Langdon Tactical Technology Striker Control Device / SCD, for full-size Gen 5 GLOCK pistols.
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. LTT has SCD’s in production for slim frame guns (43, 43X and the 48), and we will stock them as soon as they are available. We do not have any ETA on availability.

Works great. Just as it was designed, it allows me re-holster and know if something has entered the trigger guard and is about to fire the weapon. All while not interfering with the normal operation of the weapon. I got one to try out and now I’m looking buy several more for my other Glocks.

The LTT SCD is as good as my original Tau Dev SCDs.
