Strike Industries Slide Adapter Plate for Glock Gen3/4

The Strike Industries Slide Adapter Plate for Glock Gen3/4 allows you to use a GEN3 slide (with or without Mass Driver Comp) on a GEN4 frame. Naturally a Glock factory or aftermarket GEN3 slide will fit and function on a GEN4 frame, but there are a few issues to address. First is the ugly gap and the second is the flex in the frame because of the large hole. Install the Strike Industries G-SAP in seconds and prevent any movement of the GEN3 recoil rod and spring from possibly damaging your Glock GEN4 receiver.
