CZ thumb rests and extended slide stops for consistent hand placement and faster slide manipulation. Thumb rests index your support hand without interfering with controls, improving split times on Production guns. Extended slide stops let you release the slide without shifting grip after a reload — a small upgrade with real match impact in USPSA and IDPA. Compatible with CZ 75, SP-01, and Shadow 2 platforms. Fast same-day shipping on most orders at Shooters Connection.
