How to Choose the Right Handgun Red Dot Mounting System

You can also purchase a new slide or have a current one machined to anchor without adapter intervention. Rival Arms, a Texas-based firm with an enviable reputation for that service, explained, “We offer two different optic cuts, RMR and DOC. The RMR cut, as you can imagine, is the same optic cut as the Trijicon RMR sight and will also work with other optics that follow this footprint (Trijicon SRO, Holosun 507c, Swampfox Kingslayer, TruGlo TRU-Tec Micro RMR variant, etc.). The DOC refers to Docter Optic footprint/setscrew pattern, which is compatible with the following popular sights: Vortex Viper [and] Venom, Burris FastFire, etc.”
I’ve noticed that this is beginning to be a real problem in the gun industry, i.e., choosing the right mounting option for pistol sights.
Here is another interesting article, more detailed and much more technical, entitled Footprints/Mounting Standards on Red Dot Sights. I catalog this sort of thing just for you, the reader.
You’re welcome. Enjoy. Share thoughts.

Most of the people I know who are knowledgeable about red dot sights on pistols tell me that you are better off having your slide milled by a gunsmith who specializes in such things. That is the route I went and my RMR fits perfectly and has not loosened. Much simpler that having to use a plate.

Ditto on custom milling. Here in the Carolina’s, I’m a happy customer of Mark Mohr’s NCEngravers.com
I also highly recommend red dot training from the master, Scott “Jedi” Jedlinski of the Modern Samurai Project.

You will also find after-market milling places the dot a tad lower than OEM MOS slides from Glock. Don’t forget the Vibratite threadlocker cement on the fasteners, the slide is a violent location for electronics.
I use Boogeyman Custom in Tucson, AZ for slide work on my Glock fleet.
+1 on Scott “Jedi” Jedlinski; I have taken his training and it is first rate.

What George 1 said. I’m just sent a slide off to a gunsmith to have it milled out properly. I’m looking forward to the finished product.
Mr. Smith: Thank you for posting the article.

I have an RMR; slide was milled by Mark at L&M.
Stay away from Chinese optics. Buy stuff made in America.
