Ellie J. ★★★★★

Swapped out my factory adapter plate for this one and noticed the aluminum construction feels much more solid than the polymer one that came with my gun. The machining on the screw holes is precise, so the optic sits flat with no wobble. Painless install and now my red dot holds zero perfectly.

Timothy ★★★★★

Installed this last night and the fit is absolutely perfect—no wiggle or gap between the adapter and the slide. The machining is precise enough that my 507K sat flush without any filing.

Sophia ★★★★★

Finally got the adapter plate on my Gen 5 and the 507K sits flush with no wobble at all. The machining is clean and the screws threaded in without any fuss, took maybe five minutes to swap over.
