One of my shooting buddies mounted a Holosun 507c mini red dot sight on his Glock 45. Over the course of a few months, I shot a couple of hundred rounds with it. My eyesight isn’t what it once was and I found I shot tighter groups with Glock 45 / Holosun combination. I wrestled with the idea of putting a Holosun on my Glock 17. Finally decided to give it a try.
Holosun released another version of the 507c with a green reticle called 507c-GR and I bought one from Atkinson’s. I took the optic and my Glock 17 to Allen Moore and had him mill my slide to fit. As expected, Allen did a wonderful job of milling and mounting.
The 507c models have three reticle modes, circle reticle, a dot reticle and a combination of the two. I found the circle looks round as it should even though I have an astigmatism in my dominate eye. The dot looks less than round. I like the green color reticule. There are other features with the optic such as auto off and shake awake.
