I would buy the Holosun 507K X2 again!


Purchased with a slide cut on my Glock 43X by the Glock Store. Slide with mounted Holosun 507K X2 returned to me on time as the Glock Store committed. Easy to site in the 507K X2 and works great on my 43X EDC. Could not be happier with the end result. Always expect the Glock Store to deliver on time with the best quality and they never disappoint!
