Rock Island Armory 9mm, .38 Super 1911 A2 17 RD blued MGP183817B


 Sold Out 

Rock Island Armory 9mm or .38 Super 1911 A2 and Armscor 1911 A2 FS PS 9mm 17 round magazine with the blued finish, Mec-Gar Para Ordnance P18 17 RD magazine MGP183817B. These are double stack magazines, they don't fit single stack 1911's.


Please note these magazines don't have the polymer 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. The Springer Precision base pad or OEM factory base pad 54152 will solve that problem.

The Rock Island Armory .22 TCM originally came with the Mec-Gar P18 magazines but there were modifications made to the feed lips to increase reliability with the .22 TCM. These magazines don't have the modified feed lips. While some have used these magazines with the .22 TCM with no issues most have feeding problems. The magazines were made for the 9mm and .38 Super and there is no need for modified feed lips when used with either the 9mm or .38 Super. If used with the .22 TCM there will likely be feeding problems. Don't expect the magazines to be 100% with the .22 TCM.

Note these Para P18 magazines aren't compatible with the Para P18.9 or models with the magwell. The Para Pro Custom 9mm with the magwell takes a different longer magazine.
