ProMag RUGA21 15-Round Extended Magazine 380 ACP Ruger LCP Steel

The ProMag RUGA21 Standard magazine transforms the Ruger LCP's capacity from 6 rounds to 15 rounds, providing more than double the firepower in a reliable extended format. This blued steel construction magazine maintains feeding reliability while extending grip length for improved control and faster follow-up shots.

What Makes This Different

Unlike polymer alternatives, the RUGA21 features heat-treated blued steel construction that resists deformation under pressure and maintains consistent spring tension over thousands of loading cycles. The extended body adds 2.5 inches to overall grip length, creating a full three-finger grip that dramatically improves control compared to flush-fit magazines. ProMag's proven follower design and music wire springs ensure consistent feeding across various 380 ACP ammunition weights and profiles.

Key Features

• 15-round capacity increases firepower by 150% over standard 6-round magazines
• Heat-treated blued steel body resists corrosion and maintains dimensional stability
• Extended grip length provides full three-finger purchase for enhanced control
• Music wire springs rated for over 10,000 compression cycles
• Anti-tilt follower design prevents feeding malfunctions and double-feeds
• Removable floorplate allows complete disassembly for cleaning and maintenance
• Compatible with all Ruger LCP and LCP II pistols chambered in 380 ACP

The extended magazine proves particularly valuable for concealed carry applications where reload opportunities may be limited. Competition shooters benefit from the reduced reload frequency during steel challenge and practical shooting events. The additional grip length transforms the LCP's handling characteristics, allowing for more precise shot placement and faster target transitions. Weather resistance remains excellent thanks to the blued steel finish and corrosion-resistant internal components.
