Magpul PMAG 17 P320 9mm Magazine - Stainless Steel 17rd SIG

The Magpul PMAG 17 P320 delivers enhanced feeding reliability and extended capacity for SIG Sauer P320, M17, and M18 pistols. This stainless steel magazine addresses common feeding issues while providing 17 rounds of 9mm capacity across full-size, compact, and sub-compact configurations.

What Makes This Different

Unlike standard factory magazines, the PMAG 17 P320 features Magpul's proven polymer construction with stainless steel internals for corrosion resistance. The anti-tilt follower design reduces misfeeds by 40% compared to conventional followers. Four-way anti-friction coating on internal components ensures consistent feeding through thousands of rounds.

Key Features

• 17-round capacity in 9mm Luger with reliable feeding geometry
• Stainless steel spring and internal components resist corrosion
• Anti-tilt follower prevents nose-diving and double-feeds
• Compatible with P320 Full-Size, Compact, and Sub-Compact frames
• Drop-free design with textured floorplate for positive grip
• Fits M17 and M18 military contract pistols
