Glock 19 mos Gen 5 or Glock 19 Gen 5?

[Glockoma86]

I am in the market for either a Glock 17/19/45 and don't really know which is the better way to go (mos or standard)? I like the adaptability to easily install optics on. I have been told that the plates however are poor quality. If I go with a standard series Glock that means I am going to have to get the slide milled. I am looking for feedback on it (personal experience, hypothetically & knowledge). If I go standard and have the slide milled it will then only be able to use and stick with one optics system and purchase another slide for anything different then. With the mos system I have the adaptability of usings multiple different optics with it. I'm also trying to figure out in the end of everything which is going to be the most economical purchase. Any insight is appreciated.

In the last few years, I’ve become a big Red Dot fan. I have a G19 MOS and shot around 3000 or so rounds with zero issues using all OEM Glock parts. I also have around 800 rounds through a G48 MOS, also with stock slide plates, also zero issues.

There are aftermarket MOS plates available but I’ve not bought any.

I have a factory MOS Glock 43X and an aftermarket Glock 17 slide with a cut and plate.

Nothing appears wrong with the OEM plate on the 43X, personally I would buy the Glock with the slide cut and covered until you decide to add a red dot.



As for the size you want, try to handle each of them to see where the 19-17-45 falls for you. As I’m sure you know, the grip is a tad longer on the 17 and 45 but the slide is shorter on the 19 and 45. This makes the conceal ability of the 19 a but easier as there is less butt to cover or worry about. One can get a full grip on the 17-45 with big hands so there are no issues with a poor grip.

While a few of us were shooting the consensus was the Glock 45 does have a bit more “whippy” recoil (a friends term as he shot mine Wednesday) than the 17 and the 19 did. I do think the balance is a bit different, but it may be due to the Gen 5 grip shape versus the Gen 4 (19) and Gen 3 (17) we were all comparing against each other.



All in all they’re pretty darn similar, but to me the 45 offers the best of most worlds for the 9mm Glock buyer.



Stay safe.

My issued duty weapon is a Glock 45 with a Trijicon RMR. I love it. If I could afford it, I'd set up my G22&23 the same.

By now it probably doesn't matter as the iron sight makers have probably caught up, but since everybody replaces the factory sights on Glock's, the non-MOS guns initially had more sight options than the MOS versions since the dovetail was farther back on the MOS gun and some of the older sight options would overhand the back of the slide.

If the plates are a worry, get a plate from these guys, they are fantastic.

That said, if I wanted a Glock and was certain I wanted a RDS, rather than a MOS I’d get a Shadow Systems 920. Better mounting system IMO and a bit more adaptable for new shooters while still being very Glocky.

Still, a Gen 5 19 is always a good choice, MOS or no. I have a pair, the MOS has a Holosun and the other doesnt

The mounting plates work just fine. I have a Glock 41 mos with 2500+ rounds fired with a Burris Fastfire III mounted on the correct included plate, it is solid. If you plan to mount a dot or reflex sight it cannot be beat.

Its definitely been beat by multiple manufactures.

Although the photo posted by @Riomouse911 with that keyed interface is a definite improvement on the sloppy crap they put on the larger guns.

Hmm ⁰

After doing more research around the web I now have some concerns about the long term durability of my Glock mount.

At the time I bought my 41 and mounted the Burris FF3 ( June 2019) there were concerns about mounting screw length.

I checked my screw depth against plate thickness for the plate to slide mount no problem.

I also checked the Burris mounting screws and the length of those was also fine.

Using glock oem plate 1, so far no issues. I am going to take my FF3 and the plate off however and check the screws anyway. I like the Idea of a tighter fitting slide mounting plate. The Glock plate on my 41 has a paper thickness gap between the plate and slide. Perhaps an aluminum shim could close the gap and prevent potential movement.

See the yellow sticky paper in the picture below:
So poor screw fit and a gap could certainly cause a failure after a couple thousand rounds +.
