New To Glock
New to Glock. Not entirely sure which Gen this is. Bought used, had a Trijicon on it sitting on an optics plate and I wasn’t paying too much attention when they took it off but I think I did see two bosses in the back along with the screw holes.
Anybody know what gen this is and any suggestions on direct mounts?
Currently on a 4 hour drive away from tools lol
