Metalform Magazine Ar-15 9mm - 10rd Blued Steel Colt Style

The Metalform Magazine AR-15 9mm - 10rd Blued Steel Colt Style is a purpose-built magazine designed for shooters running 9mm conversions on AR-15 platforms. Whether you're training with a suppressed SBR, setting up a cost-effective duty backup, or building a competition carbine, this magazine delivers the reliability law enforcement and military operators demand. The 10-round capacity strikes the balance between capacity and manageable ergonomics, making it ideal for both confined training environments and shooters in restrictive jurisdictions.

Manufactured from blued steel, this Colt-style magazine uses time-proven mechanical geometry to ensure consistent feed reliability with 9mm projectiles. The blued finish provides corrosion resistance while maintaining a professional, mil-spec appearance—critical for duty and duty-adjacent applications where finish degradation affects asset accountability. The welded baseplate and stamped body construction handle repeated loading cycles without performance drift, and the witness holes allow rapid capacity verification during tactical reloads or administrative handling. At 0.35 pounds, the magazine remains lightweight enough for extended carry on plate carriers or load-bearing equipment without fatigue.

This magazine is purpose-matched for Colt-spec 9mm AR-15 uppers and dedicated 9mm lower receivers, as well as most mil-spec AR platforms equipped with Colt-compatible magazine wells. Operators running suppressed carbines, precision rifle courses, or transitioning to 9mm for ammunition economics will find this magazine's consistent feeding geometry and robust construction essential. Stock multiple units for training blocks, duty rotation, or to ensure you maintain adequate spares—feed system reliability is force multiplier, and Metalform's reputation in tactical circles reflects years of producing magazines that perform when lives depend on them.
