Git Gud (get good) or get [insert casual term here].
One of the two of us really likes mini reflexes on their pistols. The Five-Seven is outfitted with a Burris fast fire III. The sight is mounded via plate, and replaces the rear sight. No milling is required, however the slide will more than likely need to be disassembled and the rear sight mount fixed in place. But I digress, this reflex sight has a very crisp 3 moa dot with 4 brightness settings (auto, bright, medium, and dim). The automatic setting is useful for each situation I have tested. The glock 21sf is sporting a trijicon rmr with 6.5 moa. The slide has been milled down to allow cowitness with the suppressor height sights. There is no auto setting for bightness. Just "+" and "-" buttons to allow for the desired setting. Both pistols are a dream to shoot, and feel like cheating when shooting under stress.
