Strike Industries Prototype Glock Locking Block

A very promising prototype on display at SHOT Show was an aftermarket Locking Block for Glock pistols designed by Strike Industries. This drop-in part promises to substantially increase accuracy of off-the-shelf Glocks. The Strike block has to two additional features that help lock the barrel and slide more securely than the original. First of all it has a rail on each side that works alongside the front and rear frame rails. Secondly it has a ridge to the rear of the block that engages the chamber block that prevents the barrel/chamber from moving around.

These two changes seem simple enough, but when I handed an original Glock and a modified Glock on the SHOT Show floor, I was very impressed at how much better the barrel/side lockup felt. The proof, of course, will be how well it shoots at the range. As soon as we can get them to send us one, we will do a range test and report back to you.

    Could be interesting, Could be a problem disguised as a solution.

      Seems to me that Glock would have done this long ago if there wasn’t some very good reason not to. Sort of like all those Wolff springs that I have in a drawer somewhere, that made my Mosin too difficult to unlock or my SKS deliver light primer strikes. A problem disguised as a solution, indeed.

      • raz-0

        Glock has done enough back and forth on bits of the gun that I wouldn’t write anything off as being done or not being done having a good reason because glock.

        My first gut instinct is that this part needs to be fit. Mainly I suspect you need to take a file to that ridge until the particular lockup between a particular upper and lower is just right. Glock would never do that. However, it would be the simpler glock-ish version of a kart ez-fit barrel for a 1911.

        I’ve gotten to handle all metal mock glocks that are all aftermarket parts. They are pretty slick. Maybe not quite as durable, but accuracy, accuracy at speed, and handling characteristics were all improved by a tighter lockup and more mass.

  • Sledgecrowbar

    As long as it’s not double the price of a factory locking block, I’d buy it just to see if it makes a difference. My Lone Wolf G17L has two OE parts: the locking block and the magazine catch spring, because nobody else makes them.

    • thedonn007

      Speaking of that, what is the expected MSRP?

      • They have not figured out what it will see for. Its a prototype now and retail price depends on final manufacturing costs.

    • sam

      Yeah, I might want this: I mean, I’m the kind of person being spoken of here who could gain more by practicing. I admit I wouldn’t be using it to wring out the last scrap of competitive edge. But it seems like maybe an apples to apples improvement over stock, so if not too expensive why not. It would be nice if it feels, eh, tighter when firing.

  • liberty1776

    Interesting concept! Maybe this will be the start of Gen 5 mods?

  • Dante Zanone

    How much accuracy do you need within 50 yards? This is a product for people who are inaccurate and feel that buying something shiny will fix it. For MOST people, this will not help with accuracy. For MOST people the problem is with software not hardware.

    • Maximilian Johannes Benning

      good point. substantially increasing accuracy sounds great, but how much is that? Most shooters can put a good amount of bullets right where they want at 50 yards.

      That being said, one could buy this and go with the idea of “if my gun is the most accurate, reliable thing possible, then the only thing left to improve is myself, I can’t blame my gun for my failures”.

      • Dante Zanone

        I agree completely and see your logic. At some point, their $2000 Glock will show them they need to re-learn the fundamentals. Unless of course a ‘friend’ tells them they need a 1911. At which point they may need to sell a kidney after that customization. LOL

      • Yallan

        Head shots for sentry removal, urban sniping (Witin a 100 metres) with optics. The former is the reason behind the H&K USP more accurate design.

        • billyoblivion

          Yeah, because common use for handgun.

    • I have a Glock 17 SBR, and would appreciate more accuracy.

      • Dante Zanone

        How do you like your SBR? I’m exploring different SBR’s for a home defense gun.

        • You are not going to find anything lighter, IMHO, and it’s hard to go smaller. I’m running a KPOS G2 chassis, and love it.

          • Dante Zanone

            Thanks for the input. I’m now seriously looking at several kits with the G20. 🙂

    • iksnilol

      I can outshoot most common rifles (I learned to shoot on target guns, only flaw is the user there). Though I am not a good shot with a pistol, to be fair I have shot less than 200 rounds with pistols, I can keep about 70% of shots in the black at 25 meters. So for me I doubt it would help too much, but as you improve it is nice to not have the gun holding you back.

      + you can shoot pistols at impressive distances, you just need to know the techniques and practice (see 200 yard shots with 9mm pistols on Youtube and the like).

  • TCWriter

    Interesting. More than a few folks have suggested aftermarket barrels don’t really improve accuracy unless they’re the fitted variety, which always made me wonder if a more “accurate” locking block wouldn’t be a better investment than a more “accurate” barrel.

    Maybe we’ll find out.

    • Actually that was something the Strike guys said to me. I think the main buyer of the product would be someone who has previously purchased an aftermarket barrel.

      • TCWriter

        Probably true. Hard to imagine putting one on my G19 carry gun, but maybe my G34 (which has a Long Wolff barrel because I could only get lead bullets for a while).

  • Andrew Hobby

    I’m Extreeeeeemmely interested to hear about the New Kid on the Block, the Mock Glock Super Lock Striking Block.

  • Vitsaus

    Save trouble and money, buy a P226 instead of trying to make a glock shoot almost as good as one.

    • MrSatyre

      Or just learn how to shoot better. 😉

    • Nicks87

      My brand X is better than your brand X!

  • david

    The only reason to carry a Glock is because it works. It certainly not its looks nor its ergonomics. Leave it alone.

    • DonDrapersAcidTrip

      There are no rules about this.

  • Michael Y

    Will it kill reliability? I thought the loose tolerances were a reason they ran so well

  • A1l337sauce

    I for one am gonna buy this, the new Wilson barrell and a pws slide so I can double the price of the original and maybe see a marginal improvement in accuracy.

    • A1l337sauce

      Wait I forgot that I need that super sweet alg defense optics mount. Shot show just turned my glock into an erector set.

  • It would have been a nice touch if they had added fitting pads inside the block to control the horizontal play of the barrel’s lower lug.

  • Weeekley

    Are we looking at availability for all models and generations? I’d be interested in one for my Gen 2 21!

  • billyoblivion

    I had a buddy who could print cloverleafs with a stock Glock at 5 yards.

    At 15 you could cover his groups with a shot glass doing slow fire.

    Improve accuracy? Maybe.

    Substantially? Not for mortal humans.

  • Darryl Hadfield

    Was this to be a part of the glock complete upper that SI was talking about releasing?
