1) look into optics before getting the slide milled, because once it’s milled there’s no going back. Also ask how he plans to coats the bare metal on the slide after milling it.

2) yes the 19rnd mags will fit just fine.

 

I'd look at the Holosun EPS, EPS Carry and 509T. Closed emitters is where its at.

 

"RMR" is Trijicon's nomenclature for its "Ruggedized Miniature Reflex" sight. See - Trijicon RMR® Ruggedized Miniature Reflex Sight | Trijicon®

Holosun wisely designed its sights to fit the RMR footprint.

You only need a plate if you have a Glock MOS model. Glock designed its MOS setup as a general purpose slide cut method to accommodate a wide variety of different reflex sights by using adapter plates. The appropriate adapter plate is fastened to the slide and then the reflex sight is fastened to the adapter plate. IMO the use of an adapter plate adds an additional failure point, as opposed to mounting a reflex sight directly to the slide.

I have my slides milled and re-finished (nitrided) by Jagerwerks.com and I've been very pleased with their work.

Good luck!

 

Trijicon and Holosun both use the RMR cut, so you will have some good options. I've had mine done at battlewerks and they did a good job.

If you cut metal, you kinda have to put a finish on it to prevent rust and other bad stuff. The nitride finish is a good idea.

 

I had one of my Sig's cut, fortunately they use stainless slides so the finish is optional. I have seen people just mask it off and use spray paint to cover the slide cut and protect the finish.

 

I’m fairly new to o red dots myself. My first experience was with a Ruger MKII with a rear sight adapter plate with the dot mounted on that. I had a hard time finding the dot for fast follow ups. Did a lot of hunting and was pretty slow with it. It was extremely accurate, and it really stretched the distances I could hold a very small group. As I got older, my eyes couldn’t focus on the sights and target at the same time like I used to. I was sold on red dots, but thought it would take a lot of work to get better.

I had my Sig P229 milled for a RMR 06. When I started using it I realized the height of the Dot made a huge difference. The deep cut on the slide with no adapter plate lowered the Dot to almost the same height as the regular iron sights. When I draw the Sig and raise it to eye level the dot just rises into my focus on the target. I don’t have to hunt at all, it’s just there. The dot is now easier for me then irons. It’s on the same focal plain as the target.

Im going to have my G27 and G29 milled for RMRs soon.

 

Sorry for the hijack.

The Glock slides I’m looking to have milled are very nice generation 3 with the frying pan finish. They still look new. Would the cut be able to be refinished while preserving the frying pan finish on the rest of the slide?

+1 for jagerwerks

rmr is becoming a legacy footprint. You can use the Trijicon or the holosun, but the future is closed emitter like Steiner mps, acro, or new batch of holosuns.

not saying you need latest and greatest, but technology trends should be a consideration when making permanent changes.

 

507k footprint is identical to eps carry, fyi. The eps footprints are the same. Holosun was smart so people didnt have to buy a new slide to upgrade if they had one previously milled for the 507c or k. Another vote for jagerwerks, they do a great job, just takes forever.

 

The mags from the 19x will fit the 45 perfect, I no for a fact because I own the 19x.
