Hi Mad,
This is a great looking Glock Major 9mm, can you answer some questions for me:
1. How long is the comp and barrel together?
2. What recoil spring did you use, weight & make?
3. Why not use a Docter red dot milled into slide?
4. Are you using the Taylor Freelance Mag extensions?
5. What powder and bullet are you using to make major USPSA 165PF?
Brian also made my comp, I use a G22 .40cal here is the link;

DVC,
Mell
