ProMag SIGA14 Compact 15rd Magazine 9mm Sig Sauer P320 Blued Steel

The ProMag SIGA14 delivers reliable 15-round capacity for Sig Sauer P320 compact pistols in a blued steel construction that withstands demanding use. This magazine extends shooting sessions while maintaining the compact profile essential for concealed carry applications.

What Makes This Different

Blued steel construction provides superior corrosion resistance compared to standard polymer magazines, particularly in high-humidity environments. The 15-round capacity maximizes ammunition availability without compromising the P320 compact's concealability. Heat-treated steel body maintains dimensional stability under repeated loading cycles, ensuring consistent feeding reliability over thousands of rounds.
