LTT Striker Control Device for Glock Handguns

Formerly developed by Tau Development Group, Langdon Tactical Technology, Inc. is now manufacturing the Striker Control Device. 

What is the Striker Control Device? 

The Striker Control Device (SCD) is a cover plate for your Glock pistol that blocks the rearward motion of the striker when thumb pressure is applied to the back of the slide – similar to a hammer on a DA/SA hammer fired pistol. It was originally developed by Tom Jones and Todd Louis Green from the inspiration of double action hammer fired pistols, where shooters are taught to keep their thumb on the hammer when holstering. Keeping your thumb on the back of the hammer gives you positive feedback should something be caught in the trigger guard to prevent the gun from firing.  The SCD does just that for the Glock striker fired pistols. 

  • The SCD blocks movement of the trigger bar and prevents the trigger from moving.
  • The SCD does not lock or otherwise interfere with the normal operation of the pistol unless physical force is being purposely applied by the user. When using any normal firing grip (IE: hand is not on the back of the slide), the SCD is not engaged, acting as a traditional back plate. 
  • Installation of the SCD requires you to remove the existing backplate and install the SCD. 

The LTT SCD works with all of the Gen 5 Glock pistols (yes, this includes the Glock 20). Check out the installation video here. 

The Slim Frame & Full Size SCD DO NOT fit or function with the Glock 42. 

HAVE YOU SEEN THE GRIP ANCHOR? Add this to your cart for the Glock 19, too! 

Please Note: The SCD will NOT function correctly with the Glock® Performance Trigger, as this OEM trigger option causes the striker to become fully tensioned, defeating the purpose/function of the SCD.

Delivery Times: 

If you are able to purchase, they are in stock. If not, please add your name to the wishlist to be notified when that size is in stock. 

The SCD does NOT replace safe gun handling. It creates an additional layer of safety and control by providing feedback to a shooter should something get inside the trigger guard that should not be. The SCD is designed to work with stock Glock triggers and aftermarket trigger components that do NOT alter pre-travel. This part has been developed by LANGDON TACTICAL TECHNOLOGY, INC. “GLOCK” is a federally registered trademark of GLOCK, Inc. and is one of many trademarks owned by GLOCK, Inc. or GLOCK Ges.m.b.H.

    Love the added safety

    Posted by Daniel on Oct 17th 2023

    Was tentative to order this bc I have an Apex trigger in my 43x. I reached out to Langdon Tactical and asked if the Glock SCD would still work. They quickly confirmed the product would work. Once it arrived I installed it and sure enough, it works with the Apex trigger. Super happy with this purchase and the added safety it brings to my EDC gun.

    Striker Control Device

    Posted by Greg Brown on Apr 25th 2023

    I really like the tactile feedback the Striker Control Device provides as I reholster. I only gave the device 4 of 5 stars because the device failed after about 15,000 rounds. The hinge pin that the device swivels on fell apart. However, I like it enough to order a replacement as I'd much rather have it than the OEM part.

    Extremely fast order handling and shipping. I installed the device on my PSA Dagger (G19 clone) and it works perfectly. Thanks Langdon!

    Langdon Tactical's SCD is well made and actually works exactly as it should. Beware the ebay copies - cheap, but made out of plastic. Spend the money to get it right.

    I carry appendix, so I like the added safety and tactile advantage given by the Striker Control Device. Thank you, Langdon Tactical, for taking over the production of the SCDs.

    Great Gadget

    Ran it on my G19 for a two-day concealed carry class. No problems. Highly recommend as an easy to use added level of safety.

    We’re Back, Baby

    Snagged a Langdon SCD for the 34 to compliment my original on the 19. Love that these in production again. After using one it’s pretty much mandatory for any Glock I own and carry.

    LTT For the Win!

    Posted by Mike Delcampo on Apr 27th 2022

    I stalked TAU everyday just waiting. Then I saw Ernest on YouTube. Yep stalked them daily until I finally got mine. Well worth the cost of peace of mind when holstering. Great concept, great products. Thank you team for continuing the TAU legacy.
