I recently bought a Kahr 1927A-1 tommy gun and have been kicking around the idea of putting the 10.5 in. barrel on it. Has anybody here done this before or know of a good gunsmith that knows how too? By the way, ive been reading all the problems about the Kahr Thompson Guns, but mine runs like a champ! Maby they worked out some of the bugs or I just got luckey.
