This plate allows you to make adjustments without having to take the back plate off your gun every time. The plate is sectioned by 1/3 in height to permit viewing of the sear and firing pin engagement. This plate is slightly thicker in width than the OEM plate. This plate is made thicker in width because this thickness moves the firing pin leg slightly forward. Moving the firing pin leg effects where the trigger releases the firing pin. Moving it slightly forward gives you more adjustment of the Trigger Control Tab (TCT) once your thinner Glock black plate is reinstalled.More Adjustments may be required This plate is a virtual must for an easier error free installation of the EVO ELITE, ROCKET & TACTICAL. This is a Test Plate. This is a must have tool if your going to work on your Glock! Does Not Fit Glock models G42 & G43 Visit Our Store For More Ghost Products! Pictures are courtesy of Ghost inc.
