Kci Usa Inc KCI-MZ049 10/15rd 40 S&W Black Hardened Steel/Polymer KCIMZ049

KCI USA 10/15-Round Magazine — .40 S&W, Black, Hardened Steel/Polymer (KCI-MZ049 | KCIMZ049 | UPC 851586008511) Full-size .40 performance with capacity for restricted states. The KCI USA 10/15rd Magazine uses a standard 15-round body that’s permanently blocked to 10 rounds for compliance in capacity-limited jurisdictions—while preserving the familiar handling of full-size .40 S&W platforms. Built with a hardened steel liner wrapped in a durable polymer shell, this magazine offers dependable feeding, drop resistance, and long service life at a value-forward price point. Why Choose the KCI USA 10/15rd (Blocked to 10) Compliance-ready: 10-round limit in a full-size body helps meet restricted-state rules while maintaining ergonomic control and reload consistency. Hybrid construction: Hardened steel internal body supports feed-lip integrity; overmolded polymer resists impacts and environmental wear. Reliable cycling: An anti-tilt follower and heat-treated steel spring promote consistent feeding across common .40 S&W bullet weights (155–180 gr). Serviceable design: Removable floorplate simplifies cleaning after sandy training bays, rain, or high-round-count classes. Budget-smart: KCI USA quality at a price that lets you outfit a full training loadout without compromise. Compatibility: Designed for full-size .40 S&W pistols that accept a 15-round pattern magazine (e.g., Glock® 22). Also functions in compact models (e.g., G23) with extended length and subcompacts (e.g., G27) with significant extension. Not for Slimline models or non-.40 S&W pistols. Always verify fit and function in your specific firearm.

Setup & Best Practices Initial inspection: Check the body, feed lips, and follower; hand-cycle a few dummy rounds to verify smooth presentation. Function test: Load to 10; confirm seating on a closed slide, slide lock on empty, and drop-free behavior. Ammo vetting: Run your preferred practice and defensive loads; mark reliable mags (paint pen/numbering) to manage rotation. Rotation plan: Alternate magazines to even spring wear over time. Maintenance & Care Clean regularly: Remove floorplate, follower, and spring; wipe debris; reassemble dry or with a light silicone cloth. Monitor springs: Replace if you notice sluggish feeding or inconsistent lock-back after heavy use.
