I'm like a decade late to the frame modding party but I did a thing today and just went for it . Single undercut, finger grooves deleted and stippled, accelerator cut and stippled. First time doing it and I think it turned out decent.
I have a bunch of Glocks, Sigs, HK, ect. I have to admit my Gun Co G19 is my absolute favorite. I can hit a 10” gong that’s 100 yards away up on a hill about 9 time out of 10. The rmr is great and night vision compatible. It shoots superb.
Just got my Glock 45 and installed all the goodies. Aimpoint ACRO P2, Forward Control Design optic plate, Surefire X300T-B, Radian Afterburner/Ramjet. Running OEM guide rod and polished trigger components. Will probably get a OEM NP3 - connector but the Gen 5 trigger actually feels pretty good as is
