I too bought a red dot with the Browning logo and it works great. The Counter is very accurate and has held zero over several hundred rounds. Love shooting this pistol.
Recently bought UFX with pic rail for Steel Challenge competition. Installed Tandemkross trigger to control trigger reset, their "gearbox" to reduce trigger pull, Striplin charging handle. Trigger pull as purchased was 72 oz, after 300 rounds it was 64 oz, with gearbox now 48 oz. Had Vortex Viper red dot installed but was difficult to pick up dot quickly. Switched to the Browning with large window and larger dots and works great.
I bought a reflex sight for my Buckmark camper. Cheap one that looks exactly like Browning branded one.
