Armscor logo Rock Island Armory / Citadel 1911 Officers .45 acp 7 round ACT-MAG magazine with a blued finish. ACT-MAG 1911 magazines are used as OEM magazines by S&W, Rock Island Armory, STI, Night Hawk, Spartan, Charles Daly and others.
Now you can use the 8 round 1911 magazines in the 1911 Officers giving you an 8 round magazine with a finger grip. Below is some information on the X-Grip and I have more information in the X-Grip section.
The XGRIP 1911c 2pc is a NEW magazine adapter offered by FDI for the 1911
compact. The XGRIP 1911c enhances the versatility, look, and feel of the gun.
Size of a Compact, Capacity of a Full-Size
The patented XGRIP 1911 2 piece adapts the full size Colt .45 acp 1911 8 round magazine with plastic floorplate to function and blend into the frame of the compact 1911 Officer pistol.
Some also use the ACT-MAG 1911 7 round officer magazines in the Kahr CW45 as shown below, they seem to work fine. However they aren't actually made for the Kahr CW45.
