Is Kahr the only company that makes Thompsons? Or is it possible and reasonably cost feasible to build one? I'm just looking for a semi-auto SBR. I've got some background in gunsmithing having taken some courses during the summer in Trinidad, CO; I'm going to spending my whole summer there in 2006. The thing is that the only time that I've spent with a Thompson was years ago when I was in Special Forces and even at that it was only in training. I've got no clue where to even start if I wanted to build one or where to get the blueprints to build it as a closed bolt semi-auto.
I'm also curious as to myriad of different models. Is there a good website that gives a breakdown with pics on them?
Thanks,
Robert
