OK, I think I'm going to build an open gun for USPSA and GSSF. Give me some feedback on my project plans. 1. Start with a Glock 22 (1st gen.) because that's what I've got and I can shoot major in USPSA or download more for GSSF. 2. Add a KKM stainless barrel with Glockmeister comp. 3. Add a Glockmeister captured stainless guiderod. 4. Glockmeister competition trigger spring + Glock 3.5 connector. 5. Jpoint/Optima/Firepot optical sight. 6. Add some type of mag well. 7. Get a Safariland 007 holster.
