For those of you that are interested in the 22TCM9R Glock conversion barrel kit, the old style kit is currently available, for the Glock 19. I know folks are interested in these conversion kits because I got a huge spike of traffic when I last posted about it. As well, I got a few comments, too.
The old style will fit Gen 3 and below Glocks. I do not believe it will fit the Gen 4+ models, due to the change of recoil springs (the springs changed after Gen 2).
I’ll keep watch for the new style conversion kit and will post up if I see any for sale.
