My new P365xl rear sights stay on with a Holosun HS507k-X2 installed. Would the SOX10009 XRAY3 Super Tall sights co-witness or would they be too tall? — 2 Answers

The SIG SAUER X-RAY3 Day/Night Sight Set would be compatible with your P365 XL, but the front sight is .374" tall, and the rear is .417" tall. This would likely equate to at least an absolute co-witness, or possibly higher than that.

My 2022 P356XL has a factory optic cutout, not custom milled. I bought the SOX10009 XRAY3 Super Tall sights & lined them both up with the Holosun HS507k & the sights were too tall. The optic window was co-witnessed up to about 1/2 of the optics window or more. This was too much of an obstruction for me so I returned the sights & the search continues. If anyone has recommendations for a lower 1/3 co-witness with the same setup please chime in. Thank you.
