The KCI USA 10/13rd Magazine for Glock® 23 uses a standard 13-round body that’s permanently blocked to 10 rounds for California-compliant capacity, giving you dependable function, training value, and full-size handling—without running afoul of local regulations. Built from tough black polymer with steel-reinforced feed lips, a heat-treated spring, and an anti-tilt follower, this mag is engineered for smooth feeding and consistent lock-back in compact Glock .40 platforms. Why Choose the KCI USA 10/13rd (Blocked to 10) for Glock 23 Compliance-ready capacity: 10-round limit in a duty-size body meets many restricted-state laws while preserving Glock 23 ergonomics. Proven construction: Impact-resistant polymer shell with steel reinforcement at critical feed points for durability under high round counts. Smooth, consistent feeding: Anti-tilt follower and tuned spring tension support reliable cycling across common .40 S&W bullet weights (155–180 gr). Easy field service: Removable floorplate enables quick cleaning after dusty bays or long training days. Great value: KCI USA offers cost-effective performance so you can stock up for classes and practice without overpaying. Compatibility: Designed for Glock® 23 (.40 S&W, compact). Also works in Glock 27 (will extend past the grip) and Glock 22 (shorter mag will seat; does not sit flush). Not for Slimline models (G43/43X/48) or 9mm/10mm/.45 ACP pistols. Always verify function in your specific firearm.
