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.

    Bought this slide for my MR918 but did not notice that the MR918 slide is different from the MR920 slide. This plate will not fit MR918 slide since this slide optic cut is not flush and has 2 post specifically for the RMR or holosun 507. But on the other hand C&H had Great customer service

    The screws are the correct thread pitch for Shadow Systems pistols (apparently the screws provided from Holosun are not correct for the Shadow Systems).
    Plate fits tightly to the slide and is obviously high quality.
    Holosun 509T fits great to the plate.
    Only downside is that the factory Shadow Systems iron sights don’t cowitness to the 509T, but this is NOT a shortcoming of the CHPWS plate – rather a necessary occurrence due to the nature of the 509T being a closed emitter optic.

    Highly recommend this plate from C&H – I am very happy with it.

    This is the EXACT mount you need if you have any of the Shadow Systems slides for the MR, XR and DR models. Compared to the OEM 509T mount, this is a FAR BETTER system. It both takes up all the space front to back in the SS slide cut and it provides a slightly wider ledge for the 509T basically creating a cradle for the entire bottom footprint of the 509T. It is a far superior mount compared to just using the mount that Holosun supplies with the 509T.

    I do want to note that it doesn’t place the 509T low enough vertically to make use of any level of co-witness with the SS iron sights. You will still need higher suppressor-level irons if you require a co-witness. To be clear, you can not see the SS stock irons at all with the 509T mounted.
