Tactical overview
This blued steel magazine is aimed at shooters who want a tough, affordable spare for the Sig Pro platform. Steel bodies resist deformation under heavy use and maintain feed geometry better than some softer materials. The PROMAG SIG PRO’s 15-round capacity is a practical balance for 40 S&W users who value both firepower and manageable grip ergonomics.
Compatibility and performance
Designed to fit Sig Pro pistols chambered in .40 S&W, this magazine addresses the specific needs of that caliber. The .40 S&W offers a compromise between 9mm capacity and .45 ACP terminal performance — useful for shooters seeking increased kinetic energy with controllable recoil in compact frames. The steel construction and follower design improve reliable feeding under duty-cycle conditions.
Field use and maintenance
Routine inspection and simple maintenance keep any magazine functioning correctly. Because this is a blued steel unit, watch for surface wear in high-contact areas and clean the follower and spring periodically to prevent buildup. At a price of $23.99, it’s cost-effective to maintain a small inventory of these magazines for training and operational readiness. View product details and pricing
