I bought the AAP-01 a while back, but this year received an XT501 tracer unit for Christmas. Naturally, the first gun I fitted it to was my new pistol. However I've noticed that the connection between the outer barrel threads and the tracer unit threads appears to be loose. If twisted too far round, instead of the connection becoming tighter, the tracer unit slips and becomes loose again. On closer inspection, the threads appear to be a little messed up. I'm aware that replacement outer barrel threads are available, however would it be possible to rethread it with a tap and die set? I'll attach a photo
TIA
