Rock Island Armory 1911 A2 .40 S&W 15 RD NICKEL MGP164015N


 Sold Out 

Rock Island 1911 A2 or Para Ordnance P16 15 round .40 S&W magazine with a nickel finish MGP164015N. If your pistol has a magwell/funnel the metal base plate on these magazines may prevent insertion. 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 slimmer 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.

Well, they say these don't fit with a funnel, and they are correct. They also do not cycle as-is in the 10mm RIA. HOWEVER(!), since the polymer base mags are sold out with no replenishment in sight, these WILL WORK if you are handy with a file or an angle grinder and have removed the funnel. Compare the feed lips on these to one that came with the gun; these have longer lips. I used an angle grinder to remove material and cleaned it up with a 600grit file. Cycles just fine now. I gave it 4 stars only because of the modification, but it is worth 5 stars.
