The gun is on. I'm liking it. All the problems at once frustrated and confused me.
After I finely tuned the windage, which I had to do myself to get it done right, and should not have taken me as long, I remained high. I was hitting about an inch or so high.
Well I recently once again switched out another backstrap. I put on the largest sight. It seemed to correct my elevation. I put a whole magizine in a 3 inch target at 15 yards. That's certainly better than I was doing. I also consider it something to build on.
I still can more effortlessly shoot smaller groups with my other hand guns, but I atleast trust myself with my Glock and feel I will improve. I also learned alot about sights and people. I only trust myself from here on out to properly sight my firearms.
I'm happy I kept it. I wish my offline support took my concerns more serious.
Thanks everybody for your commits and suggestions.
