    Installation Notes

    • Installation requires removal of the rear sight and disassembly of the pistol slide to access two screw holes underneath.

    • Professional gunsmith installation is strongly recommended.

    Exactly What I Needed

    Posted by Brian Joseph Turner on 11th Jul 2026

    Finding the correct plate for my specific model was more confusing than I expected because there are several different slide variations. Fortunately this one matched my optic cut perfectly. Shipping was fast, packaging was excellent, and all of the screws and hardware were included. Installation went smoothly and the optic mounted securely. It looks clean, feels solid, and has performed flawlessly so far. Definitely a quality product.
