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


 Sold Out 

Rock Island 1911 A2 or Para Ordnance P16 10 round .40 S&W magazine with a blued finish MGP164010B. these aren't compatiable 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 won't fit single stack 1911's. The magazines aren't compatible in the PARA USA 16.40 .40 S&W PRO CUSTOM, they take a longer magazine. Customers have told me that the magazine doesn't work in the 10mm RIA 1911 A2 without modifying the magazine feed lips. THESE ONLY WORK WITH  .40 S&W.


Please note these magazines don't have the extended base that comes on the magazines used in the Rock Island Armory 1911 A2 with the magwell. The magwell may interfere with the insertion of these magazines.


Caliber .40 S&W

Capacity 10 Limited
