Quoted:
Has anyone tried out the new semi-auto Tommy Guns offered by Kahr Arms? They look nice, and MSRP is about $800.

Since you asked for input, here is mine. Any (full auto or semi) ones manufactured by Kahr Arms suck. Is this from first hand experience? Sorta. Most of the experience is from reading other posts. Here is one particular web site specific to the Thompson: http://www.machinegunbooks.com/cgibin/ikonboard/forums.cgi?forum=1
This site contains info on both full auto and semi.
Some experience has come from witnessing others attempting to use their full auto version with numerous problems.
Also if you check www.gunbroker.com you can always find a ton of these from Kahr Arms for sale. Why do you think?
If you really wanted one, at least pay the $200 to have the appropriate (shorter) barrel placed on.
Also, do a search on this web site as others have asked the same question as you. You may find some addition info.
