NOTE: Degrease the loaded chamber indicator plate female threads and the male threads on this screw. We use a tiny drop of blue Loctite to ensure the screw will not back out.
CAUTION: Never run your CZ 97 without the loaded chamber indicator in place or damage to your CZ can occur. The plate is the barrels vertical limit position and is absolutely crucial for safe reliable operation of the pistol.
If you need the plate, see part number 97002, the spring is 97003, and the pin is 97001.
