SHIELD CZ P10F/P09 +5/4 MAG EXT BLK

Description

The Shield Arms +5/+4 Magazine Extension is built for CZ P10F and P09 owners who want more rounds on tap without carrying a second magazine. It adds five rounds to a 9mm loadout or four rounds to a .40 S&W loadout, making it a practical choice for competition shooters running round-count stages or anyone who prefers a higher-capacity carry setup.

The extension is machined from aluminum, which keeps weight down while giving it the durability to handle the mechanical stress of repeated loading cycles and drops. Where this design sets itself apart from a standard base pad swap is the floor plate: Shield Arms engineered it so you can access the internal spring and follower directly without pulling the extension off the magazine body first. That matters during maintenance and malfunction drills, where fumbling with a disassembled magazine costs time.

Shield Arms backs this extension with a lifetime warranty and their Spring for Life guarantee, which covers the spring itself — the component most likely to fatigue over high round counts. The extension ships in black and is intended to be a drop-in fit on factory CZ P10F and P09 magazines with no gunsmithing required.
