GLOCK 34 + Optic

jedi · Jul 1, 2024

If one has a Glock 34 Gen 4 "basic" model and wants to add this optic below

SIG SAUER Romeo1 Pro 1x30mm Red Dot Sight, 6 MOA Dot Reticle, Aircraft Grade Aluminum, Black, SOR1P101 — Color: Black, Fabric/Material: Aircraft Grade Aluminum, Magnification: 1 x, Objective Lens Diameter: 30 mm — SOR1P101

I take it the slide needs to be changed out for a slide that has the holes to accept the screws for the optic right?

Could one just get the Glock 34 Gen 4 MOS slide and will that work? Or is there another slide?

I'm not a Glock owner, but I'm willing to bet that's all it would take. That's the way it worked to upgrade my Taurus G3c standard to optic ready, anyhow.

A gunsmith, like AllenM, could mill your G34 slide to accommodate the red dot sight. Some argue this is a better bet than to go with the Glock MOS system? A slide milled to your sight specs rides the closest to the bore. Whereas the MOS system slide will require an adaptor plate that adds a slight bit of height to the sight picture, requiring suppressor height irons for your backup.

Either way, its gonna be costly to convert your G34 to optic ready. On top of the cost of the optic, you will have a prima donna gun with more money invested than recoverable.

My :twocents:

...

Sell or trade the G34. If you are dedicating the gun to red dot sighting anyway, no need for the longer iron sight radius of the G34 or even G17. Buy a G45 MOS or G19 MOS as the red dot sight doesn't benefit from a long sight radius. Icing on the cake is that the G19 slide legnth is THE MOST popular slide legnth on the planet. Accessories and gear options are at the top of all lists for this model.

Contrary to the folks who only subscribe to milling the slide, for a perfect red dot mesh, I think differerently. I want a pistol with options, be it changing red dot systems or reselling the pistol for the next one. Cut on your Glock and you drastically reduce your resale value. Even with the slide work done by the best of gunsmiths, there is no bringing it back to factory spec.

The Holosun SCS is the only red dot sight that directly mounts into the Glock MOS system. This sight/gun combination allows stock height sights to co-witness. It's what I have carried since the SCS has come out.

Easiest answer these days is buy a gen 5 that has the MOS cut, and a holoson SCS model that's made specific to that fit. Done.

I agree!

That said, the SCS has a small window. You will need a steady regiment of dry fire and or range time to stay on your game of drawing to the dot on target every time.

Slide and slide completion kit. Move your barrel and recoil spring over. Leave your OEM slide intact.

Then will in turn mill and mount the optic and ship back.

They will even switch out the iron sights if need be to ensure the optic is not in the way.

I’m late but I’ll make a suggestion from watching a lot of Red Dot Glocks in Spaulding’s Red Dot Class and Rangemaster basic and advanced instructor course.

DO NOT have a non MOS Slide milled with Glocks the issue is you will set up your gun for a malfunction in the ejected case WILL AT SOME Point bounce off the optic and catch in the ejection port and hold it open. Sort of like a stovepipe but flush and often backwards.

Spaulding covered that in his classroom portion and sure as s&$t it happened several times that day with the non MOS milled Glocks I also saw it several times and when asked it was always the Glocks that had aftermarket milling. The issue is about 1/8” rear sights on Glock MOS versions are 1/8” back Glock like them ir not sort of know what they are doing and I am sure ran into the same issue why they moved the sight slot back slightly.

For those that think they are the exception….OK you will be OR haven’t went through a 500 round a day class yet!

Just my real experience going to to relevant classes that was addressed by a very knowledgeable and relevant instructor!

Good luck!

So any idea where to buy a GLOCK 34 gen 4 MOS slide then?

Can't seem to find that anywhere

Yeah it seems to be a almost non-existed item. Even tried ebay and nothing.

I may be better off just buying another GLOCK in the MOS flavor but then I'll have no need for this current one.

Sometimes the headache saved by just buying a Gen 5 is worth the $$. Put the gen 4 up for your rainy day gun or like it’s gonna quit working .

Good luck

Could just sell your current G34 and buy a MOS version. I have a Gen5 G34 MOS and shoots well for me , had a Vortex Venom 6MOA at first and recently switched to a Holosun 3MOA.

I am glad to see some commentary on the rear sight slot difference on Glock MOS versions! Couldn't help but notice my Ameriglo rear sight protrudes from the rear of the slide by that 1/8" on my G19 MOS. Certainly can see how that 1/8 setback for the optic makes a huge difference in clearance for ejected cases. Especially with some of the really tall, large window optics.

I was contemplating picking up a backup G45 earlier this year that had been milled for the optic. Happy I didn't end up doing it. Certainly don't need a problem waiting to happen.

:yesway:

Gingerbeardman · Jul 5, 2024

I took my red dot off awhile ago but IIRC I just removed the rear sight and installed a mounting plate in the dovetail. I only used it for shooting competitions but never had any issues with it.

If you aren't on a time schedule and can shop, the price difference between selling your Gen4 G34 in the classy's and buying a slightly seasoned MOS version Glock from the same INGO classifieds is not gonna be that much. Certainly not nearly as much as milling or buying another slide.

That also gives you options not to be locked into the G34 size pistol.

:twocents:

jedi · Jul 5, 2024

I am not in any rush.

:facepalm:

completely forgot about the INGO classified section.

It's not about the cost per say. It's more about the hassle. The G34 Gen4 I have is my current EDC.

Moving to a red dot means having to buy a new holster as well. Plus don't think I would sell this G34 as it could be a backup/range gun for the new shooters I take to the range.

or just double carry one on each side.of the hip.

www.indianagunowners.com

I think this is priced a bit high, but might be worth a watch to see if that changes? Comes with a couple holsters, one is optic cut, the other might be user adaptable? If the gent's G45 MOS package doesn't sell for a while, then maybe the seller might be willing to separate the gun from the holsters? (G19 sized holsters are the most popular size on the planet, for selling and buying. )

Just sayin'...

I think many forgot about the new dot system made for non cut firearms. It is magnetic and fits anything. Thought the videos were posted on ingo but can't find them.
