Rock Island Armory 1911 A2 .40 S&W 10 RD Blue Mec-Gar MGP164010B

Rock Island 1911 A2 or Para Ordnance P16 10-round .40 S&W magazine with a blued finish MGP164010B. These aren't compatible with the 10mm. If your pistol has a magwell/funnel, the metal base plate on these magazines may prevent insertion; they don't have the extended base pad. These are double-stack magazines. They WILL NOT fit single-stack 1911s. 

The magazines ARE NOT compatible with the PARA USA 16.40 .40 S&W PRO CUSTOM; they take a longer magazine. Customers have told me that the magazine DOES NOT work in the 10mm RIA 1911 A2 without modifying the magazine feed lips. THESE ONLY WORK WITH .40 S&W.

These magazines do not have the extended polymer base that comes with the magazines used in the Rock Island Armory 1911 A2, which features an extended magwell. The magwell will interfere with the insertion of these magazines. The magazine requires the Armscor extended base pad,part number 54152.

***Please note these magazines don't work with 10mm ammo; they are only reliable for feeding the .40 S&W.
