Yep, my personal best with a stock Glock is a 99. It certainly is close. Statistically speaking however, if you shoot enough you will occasionally get some of those high outliers. I just think that you are probably needlessly frustrating yourself if you are a no shit 95 shooter day in day out and can't figure out why you can't get over that plateau with consistency. "with consistency" being the important part. Yes, I have lucked into a 99 but I am more consistently a low 90s shooter most days.
IDK, maybe I need to experiment more with top shelf ammo. I am waiting on a new slide with RMR and KKM barrel to play with now, so I will see how that goes.
I will say that 25yard and out bullseye shooting has taught me more about shooting than anything else. I would even go as far as saying that 25yd pistol shooting has made me a better carbine and precision rifle shooter.
