Armscor ACT-MAG 3209 9mm Luger 17rd Blued Steel Magazine for Sig Sauer P320/M17

The Armscor ACT-MAG 3209 is a 9mm Luger pistol magazine built as an aftermarket replacement or spare for Sig Sauer P320 and M17 full-size pistols. Designed and produced by Armscor under the Rock Island ACT-MAG line, it gives P320-platform shooters a cost-effective way to keep their pistols supplied with reliable extra or replacement magazines for range training, competition, and general use.

Construction centers on a blued high-carbon steel body for strength and corrosion resistance, paired with a high-impact polymer baseplate for snag-free insertion and consistent drops. The magazine is engineered as a direct-fit replacement for factory Sig Sauer P320 magazines and is finished in blued steel to closely match factory magazine cosmetics.

This 17-round ACT-MAG fits full-size Sig Sauer P320, P250, and M17 pistols chambered in 9mm Luger, making it a versatile spare magazine for shooters who want extra capacity on hand without paying factory prices.
