Striker Control Device (SCD)

LTT Striker Control Device for Striker Fired 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 and Ruger RXM 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 or Timney Triggers, as these trigger options causes the striker to become fully tensioned, defeating the purpose/function of the SCD.

The SCD will NOT function in Glock clones or aftermarket Glock platforms. 

The roll pin that joins the two parts of the Slim Frame SCD is a wear item and we recommend replacing it every 8,000 rounds. Included in this package are two replacement roll pins for when maintenance is necessary. 

Update January 2025 - Gen 1-4 and Gen 5 SCD's will now ship with a solid roll pin.

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. 

Disclaimer: 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.
