Glock MOS

I have a Glock 34 Gen 4 MOS. I've mounted a Leopold Deltapoint Pro with the 7.5 MOA triangle. I use this gun for the Carry Optics division in USPSA.

My gun came with one of the worst Glock triggers I've encountered, which is saying something. I've replaced the Glock trigger with one from DK Customs. It is a 2 lb trigger for competition only. I've also changed out the guide rod to a stainless guide rod with a single spring -- I'm running about 130 PF using 158 gr loads, and the stock spring was too stiff. This gun is solely a game gun for me.

I'm over 55, so I'm having a harder and harder time seeing iron sights. I can see the red dot.

That said, on very close targets, I'm a bit slower with the red dot. Sometimes I can end up searching for the dot if my draw isn't clean. At longer distances, I am much, much faster and more accurate with the dot than with irons.

The Deltapoint Pro is a large red dot, with a large field of view. That makes it great for competition, but I think it would be a challenge to carry.
 
Hmmmmmm I am leaning towads an RMR and Vogel Comp Trigger. I do have to say I really like it more than I thought I would.

Are you still runnng iron sights on yours? Seems Trijicon surprssor sights are about all thats out there without going custom.

I'd love any mos type gun. Totally jonesing for an MOS anything. I'd love a g35 with a 357 sig conversion barrel. Probably for the same reason. Eyes are getting slower. And it helps with the red dots.
 
I picked up a Glock 17 MOS to have as a range toy and like it. Since I was going to put an optic on it I didn't need the extra sight radius of a G34. After lots of research I decided the Burris FastFire III was the optic for me. I wanted the lifetime no BS warranty because it is a range toy that I let lots of other people shoot and play with, and the price was very reasonable compared to the others. So far everyone that shoots it likes it. Currently I'm shooting primarily iron sights on a G34 but I can see myself switching to the MOS in a few years when my eyesight gets worse.

I picked up a G34 MOS a few months back and put a Vortex Viper on it. I noticed that I'm a little slower on my shots with the G34 vs G19, but my shot placement is a lot tighter.

No iron sites on mine. It is a game gun.
 
I can respect your resoning, after all they are your specific needs. Strictly FYI based on all my research if you want cowitness iron sights the RMR is the only one that will allow you to do so. Now thats with adding surpressor sights and the seperate RMR Mount Sealing Plate that come with shorter screws which is needed and not supplied by Glock and is sold seperatly by Trijicon for the Glock MOS if mounting an RMR.

I don't think cowitnessing is very important on a pistol.

I've shot guns with dots that had suppressor sights and not. There is something about the sights that 'guides' me to find the dot faster.
That being said, I wish the MOS was cut so low that the base of the red dot was buerried. Wouldn't need suppressor sights and the sight alignment would be more natural. Glock could have done this with some changes to the MOS design.

Yeah, if you want to cowitness iron sights that may change your red dot choice. I have no interest in doing that. In fact, I was thinking of removing the iron (plastic) sights altogether so as not to distract the shooter. Remember, mine is a range toy that a lot of beginners shoot.

I'm in the process of selecting a sight for my 41. I like the idea of minimal obstruction of view, but at the same time don't want a sight that which is likely to become useless it if takes a bump. And I'm still not set on dot size. The only RDS I've used is 3 MOA, which works fine on a rifle for precision shots. But this would be for the range (up to 50 yards), and house.

I see that Loopy RDS has an add-on rear sight available; Leupold DeltaPoint Pro Rear Iron Sight. Not sure how that would work out.

The Leupold is expensive and only comes with a 2 year warranty on the electronics. I chose the Burris FF3 for three main reasons:
1. Lifetime no BS warranty.
2. Battery can be replaced without having to remove the sight. Then you have to sight it in again. Too much of a pain.
3. Price. I wasn't sure I would like a dot on a pistol and didn't want to spend a lot.

I got the 8 MOA dot size and couldn't be happier with my choice.

Leupold Deltapoint Pro does not have to be removed to replace the battery.

True, it was the 2 year warranty on the electronics that turned me off on that one.

I picked up a deal on an RMR, and I've been thinking about dots on pistols for a while. Unfortunately, no one near by has one that isn't on a 22LR. So, I found this mount:

Not as low as a machined slide would allow, but I'm hoping it'll be enough to see if I like it. If I do I can get a slide milled out for one, if I don't like it I won't be looking at a permanently modified slide.
 
I know its sport around here to bash glock sights. But I usually just paint the rear Glock sight black (if its adjustable) or flip it around, if its fixed and go with it.

So I was pleased to see on a very recent MOS Glock 34 that they were now shipping them with adjustable sights. When they first launched they had fixed sights because standard Glock adjustables wouldn't clear the cut in the slide. The new sights hang waaaay back from the sight dovetail.

Factory Glock sights don't have enough light between the front sight and rear sight for my eyes. For me, the front sight is too wide and the rear notch too narrow.

I agree. I usually put a fiber optic on the front, and spend 5 minuts with a square needle file widening the rear notch. After that, the rear works great. I also flip fixed sights around so the white outline faces forward.

I prefer to just install a 10-8, Dawson, or Heinie rear sight. Not as cheap, but I prefer the sight picture.
 
Guys, we're talking about an MOS pistol with a mini red dot sight. Who the heck needs iron sights too? I'd prefer to get a blank that I can slide in and will take up the rear notch to make it look like a flush fit with the slide.
 
There are never too many sights! On my glock g40 MOS I have a red dot vortex venom sight, days sights, night sights, websights, etc on it!

UPDATE (long over due):
So for me and my intended uses(s) which are general range training/prioficentcy/fun and OWB carry with a BH Serpa Holster. I've nailed it down after trying a few different red dots, Dawson and Trijicon Suppressor Sights. The winners are RMR07, Vogel Comp Trigger at 3.5lbs and the Trijicon Suppressor Sights. For me I want to be able to cowitness irons and optic. 1. I acquire the dot much much faster to put it on target. 2. If the dot fails in a situation I am not SOL.
 
I have a 34 mos and my current setup on it is warren tactical fiber front,blacked rear. I run a jpoint low optic mount set up for the jpoint/Shields rmr optic. The optic is a 4 Moa dot. Very precise and is the lowest sitting optic on the market when you combine it with the j point mount. It allows a lower third co witness with normal height sights. I'm glad I found this combo as with the mos platform most optics sit pretty high once you mount everything up. This causes even suppressor height sights to only be a lower third co witness if your lucky. Dawson makes a set of high sights for mos platforms but they are super tall and look almost funny on the gun. Pm me if you would like to know more info and or even shoot mine to see if that set up would work for you. I like the shields so much I'm considering swapping out some of my trijicon optics to possible get more of them
 
Hmmmmmmmmmmmmmmmm So the Jpoint4 with the #4 MOS plate and a pair of M4x0.7 or M5x0.7 screws and thats it. That will allow "normal sights"?

I've been experimenting with Trijicon RMR's on G19's and G17's for 3-4 years now. My short-range (under 15 yards) shots continue to be slower with the RMR compared to iron sights, as I struggle to pick up the dot. I think the problems include 1) the RMR screen is small and I'm wiggling the muzzle to find the red dot; 2) the suppressor height sights are not what I use normally for iron sights, so I don't pick up the front sight quickly; 3) the RMR screen is tinted a somewhat dark blue, so it is hard to quickly see the front sight and then subsequently the red dot. At longer distances, I'm only slightly more accurate with the red dot than I am with iron sights. The other hassle is you need to remove the Trijicon RMR from the slide to replace the battery (on the bottom of the unit), add your blue loctite, and then re-zero each time, which is a pain. So, after 4 years, I'm still not sold.

I just picked up a G19 MOS and installed the Shield RMS that Bentone mentioned above. With the Shield plate, you don't need suppressor height sights, so I left my standard Trijicon iron night sights on. I pick up the front sight and the red dot very easily, though I've yet to use a timer to see if my time to first shot is equal to my time with iron sights. The screen is very clear, so I'm not dealing with the blue tint, which I found irritating. The battery changes from the side, so no need to remove the optic, which is another plus.

I'm still not to the point where I'd daily carry a red dot optic on my pistol (I don't want to be waving my muzzle around searching around for the dot in a defensive situation), but this Shield RMS might be the solution.
