DRY-FITTING DISCLAIMER:
At C&H Precision, our products are designed and manufactured to meet tight tolerances. Installation can be affected by variations in your plate, hardware, optic, and firearm tolerances. For safe installation and to prevent potential damage to any component, we advise dry-fitting all parts before a full installation. If any problems arise during this process, please reach out to our Customer Service via our contact portal.
­
IRON SIGHTS DISCLAIMER:
When making aftermarket firearm modifications, factory components can often become obsolete, particularly when mounting optics on the slide, whether through direct milling or using a plate. Achieving the correct height for low co-witness iron sights depends on factors such as the firearm type, mounting plate, optic, and slide cut. For assistance in determining the appropriate iron sight height for your specific setup, please contact our Customer Service team through our dedicated contact portal.

  1. Troy Fortmann (verified owner)

    Pricey but the best way to secure a 507K to the factory XDm slide cut. The plate width matches the 507K perfectly and is narrower than the factory plate so there less snag possibility. The plate is about 0.02 inches thicker (taller) than the factory plate. Depending on after-market backup iron sights installed, this could be a factor but works fine with Trijicon Optic Height Sights. Overall, definitely worth the cost! value

    Well, this experience took a ride around the block. The plates showed in stock when I placed my order but alas my luck held true. I received a call that there was a problem with the plates that were in stock and they were making a special run to fill orders. I was asked for permission to cerakote the plate rather than anodized to shave a few weeks off the turn around time. I gladly gave permission for this.

    The plate finally arrived and fit & finish are great. The plate fit perfectly to the handgun and the optic to the plate. I highly recommend C&H Precision!

    Like the other two reviews below, the channel for the right t-nut was not milled correctly. I ended up taking a tiny bit of material off the right t-nut to make it fit. Once you can get the t-nut to fit, installation is easy and everything fits like a glove. For the price and a company with “precision” in their name, you would think the small details would be important.

    Like superjas74 my plate was milled incorrectly. I used a rotary tool to extend the channel of the right T-nut. After this it fit correctly. Also it would be nice if the parts were labeled is some way as it is not obvious which screws are which. Other than this it works as expected.

  5. superjas74 (verified owner)

    The underside of the plate wasn’t milled correctly, had to end up sanding off a partial end of the right T- Nut to get it fit properly. After that was done fit like a charm. If milled properly it’s an easy and quick installation.
