To install, remove your front sight retaining pin, it is not necessary to remove the sight itself. Be sure to align the bushings retaining pin groove with the slides retaining pin groove. We suggest using a soft block of wood to drive the bushing until it seats on the bushing flange. NOTE: the bushing will only fit the 9mm “standard barrel” manual safety and decocker models: 75B, P-01, PCR, 75B Compact, 85C and 85B, and all modern CZ pistols with a .504″ OD barrel.
An alternate method is to freeze the bushing, which will shrink the OD, then install in the slide. Be sure and check the bushings ID fit on your barrel before installation to ensure a proper fit. Any questions contact CGW for tech support.
