New Optics-Ready Glock Models Soon To Be In Stores.

Kiesler Police Supply let slip the launch of Glock’s latest handguns, the MOS series. The new handguns are the same as standard Glocks, but with the addition of an optics-ready cut-out on the top of the handgun. Given the growth of the M&P line, one might easily assume these models are meant to compete directly with the C.O.R.E. optics-ready line.


I have confirmed the MOS series is already starting to make it into the distributors catalogs (though none show in-stock as of yet). Confirmed models are the G34 (9mm), G35 (.40), G40 (10mm), and G41 (.45). MSRP for all models is $699.

No mention of moving optics to the standard full-size offerings, but I would guess that once Glock has caught up with demand, they will be the next offering.

  • Zachary marrs

    Because when i think of a hunting pistol, i think of a 10mm longslide glock with a rmr


    • Anonymoose

      Can’t hunt here with a regular G20. It’s too short, but the 10mm is better for deer than the 41’s .45ACP.

      • JumpIf NotZero

        In my area no one uses them for hunting-actual, rather big game protection. A .357 mag is minimum, 44mag is fine, 12ga is best. For example, on moose.

        So while I’m not unused to the idea of having a 10mm glock on you while hunting, I’ve never given much thought to it being a primary hunting gun.

        Seems like an entirely valid use for an RMR.

        • FourString

          Yep, no one else has made an easily accessible, mass market 10mm pistol. I normally boo & hiss at Glock, but the one thing u can’t fault them for is stepping up to the 10mm plate when others won’t. If a bear caught me on the crapper, I’d much rather have a G20/40 strapped on me, thx very much ._.,

          (Ugh what I’d give for an H&K VP10. Pigs would fly before then though.)

          • I’d buy an H&K VP10 the second it became available. Of course – I said the same thing about the 10mm MP5 as well. I am still waiting for that too.

    • Tim U

      It’s the best of the options Glock produces without a substantial shift.

      I wouldn’t hunt with it either, but maybe someone wants it as a backup while hog hunting?

    • Nicks87

      Perfect for hog hunting.

    More interested to see if the thinner slide of the G41 makes it to the G21 and G20. They have already put the thinner slide from the G36 on the G30S, so I would imagine it would all work out right.

    • Nicholas Chen

      Why not just get a G41? That is what I did. My G41 is my preferred 45 glock now. My G21 is relegated to night stand duty. I am a little annoyed that my long threaded barrel for my G21 does not fit under the G41 slide.

      • tazman66gt

        Thinner slide with the same barrel length I mean, some people don’t want the extra length.

  • Scott Tuttle

    I know what I want for next christmas.

  • Joe

    Im just so excited to be able to say “its a Glock 40” and see the confused look on the ignorant folk at the gun shop when they see 10mm on the slide!

    • Mazryonh

      You’d still be right, because 10mm Auto is still .40 caliber wide, just longer than .40 S&W.

  • The pricing is good, but the sights aren’t high enough. Factory option for Trijicon suppressor-height sights would have been good.

  • Adam aka eddie d.

    To be honest I don’t understand the point of using standard height sights on a gun like this.
    In the US this can be easily remedied, since you buy whatever sights you just desire,
    but in most other countries you’re lucky if you’ll find even some decent night sights or fibre optic irons, let alone suppressor ready/red dot co-witnessing ones.

    I understand Glock is a huge company with an almost endless model list,
    so they can’t trick out every single type they have, but come on now.
    Is it really that hard to put some decent sights on these guns
    that are fit for the task?
    If S&W can do it with both the CORE and the Performance Center guns,
    Glock could do it too.

    • Nicholas Chen

      I agree. It seems rather lazy to not include taller sights for co-witnessing. However you could get the Leupold Deltapoint Pro with its integrated rear iron sight and just get a tall front sight.

      • noob

        would it make sense to have the optic set up for close range shooting and have a regular front sight and a tall rear sight for those crazy long range shots that we hear about? that way you don’t have to aim into the slide when elevating the front sight.

    • Stephen

      My understanding is that at least in the USA the sights are more of a placeholder to qualify for importation. Maybe they figured since the sights are likely to be replaced anyway, why bother? The alternative would be suppressor ready plastic sights…which I know I wouldn’t be happy with.

      • BattleshipGrey

        The question would be if they’re being made here in the US or actually being imported. If they’re not imported, then there’s not much excuse for low sights.

    • Nicks87

      Glock knows that everybody gets rid of the plastic factory sights anyway so they figure why bother. All my Glocks have aftermarket sights on them and I like it that way because the sights I use for CC are different from the sights I use for competition. Nothing wrong with Glock sights it’s just that nobody believes that they are as durable as metal ones.

  • jeff k

    damn .. more velocity in a 10mm … yup im getting one.

  • BattleshipGrey

    Hmm, so they’ve taken the hassle out of sending your pistol to the shop to be milled, but you still have to take it somewhere to replace the sights? Or do you get to choose the sights when you order?

    I swore off of Kiesler’s a while ago so I hope this is just a sample of one of the coming vendors. They’ve got the trifecta of a terrible website, vague (sometimes non-existant) pricing and spotty customer service.

  • BattleshipGrey

    Either the vendors DIDN’T let it slip, OR we slide by another year without the introduction of the Glock carbine.

    • JumpIf NotZero

      Seriously, not until the old man is dead.

      • BattleshipGrey

        I bet if he could figure out what designation to give it we’d have it by now. I’ve been wondering what model number they’d start with on the carbines, since they’ve already got the principle worked out for their pistol market. I’m not a perfectionist by any means, but when it comes to designations, I like to have reason and uniformity behind it.

  • Nicholas Chen

    I wonder why the G41 doesnt come with the extended slide stop/release like the G34/35?

    • All the 20, 21, 40 and 41 pistols should come with them. The slide overhangs the slide stop a bit more than on the small frame pistols.

  • Ratcraft

    I see a G40 in my future. Then what? Where do I go from there? Kind of a buzz kill. Hey…… I have 2 hands….. yes!

  • Fred Domini

    The G41 MOS looks promising for NRA Bullseye, but the typical Glock trigger is anything but “match ready”.

  • FourString

    I see what you did there. G22 in .40 S&W; G40 in .22LR–hahh

  • Tassiebush

    So the optics just sit on the slide and don’t get shaken to oblivion each time it is fired!? Wow!

  • Nicks87

    S&W and now Glock are the only ones I see with a slide cut out and maybe a few custom 1911s but those are not production guns.

  • Nicks87

    I carried a G17 with factory sights on duty for a few years and never had any problems with them. I just prefer a 2 dot system.

  • Nicks87

    Ok so add FNH to the list and you still only have three. I’m not talking about having a shop cut a channel in your slide, I’m talking about production guns that you can buy off the shelf. I think some people just take every chance they can get to sh*t on glock.

  • Harold

    Look forward to see if these are as nice as the ones from Gabe Suarez and One Source Tactical.

  • Carlos Velazquez

    I wonder if this will come on the fabled Glock carbine that is rumored to be released one of these days eventually.
