Curious about an RMR.

Well I for one have no idea what you young 'uns are talking about these days.

He's talking about a specific brand of miniaturized red dot sight on a pistol. It mounts on the slide.

Like this....




No, I don't currently. I am buying a Walther PPQ Q5 though.

I have two equipped with Trijicon RM02 sights, a Glock G26 and a Glock G19. Great for old eyes, very rugged, always on and self adjusting to light level, so no buttons to mess with. Batteries are supposed to last for 3 years or so, I change them once a year to be on the safe side.

I got mine several years ago. At the time, there were no other red dot sights that came close to the RMR in quality. There are many more companies producing them now, I can't say how they stack up against the RMR.

My 54yo eyes arent as pistol sight friendly as they used to be. I put this little .22 together with a cheap reflex sight. WOW, i can ring the gongs again like i want.


Im just curious if anyone has an RMR(ruggedized miniature reflex) mounted on their gun.?
What is it mounted on?
How do you like it?

I have 2 and love them. Makes a big difference in speed.

Did you have to get the slides milled out for mounting, or is there a way to mount them to a regular Glock slide. If milled, how much does that typically cost? I am at the point I really need something like this to keep enjoying pistol shooting and for home defense.

There are mounts that fit into the sight dovetail, but the best method is to have a milled slide- it sits closer to the bore, and you can use suppressor sights as back up irons. Of course, it also depends on the particular gun, some slides don't have enough material to allow it to be milled. If you use a Glock, another option is to buy a pre-milled slide from various vendors.

I had mine done by Mark Housel of L&M Precision: https://www.landmprecisiongunworks.com/services/. Cost varies by gun model and various options and starts at $145. I can testify that he does excellent work. There are a number of other companies that do slide milling, but I don't have any experience with them.

Another vote for L&M

You mean something like this?



This photo was taken the way you use them, focus on the target and look through the dot. The red "halo" around the dot is the flower I had aimed at.

I had a Fast Fire 3 on a Ruger 22/45, have shot rabbits at considerable distances. I put the sight on a Glock just to see if i would like it. It works well but I haven't used it enough to be very quick with it. The habit of looking for the front sight slows me down but I can see that it would be very fast with practice.

I have a cheapie mini-red dot on my Buckmark. I like the size and the lack of tube and turrets that get in my vision like a Bushnell TRS25 does on a handgun.

Fast Fire 3 on my PMR 30. Amazing accuracy out to 50 yards and more than acceptable at 100 yards. Does need to be zeroed after every 200 rounds or so.

I have the same thing but I can't get used to it. Years and years with nothing but iron sights has made my muscles memorize where the gun needs to come up to line up the iron sights, then I have to lower the gun about an inch to see through the reflex.

I've since taken it off because none of my other guns have a reflex.

Armored farmer said:

Yes, like that.
What is that gun , M&P?
I have a mil-spec reflex View attachment 778534 on my AR pistol. It is certainly quick handling. Both eyes open, focus on the target.

Yes its an M&P Shield .40, I have an identical setup in 9mm that I use for practice. The cost of 9mm practice ammo savings over .40S&W practice ammo paid for the gun fairly quickly, the second RMR not so much as it and its mount cost more than the pistol!

The Shield uses the same rear sight cut as the M&P series so I used an M&P rear sight replacing mounting plate. Its a bit wider than the slide as the Shield in thinner than the M&P, but its not a problem when carrying and helps give a good grip when racking it.

How has that Firefield sight held up? What did it cost? I'd love something like it that is well under the cost of the Burris Fastfire. I've returned all reflex type sights l've tried that cost less than the Fastfire as they didn't hold up well enough to get past the vendor's "satisfaction guarantee" time window.

Not everyone can use red dots effectively so that is why I counter the conventional wisdom of "buy once cry once" for these things and suggest starting with one of the "cheap" tube type such as the TRS-25 before dropping serious money on one.

I got that Firefield Impact Mini in a kit that has risers and 45 degree mounts for AR usage for about $55.00, if I remember correctly. It looks like Amazon is selling them for $43.00 at the moment. I never bought the Impact Mini to be used on anything other than a rimfire gun. I don't think it could handle a centerfire at all.

The first one made it through one range trip and still worked at for a while at my home, but one evening it wouldn't turn on anymore even with a fresh battery. So, I returned it to the Firefield importer for a replacement.

The replacement only has a few hundred rounds under its belt at this point and is still working. The battery cap internals are improved on the replacement and maybe that had something to do with the first one's failure.

One thing to know is that the Impact Mini doesn't have locking screws for windage and elevation. I used blue Loctite on the adjusting screws and so far it holds zero.

The main reason I bought this cheapie was to see if I liked using a mini-red dot before committing to something better made.

One thing for sure about the Firefield brand and their website is that they do not have combat grade products no matter how tactical they are trying to be. Airsoft or airgun would be about the extent of their dreamland.

Does that sight have lockable windage and elevation adjustments?

The Fastfire 3 and Trijicon RMR do not have locking screws they have solid click detects -- like on a scope, where the only "locking arrangements" are generally on external (uncapped) target turrets so they don't change accidentally during handling and transport.

Let me know how the replacement Firefield continues to hold up, if it does, for ~$50 I could see getting a few for some .22lr pistols

I've never had to adjust the zero on my Fastfire and RMR sights after sighting in initially and I have them on 9mm, .40S&W, and .45ACP pistols. I mostly shoot steel plates 10-25 yards don't find it worth adjusting them even when switching from 147gr 9mm to 115gr, might have to tweak them if I were shooting 2700 bullseye matches, but I'm not.

Biggest issue on the heavy recoiling pistols is the mounting a screws shooting loose (Loc-Tite to the rescue) but its why I quit buying ones with bottom mounted batteries.

some videos that the OP may find useful







open division win with RMR/CORE (local match)

What wally stated. The only thing I can add is at fifty feet (the limit of my local indoor range) with bench rest I can get inch size groups. If I don't think I'm getting that I'll readjust. My son will roll his eyes and tells me it's the operator (me) and not the weapon or the Fastfire which may or may not be true.
