Whenever I hear about loose screws I often wonder if they were assembled correctly. I've installed a very large number of these RMRs on the glock MOS and never had an issue and also fixed a few that were problems for others. I've personally shot tens of thousands of rounds and not had this issue.
Things I think I have learned. Have the correct screws (which means on an MOS the trijicon mos kit or aftermarket equivalent and on a milled gun what is the correct length and pitch). I have seen a few where the screw bottoms on the gun before it is properly fastened, normally because they try to use the screw included with the RMR and not the mos kit or those the person milling the slide required. Torque them properly (don't have a decent inch pound torque wrench you are kidding yourself with these small fasteners), use loctite (which to be used correctly means cleaned PRIMED fasteners with the product put in the hole not on the fastener, and no when you change the battery you can't just put them back in). RMR's vary quite a bit in actual size so make sure you have proper thread engagement (engineering rule is 1x diameter of the screw). sometimes you have to make some minor fitting to get there.
Doing those you will not have issues.
FWIW>

One question I have that hopefully someone can answer concerns the P320. It looks like on some of them that when you remove the plate to add the RDS the rear sight comes off with it. On Sig's website all they say is that it is compatible with the Romeo or the DPP. I know there are adapter plates available to use an RMR, but is the rear sight still there. I was looking at the P320 X Full. On the VTAC you can see that the rear sight is in a seperate dovetail but are they all like that.

On the newer stuff, the rear sight is attached to the plate. You can get the add-on rear sight for the DPP or there are a couple RMR plate options that either have a dovetail for a rear sight or have the rear sight milled into it. Bobro comes to mind.

That said I don’t think I have ever talked to anybody who disliked shooting with them once they got it down.

I took my new P320 with the romeo sight with me to my last 4 day defensive handgun class at Front Sight.... the 'secret' to acquiring the dot 'fast' is to use the iron sights and then refine with the dot... at least that worked for me.

DEHUGHES - Thank you for the video reference. Once I get my Canik TP9SFX set up, I will practice the prescribed technique.

Chasing the sights in works because with iron sights, you've got a constant reference to what you are doing right or wrong. You can fish the gun around some based on what you see to correct. With a red dot, you have a very narrow window to be able to see the dot, clean up the presentation, and be ready to fire.

The downside to the irons-then-dot method is that it means you either end up dot focused or having to then refocus on the target. The red dot is a target focused sight system - you look at the target and the dot is superimposed over it.

Everyone is different. But almost everyones eyes work the same. Find the irons, than find the dot is simply slow as it involves two distinct focus events. Don't learn, don't use it. it sucks.

I want to thanks those that responded. Will be calling my local blue label dealer today and looking for a G45 MOS (or maybe a G19, but use bigger mags). Will find best price on a RMR06 too. Looking around there are places where RMR is cheaper than the LEO discount that Trijicon offers ( 30%) through expertvoice website.

I'm carrying the sig 320 pro with romeo pro and a safariland 6365rds. The pro retains the rear sight without the plate and has taller sights to co-witness on the lower 3rd. Very happy with the setup. And it was a little over eight hundred bucks delivered.

What has the battery life been like on the Romeo?

Very good. Just have to remember to shut it off

Does it improve scores overall? Like—does it make someone who barely passes on a good day shoot significantly better?

I don’t see my agency going to those anytime soon, but I know we have recruits AND seasoned officers who fail every year.

I have limited experience with red dots on duty guns. But most of it is with teaching new cadets.

In my experience, red dots require solid grip/draw/presentation fundamentals, otherwise they spend way too much time hunting for the dot. That mirrors many of the complaints I've seen online from less skilled shooters who decide they want a handgun with a red dot, and then who get frustrated and complain that they can't find the dot when drawing and presenting the gun.

They seem to make moderately skilled shooters better/faster, but weak shooters can struggle even further with them.

I'm beginning to think that starting someone who's brand new to handguns on an iron sighted pistol first could be a better idea, and then transition to a red dot once they've mastered the shooting fundamentals.

When I first tried RMR, this was a problem, finding the dot, getting it on target. Handing the same gun to a guy with really good mechanicals proved I needed to work harder.

Red Dots can exacerbate bad habits, poor presentation, poor grip, bad trigger when moving from Irons that you've used for years.

With the Irons, as with any athletic endeavor, you learn to compensate for your deficiencies or remain average.

With the Dot if you don't correct them, you'll be frustrated, blame the dot, and go back, or, figure out what you are doing wrong and fix your grip, etc.

That's why top shooters improve quickly, they have the core fundamentals down, the dot then becomes easier to adjust to. Like Pro golfers, or the guy with the scratch handicap, they work at getting the swing mechanics correct, constantly.

I'd think if we started new shooters with the Dot over the irons it would produce better shooters, since they'd have to focus more on presentation and the mechanics of the shot.

This was my experience, found out all the stuff I've been doing wrong, quickly LOL

How does this work in a defensive or duty gun setting? I can't imagine carrying a gun for defensive purposes that requires you to turn on the sighting system before deploying it...so I imagine you'd have to turn it on and leave it on the entire time that you're working (or carrying). With that in nind, how long can you expect the battery to last? My typical work day (before the wuhan killed all my OT details) is about 16 hours...how many of those could I expect to get out of a single battery?

Answers to common RMR questions from Trijicon

https://www.trijicon.com/frequ...ns/category/rmr-faqs

What is the LED RMR battery life?

The RM01 and RM02 models are rated at two years typical use.

The NEW Adjustable LED RMR Type 2 has an automatic mode; how long before it resets?
The reset timer for the new RMR is approximately 16 hours. After 16 hours of no button pushes the optic will automatically adjust the brightness of the dot to match current lighting conditions. This feature will save battery life in dark storage but never deprive the shooter of an aiming solution.

Good to know about the RMR, and it sounds like a good system. What about the ROMEO?

Easy. I turn it off at the end of shift and turn it back on for next shift. Claims a 20,000 hour life.

I am surprised most of them don’t have a “shake to wake” mode if you will.

For duty use it’s moot. Like was said flip on at beginning of detail, flip off at end.

For home defense use I would think having said shake to wake would be very nice since I imagine most of our HD pistols sit in a safe/box/drawer type thing the vast majority of the time and having to turn on a dot or be faced with a dead battery seems counterproductive.

Dots on pistols intrigue me but I’m not ready to make the leap yet. I have only played with an Aimpoint on a Mark II but that is my only exposure.

What are they doing for backup irons? I see the plate uses the rear sight dovetail, and the RM44 doesn't appear to have integral sights built into it.

Also, how are you guys training to deal with water or fog on the lens? Do you aim over the top of the sight, or are there other techniques for this?

Good question.
Seems to me, backup irons are only valuable if the battery or circuitry fails, but you still have clear lenses.
If the lenses are opaqued by fog, rain, snow, mud, blood or salt spray, what good are co-witnessed irons?

Are any on-water/boat law enforcement agencies issuing RDS's?

Coast Guard, Wildlife, Sheriff Department River patrol, beach patrol, etc.?

That would suck as another item to fail. We don't worry about that on rifles since battery life is measured in years. And the RDS's are getting there. RMR easily seems ok with annual battery changes, so why have a nonsense feature.
