Too long for OPF-G, RMR plates, but ok with OPF-S, RMR (Staccato).

OPF-G, RMR is the same thickness as factory Glock plates.  We thought about making it thicker, but it'd mess up some backup iron sights, but mostly because it's unnecessary.  The extra thickness and the consequences that come along with a thicker plate are not justified, we'd get at most 1/4 more turn out of the screw.  Existing plate and 6-32 x 3/8 screw combination meets minimum thread engagement, anything beyond that is irrelevant.

Extra thread engagement doesn't equal better plate reliability if the plate is loosely toleranced, can't hug the sight tightly and prevent it from moving.

The idea that more thread engagement past minimum thread engagement is better is wishful thinking.

To wit, OPF-G, RMR and Glock's OEM RMR MOS plate use the same screws.  Whereas one is prone to loosen and eventually shear screws, OPF-G, RMR has never had these problem.  The difference is a design that can hold the RMR immobile, tight tolerances, and material.

None of these can be compensated by thread engagement.

Finally replaced my RMR’s battery after almost 2 years. Plate to slide screws are still exactly as they were when first installed. I’ve seen 3 pistol dots fail in the past 2 months because of screws loosening or the dot becoming damaged because of bad mounting choices. Glad I went with an OPF on my and my fiancé’s G45.

I stumbled across this thread again last night after seeing it many moons ago before it took off.

I have several MOS glocks, but have not outfitted them after experiencing trouble with the factory plate mount system.

After crawling through some of the pages and “discovering” the Forward Control plate system I have decided to complete all of them this summer as a project.

I have some preference questions regarding sights for co witness. I see some people prefer the blacked out rears vs the tritium. And one individual stated he has become ‘fond’ of the tritium rear and front. I am considering getting both to try out. To the people that like the full tritium setup can you explain the advantages it offers in your opinion? In low light condition does it feel too “busy” or distract your eyes for target acquisition?  Do the white dots on tritium sites have any negatives or distractions during the day or when using a flashlight in dark circumstances? I know that trijicon night sites are brighter than Ameriglos, does this have any marked or noticeable impact in anyones experience or preference?

Also, how tall is too tall for the site height? What is the perfect combination for pairing with the dot? I am completely new to RDS on pistols and will be mounting RMR and SRO.

Appreciate the info and knowledge. Looking forward to completing these as a new project.
Thanks in advance.

The red dot would be on all the time when you're carrying it, the backup sights are just a backup in case the battery went dead, or the sight went dead.

Some like the backup sights to be full fledged sights as if the red dot weren't there, many prefer blacked out sights.  One benefit of blacked out sights is they can be lower in height, as there are no tritium or dots to line up.  Sights with tritium or dots will need to be slightly taller, or the dots could be partially masked on the bottom of the sight window.

For RMR, GL-429 (no tritium) is very popular if you don't need/want tritium.  GL-811 (front tritium, blacked out rear) if you want a front tritium.

I would say going close to 7500, if not more. It’s been rock solid for me and I have another plate on my fiancé’s G45 as well, though it’s sporting a Holosun. I’ll probably pick up another plate in the near future to mount an EFLX.

Come back with show and tell after the summer!  

My Agency requires tritium.  So my personal carry guns copy that.  Full tritium shows up in complete darkness.  You never know when Murphy shows up.  If you are threat focused, the other concerns won't matter as the dot hovers over where you intend to shoot at.  When you use a WML, the tritium washes out.  You should use it for identification and then off.  It is a bullet beacon.    Have both Ameriglows and Trijicon.  They are the same.  Ameriglo has many more options.  They also are slightly wider up front in the slot to prevent movement than Trijicon.  You should also use a thin brass sheet under the rear sight as a shim as those are easily knocked out of alignment.  The SRO will have a better field of view than RMR.  There is however, one spot on the hood that if hit with enough force, will shatter the lens (i.e. running into a door knob or table ).

I had a 19 with the suppressor height Trijicon full front and rear night sights with the RMR and a weapon light.  One night I was outside in a very dark area of the yard and when I activated the light and looked through the RMR the dot was completely overtaken in brightness by all the night sight dots.  At that point the RMR was basically a window framing my night sights.

On my 45 I went with Ameriglo suppressor sights, as they sit slightly lower but are still visible through the RMR, with tritium on the front only as I wanted some form of night sight, just in case.

Yes it was in auto mode but that is where it defaults to after a certain amount of time.  I could brighten but it will go back.  I elected to reduce dot interference instead.

Did I make a mistake?

So a while back I decided I wanted a P2. Couldn’t find one, so patiently waited.  During this time, I thought milling a slide would be a pain, and decided to sell my g19/4 for a g19/5/mos. Well, came across a P2 today and snagged it… and came back to this thread for plate advice.  Looks like FCD is a no brainer- except now I second guessing that I should have just milled the slide to begin with.  

My old g19 went to a buddy who I’m sure would swap me back… but then I’m on the hook for 2 transfers and a slide milling.  Soooo… am I overthinking this?  Should I just buy a FCD plate and call it a day, or rewind time, open up my wallet, and mill and direct mount?  

(My main reason for buying a P2 is to be proficient when my work swaps us to acros this fall.  I learned my new work gun will be milled.  Consider my personal Glock/p2 a trainer for that transition)

MOS is the way to go.  Disregard that we make plates for them, I'd still say the same if we weren't in the plates space.

If you had your slide milled by a competent and honest shop, the best outcome is it works for the optics for which it's milled, and the installed height of the optic may be at most 0.1 lower.

You lose the ability to use other optics except for sights that happen to use the footprint of your milled slide, it's equally important that their dimensions don't differ drastically.

Speaking of footprint and dimensions, I continue to see folks reference terms that are not interchangeable, this adds to the confusion for folks looking for a pistols optics and plates solution.

1. The term "footprint" is very broad, it doesn't necessarily include dimensions which to plate makers like us, are as important as the lug diameter, height and spacing.

2. Backup sight heights.  Suppressor height sights don't mean optics compatible sights, sights height will vary depending on the optics and pistols they go on.

Re: ACRO, I think folks should look at our RLB (reinforced locking bar), and the upcoming RBC (reinforced battery cap), both worthy upgrades to the excellent ACRO P2.   Both were users requested development and much needed enhancements.  

We work at the wonderful folks at Aimpoint, they are aware and happy to see RLB and RBC

RE: RLB, there are several reasons for it.  We're friends with Aimpoint and must tread carefully, we've developed products in support of Aimpoint, this is one of them.

It's machined in 4130 and will not bend.  On top of which, it was designed to address a specific issue that can happen sometimes with P2, give us a call and we can discuss in detail.

My brother from another Mother!

Took delivery of my FCD RMR plate today (just took delivery of my spank'n new G19.5 MOS yesterday) and can say, without a doubt, the OEM MOS plate is hot garbage. But everyone in here already knows that.

Test fit plate to slide, no issues. Test fit HRS RMR to plate, tight! Okay... let's get'r done. I use a Vortex torque driver FYI. Vibratite and 12in-lb final setting.

When the plate was torqued to the slide, I had to really take my time getting the RMR to seat. That was kinda fun.. Ha!

All in place, NO HORIZONTAL LIGHT GAPS on either plane. Pefect. I do, however see ever so slight (and I mean slight) vertical light gaps at both fore & aft plate to slide, and aft plate to RMR. I'm not concerned, just an observation. I did see some "abrasion" on the front of my RMR when I had to work it in place to the mount plate. There ain't no gap there boys and girls.

All-in-all, perfect. Thank you Duffy!

Carry on,
Mack

The gap is sometimes unavoidable, we think Glock holds a 0.005 tolerance, we can't take up the slack because in so doing, we'd be making the plate not fit other slides, and would require the users to fit the plate into the pocket, which already happens.

The good news is we are confident OPF-G, RMR will work with the new RCR, we'll know for sure once we get one in our hands

We quietly doubled the quantity of RMR sight to plate screws, for both the RMR sight to plate screws SKU and all RMR plates packages.

With our plate design, the strength of the screw isn't crucial, as the plate itself holds the sight from moving, instead of relying on the screws to work as recoil lugs (a job they will fail at).  Many agencies treat RMR sight to plate screws as consumables, I imagine from the days of OEM plates when it was advisable to replace them after a battery change, so we always provide extra screws without being asked to for agency orders.

If you find 4 6-32x3/8 screws instead of 2, it's not an accident

I concur. Even thought it's not true Melonite / Nitride (think H&M Blacknitride+) man they do good work. Or the old European trade name "Tenifer," I still really like the nDLC finish on my new G48 MOS & G19.5 MOS.

Glock MOS plate to slide screws are not up to plate manufacturers, since the MOS pocket already has the holes tapped: M3 0.5mm x 6mm.  We source our screws from US shops, that is the only way we can ensure we get the quality we want.

These screws are COTS, like Glock, the screws we provide are T10.

Milled slides are fine if you're staying with that footprint for the next few years, the problem is that depending who does it, the quality isn't the same across the board.  A good shop like Battlewerx, Vulcan, Maple Leaf, Primary Machine, etc. will give you a tight fit, proper lugs (for sights that have lug holes), sight manufacturer spec footprints (for ACRO and MPS) and properly refinished.

But not all the shops can or will do that, it's the reason some agencies don't allow milled slides, lack of consistency.

It should, but since we don't have actual samples, we can't say for sure.  So far Trijicon has been very consistent with their data, when they say RMR footprint, I believe it.  I don't believe it when it comes from anyone else, save for Truglo, Trijicon owns Truglo
