Hs507k on 43x - Holosun HS507K Red Dot Sight

It took a while to get mine from OP then I had to leave it with my gunsmith for a few weeks so he could mill my slide and mount the sight. That said, it was well worth the wait. It fits the weapon perfectly, low enough where I can co-witness with the iron sights and flush with the sides of the slide. As with the other Holosun red dot sights that I have, it allows for faster target acquisition and more accurate shots. I’m looking forward to changing the battery using the side mounted battery tray. This beats the heck out of having to remove the sight from the slide to change the battery. Overall, a great addition to my favorite carry weapon.
