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.

    Placed this optic on my sig p320 vtac and love that I can co-witness through it with the irons.

    The optic is perfect. Rock solid and just as advertised. Ordering from CHPW however wasn’t the best experience I’ve ever had. The cheapest shipping available was $20 for 2 day air. It came to my house a week later or five business days. Which is fine I didn’t mind waiting but if I must pay for 2 day air I expect to get it in that time period. I reached out to CHPW and never heard back. My plate and optic are great, the service from CHPW was mediocre.

    Another great Holosun reflex sight. This is my third Holosun from C&H a previous 509T-RD and a 509T-GR-X2 along with the excellent C&H plates. Everything fits perfectly and the sights work great right out of the box. I only had to add a couple of clicks of windage to the 509T-GR the other two were factory zeroed and no adjustment needed on either my Walther PDP’s or SIG P320X5. C&H customer service is always super helpful and extremely friendly and knowledgeable. Prices beat everyone else and shipping is fast and reliable.
