary in order for the BATF to consider it to be no longer a FA gun... Thats why you won't find much info on it. I have seen a guy that takes a semi auto 28 style model that is being produced to day that puts the Auto/Semi selector back in and makes it hold the bolt open for quick drum changes which is an awesome idea no more third hand tool...
You have four factors you would have to deal with in order to make it semi only.
1. Closed bolt operating only
2. Modifying it enough so FA parts could not be installed as in the 1919a4
3. The cost of the parts that you would be modifying are costly for an experiment
4. To SBR or not to SBR
All these things could be done but its the cost involved in doing them. How would you feel about cutting on an original trigger frame? One alternative would be sarco's cut trigger frames I think they only have them for M1A1's though. 80% receivers are available from
www.philaord.com. T&S manufacturing can put original markings and make a lot more of the surfaces more correct, but by the time your through you may be able to buy two or three new Kahr thompsons... It's all about what its worth to you and how far you want to take it... I for one would love to see some of the WWII thompsons back in action with maybe an ar15 trigger and sear setup could be possible they did it with the sten and some other sub guns...
This is a good thread lets keep it alive... Lets see if we can get some of those old sub guns back to the firing line...
