So, just got this yesterday. Just to double check, I just need another OPF-G, same ice as my 19s, it just won’t hand over the sides of the slide?

Also, I can use the GL-429s with the RMR on the 20 as well?

OPF-G, RMR will be flush with the slide, whereas on 1" slides like 17, 19, 45, and 47, there's a slight overhang.

The front 2 corners don't match with the wider slide as the plate is contoured for 1" wide slides, but it's cosmetics.

Yes you can use GL-429 with RMR.

Roger,
I know it's only cosmetic, but if you ever change the milling dimensions to match the contours of the larger guns, you'll sell a lot of plates.  You are THE go to plate system.

The existing design works on both 1" and 1.12" slides.  While the wider 1.12" plate, if we made one, would only be suitable on Glocks with the wide slide, we can do it but it'll add another layer of logistics and potential for mistakes.  It'll work on 1" slides, but it'd be far less pleasant than the gap the current plate creates on a 1.12" wide slide.

When folks get the plates second hand, it may not be disclosed it's for one or the other, then we'll be on the hook to exchange it.

Since functionally there is no difference, we're reluctant to make this change with unintended consequences that come with it.

So I’m new to the MOS game. While tempted to have the slide milled, I decided to sell my 19 to a friend and just bought a 19/mos.  My question is this.  I plan to buy an aimpoint P2 for it, but wondering why I can’t use the provided glock plate? I’m ok with buying once and crying once… just don’t know what I’m missing.

(For reference this will be paired with a rifle with a scalarworks t2 combo- so I want a quality setup.

My G47 didn't come with the 4 plates my G45 did, it came with 1 plate and it looks like an RMR plate.

ACRO P1/P2 and MPS in our experience are great optics, they're not forgiving of plates made with poor tolerances, or dimensions that don't follow ACRO TDP.  Tangodown/FCD plates are well regarded, but I suggest you contact Aimpoint and Steiner and ask them what they recommend

We're developing more ACRO plates.  Next up: Staccato ACRO plates, maybe FN509/510/545 ACRO plates.

As a buy once cry once guy myself.  Buy the FCD plate and know you are doing the right thing.  I work LE and our department does not allow RDS yet for duty guns.  WE can choose from 17, 19, 19X, 45 and 34.  My partner is the only one in our department that carries a 34 and he has a DPP on his off duty/competition gun.  He was shooting a match a few months ago and using an MOS plate.  Middle of the match the screws sheered off due to the MOS plates known issues and his DPP went flying.  Then he had to go get the broken screw drilled out with a drill press.  

Get the FCD

Do you swap second-hand OPF-PDP plates for new OPF-G RMR plates because the seller misrepresented what he had?

If all I cared about was functionality and didn't give a squat about clean lines, I'd just use the Glock plates.  They work well enough.

Just got the FCD plate.  Seems solid.  One screw was definitely harder to turn in than the other, I even backed all the way out and tried again.  

Will shoot it (gen 5 G17) this weekend.  I think it'll work fine.

PDP and Glock RMR plates are not interchangeable, we warranty our plates for the life of the product.  We do exchange them when customers order the wrong plates.

Duffy/Roger, I know your busy and probably have a ton of other projects your working on and a bunch more in the works… but there desperately needs to be a mos to holosun eps/eps carry plate made with the quality that FCD puts out…the few that are out there that I’ve tried, are very lacking when compared to the FCD mos/rmr plate I have.

I’m very tempted to get one of your DDP plates and grind the back posts off…but would have to dremel up such a nice plate…

And yeah, yeah hate on holosun, but the eps is a killer optic, and I still run rmrs with FCD plates on my main squeezes

I totally respect that Duffy, and while I just asked for a plate to a non U.S. sight, I stand behind you in that statement as well.  I’m sure I’m not alone when I say I appreciate the work you have done already, with the plates/accessories you offer.  FCD is the best mos/rmr plate, period!

Thank you guys for understanding.  

We have our reasons, some of which I won't discuss publicly, the one I can state is that we're an American company, we choose to support other US companies, and companies from allied countries. We're a tiny company with little to no influence to wield.  I don't expect others to understand or follow.

I just bought a plate from FCD, because of this thread.  Put it on my G45 MOS yesterday.  Fit perfect with only a small amount of pressure to get the RMR in the plate yet fits snug.  I’m still waiting on the Glock Performance Trigger from GlockStore before I go re-zero but I’m wondering if the trigger is going to be vaporware.  Went ahead and installed the Glock extended slide stop and magazine release.

Tango Down sells a really good tool for getting under the mag release spring to release it and clip it back in the mag release without scratching up the mag well.  GMRT-01 is the part number and Brownelled sells it.Attachment Attached File

Posted it on our site under FAQ.

An often asked question is if our OPF-G (Optics Platform FCD, Glock) plates, designed and made for 9mm 1" slides work on wider slides, such as G20, G21 and G22.  The short answer is OPF-G, RMR, OPF-G, RMRcc, OPF-G, DPP, OPF-G, EFLX, and OPF-G, ACRO all work with the wider G20 and G21 (1.12") and G22 (1.08") wide slides.

All but OPF-G, RMR will leave a slight gap on both sides of the plate.  This gap is cosmetic only, it's either we have a "step" between the plate and slide, or a step between the sight and plate if we made the plates wider.  A wider plate to accommodate the wider slide will not do a thing better.

OPF-G, RMR is wider, as RMR and SRO are wider than RMRcc, DPP, EFLX and ACRO.  OPF-G, RMR does not leave a gap between the plate and slide, but the front two corners contour was made for 1" 9mm slides, the contour doesn't match the corners of wider slides.

We have no plans to make wider plates for these models with slightly wider slides, as it'd only be cosmetic.  Wider plates for specific models can confuse customers, and will complicate logistics for us and our dealers.

Below pictures illustrate how OPF-G, RMR,, OPF-G, DPP, OPF-G, EFLX, and OPF-G, ACRO look on a G20 (1.12" wide) slide.

I bought a G17 Gen 5 MOS, tried to use one of the included plates and as I tightened down the screws one side of the plate would lift up off the slide. Wonkiest shit I ever saw, would have thought it was a pot metal airsoft plate but it came with the gun, with Glock markings all over the package. Promptly threw that crap in the trash, did some googling and then ordered a FCD plate and never looked back.

You were using incorrect and too long of mounting screws for the red dot.  They went all the way through the plate and were pushing against the slide which was causing the bend.  Common issue since people think the screws Glock includes with plates are correct for every dot, but they aren’t.

We include a packet of Vibratite VC3 with OPF-G, RMR, it's what we'd like to use.

Re: screws 6-32x3/8 is the RMR sight to plate screws spec.  Ours are T10, McMaster has T15 (same thread pitch and length, but with T15 drive instead of T10) McMaster

For H users, do not use our sight to plate screws, they'd be too long for H sights.  H sights use a curious combination of metric pattern countersink and inch pattern threads.  RMR and SRO countersink angle is 82 degrees, H sights have theirs at 90 degrees.

Negative, just screwing the plate onto the slide made one end of the plate raise up off the slide.

Just ordered another plate from FCD as I’m trying a Steiner this time.

I’ve seen conflicting opinions as to whether the Steiner MPS needs suppressor height sights. Any idea one way of the other?

With a Glock, sight sets with 0.315" front will work with MPS.

I created this from a G43 frame and G43X MOS slide, with OPF-G43X, RMRcc and BIS, G43X (backup sights), the intention is to bring it to TTPOA and have some fun showing it to the SWAT guys, I had no idea it would feel and handle so well

You know what's funny, all over the internets people get all self-righteous about how they hate the MOS because the "red dot is too high" and must only have specially milled slides, because apparently when you are holding a pistol at arm's length that few extra millimeters throw everything off.  But when it comes to the 43x or 48, sitting a slightly smaller RMR up on top of the slide (via a plate, mind you) where it seemingly doubles the height of the pistol is totally A-OK.  I have no idea why this type of mindset exists.

Link Posted: 4/1/2023 5:17:01 PM EDT
[#37]
Some prefer their MRDS mounted as low as possible, some don't care.  I'm in the second group.  A slightly taller installed height in exchange for versatility is more than a favorite tradeoff, to me it's a no brainer.  But folks have choices, as long as they know choices can have unintended consequences down the road.

MOS offers modularity a milled slide doesn't, when other US manufacturers introduce their enclosed emitter sights, this modularity allows folks to switch to these optics as long as there are competent plates made for them.  We already make all of them
