The Apex Tactical Enhanced Ambidextrous Slide Release for the CZ P-10 fits the P-10 C (compact), P-10 F (full size) and P-10 S (subcompact) in 9mm and .40 S&W. It does not fit the P-10 in .45 ACP. The part is CNC-machined from steel and finished in Black Melonite, which resists corrosion and holds up to holster wear. Apex widened the paddles on both sides, so your thumb finds the release faster on a reload, whether you shoot right- or left-handed. Features: Fits CZ P-10 C, P-10 F and P-10 S in 9mm and .40 S&W Excludes the P-10 in .45 ACP CNC-machined steel construction Black Melonite finish for corrosion resistance Enhanced ambidextrous paddles Wider, more ergonomic thumb contact surface Why upgrade the slide release: a standard slide release is small and sits close to the frame, which makes it easy to miss under stress or with gloves. A wider paddle gives you a positive contact point for sending the slide home or locking it back to clear a malfunction. Before you install: confirm your P-10 model and caliber. After installation, unload the pistol and function-check it: lock the slide open on an empty magazine, release it with the new paddle from both sides, and make sure the slide does not lock back on its own while you shoot. Ask a qualified gunsmith if you are unsure about detail-stripping the frame.
