That feature allows for some of the extra capacity to be accommodated by allowing the bottom of the spring to extend below the bottom of the magazine tube, into the polymer base, while still allowing the magazine to be seated easily. The magazine body length is also a bit longer than that found on some other magazines. The next picture shows a top view of the followers, with the Check-Mate on the left, composite in the middle, and original style on the right. The picture below features an original style follower from a seven-round magazine on the left, followed by a hybrid composite/steel follower, and the patented Check-Mate bullnose follower on the right. It also allows the front edge of the follower to impact the frame feed ramp, which can cause damage when used in alloy-frames (aluminum) pistols. This may bind up the magazine, requiring that it be pulled out of the pistol, rather than dropping free. That design (along with it's corresponding magazine spring) allows for an eight round capacity due to the "collapsing" feature, while the front skirt is an improvement over some earlier eight-round follower designs (such as the Devel style follower), which can rock forward as the last round in the magazine is fed. They also include Check Mate's patented bullnose follower, a design that has both a "collapsing" top and a skirted front. These include numbered witness holes on both sides of the stainless steel magazine bodies robust, removable bases that both protect the magazines when dropped and allow for positive seating of the magazine when used in 1911s with extended magazine wells. The two magazines received are very good looking, well designed magazines, with a number of features. Next is a newer design seven-round magazine with a hybrid composite/steel follower, with an eight-round magazine (also utilizing a hybrid follower) on the far right. The picture below shows, from left to right, one of the Check-Mate magazines, followed by an older design seven-round magazine. Other magazine design changes made have been to increase the magazine capacity, like the Check-Mate eight-round magazines that are the subject of this article. The newer designs were developed to release the round earlier, which allowed newer ammunition designs such as semi-wad cutters and some hollow-point designs to feed more reliably.īelow is a photograph showing the three basic magazine designs found in 1911 magazines: The wadcutter magazine features parallel feed lipds that open comparatively abruptly to full width, providing release of the cartridge earlier in the feed cycle than the traditional GI magazines.Ī third variant is a hybrid of the first two, featuring tapered feed lips at the back of the magazine but also incorporating the early flare-out and release of the wadcutter syle magazines. A new design was developed, which is cleverly referred to as “wadcutter” feed lips. However, wadcutter bullets don’t feed well from the GI-standard magazines with tapered feed lips. One of the ammunition types favored in bullseye competition is the wadcutter bullet design, which has a flat “point.” Wadcutter bullets cut nice, clean holes in the target, making scoring easier and more accurate. Those had tapered feed lips, which release the round relatively late in the feed cycle. The original military and commercial magazines were designed to feed 230-grain ball ammunition (like the Colt seven round magazines). And for a long time, you could get them basically one way blued, and with a seven round capacity.Īs time passed and ammunition choices expanded, manufacturers began developing magazines with different feed lip profiles. But first, a little information about 1911 magazines in general is in order.ġ911 magazines have been around, well, since about 1911, which is a long time. received a pair of Check Mate 1911 magazines for our evaluation and review, which we'll get to presently.
