Armscor Rock Island Armory 9mm or .38 Super 1911 A2 and Armscor 1911 A2 FS PS 9mm 10 round magazine with the blued finish, Mec-Gar Para Ordnance P18 10 RD magazine MGP183810B. These are double stack magazines, they do not fit single stack 1911's.
Please note these magazines do not 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.
The Rock Island Armory 22TCM originally came with the Mec-Gar P18 magazines but there has been modifications made to the feed lips to increase reliability with the 22TCM. These magazines don't have the modified feed lips. While some have used these magazines with the 22TCM with no issues many 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 22TCM there may be feeding problems. Don't expect the magazines to be 100% reliable with the 22TCM.
Note these Para P18 magazines are not compatible with the Para P18.9 or models with the magwell. The Para Pro Custom 9mm with the magwell takes a different longer magazine.
THIS MAGAZINE IS ALSO COMPATIBLE WITH THE BUL M5 IPSC 9MM (WILL NOT INSERT PROPERLY IF THE PISTOL HAS AN EXTENDED MAGWELL), ROCK ISLAND ARMORY 9MM 1911 A2 AND ARMSCOR 9MM 1911 A2 FS PS. I HAVE BEEN TOLD THAT THEY WILL ALSO WORK IN THE BUL M5. HOWEVER, THE MAGAZINE CATCH HAS TO BE ALTERED, WIDENED A BIT.
Caliber 9mm or .38 SUPER
Capacity 10 Limited
Carbon Steel Tube, heat-treated for strength
Higher tensile music wire spring
Removable steel butt-plate
NOT COMPATIBLE WITH PARA PRO CUSTOM P18.9 PISTOL
If using in a Armscor 1911 A2 with the extended magwell you will need an extended magazine base pad. This is the the Armcor factory extened base:
Constructed from certified carbon steel and features a heat treated housing and high-impact polymer or certified carbon steel follower and floorplate. The magazine spring is made of high strength type "D" music wire-the strongest wire available. TIG welding provides additional strength and a seamless finish. Each magazine surface is specially treated to ensure high corrosion resistance.
