White one is chambered in 9 and uses Glock mags. Interchangeable with my every day Glock. Need a jig and a router to mill. I posted another pic of how it started. I got the lowers from a small independent shop where I know a guy but essentially when I got them they had no trigger well or holes for the trigger/safety. I have a job, route out the well about and 1/8 at a time and a few dozens passes. Then drill press for the holes.
