Pre-positioned bosses, slots and holes remove pressure from critical function surfaces while pins are driven in and out. Thumb Safety and Magazine disconnect drop into holes and slots to prevent damage no matter what position they are in. High Density Polymer construction prevents marring of the frame while driving pins in and out. Retaining slots on each side of the block hold the striker making removal and installation of the striker spring a breeze. One side is for the 45 striker and the other is for the 9/40/357 striker. Moveable bosses are easily adjustable to position frames quickly and easily.
