tommy gun
I bought one of these last winter, after a couple of clips I realized the rear sight was falling off,one screw completely fell out before I noticed it, I went to Kahr's site and tried to find replacement screws but couldn't so I wrote their customer service department, they emailed me back the next day and told me to send them my address, with in a week I had 6 new screws and a small tube of lock tite, since the sight was loose I took it off to clean the oil out of the holes,once I got that far I went ahead and sanded the top receiver down and polished it, then cold blued it, it's still not the same as a real Thompson but it looks alot better, I also built a longer horizontal foregrip so it doesn't look like the barrel is a mile long. With good mags it fires perfectly,the drum never works well,but it looks really cool. Bob.
