CMC’s higher quality and innovative designs are very unique. CMC mags are held to higher controlled tolerances that are 75% tighter than the decades old 1911 military spec common among all generic re-labeled 1911 magazines. Dating back to 1986, the original follower design as used in CMC and Shooting Star magazines has been the only follower design used in all CMC magazines because of one simple fact – they worked. The design was born with a specific set of objectives; to offer the most serious types of shooters the very highest levels of reliability in every area of function, and longest possible service life. All of CMC follower designs purposely jump forward at the point of engaging the slide stop upon last shot fired, in order to obtain appreciably more engagement to the slide stop than any other fully retained design. The importance of that function (slide lock upon last shot fired), especially with law enforcement, military, self defense and even competition applications is that it offers the most reliability for locking the slide open and signaling to the shooter that the weapon is empty; an extremely important feature for those who use their weapons as serious tools.


Per their website, CMC maintains the POWER+™ magazine has a follower design that is more stabilized and remains within the confines of the magazine tube. I will confess I did notice that CMC’s all steel followers are superior when compared to other plastic followers (like Wilson Combat) in that they never wear out, are impervious to heat and have virtually unlimited service life. CMC’s unique follower designs require minimum of bearing surface contact to the inner walls of magazine. This diminished surface yields greater margins for continued reliable function when used in poor shooting environments, and/or when cleaning and maintenance is not practical. All of CMC’s unique follower designs are such that the followers themselves are also springs, yielding additional strength to that of the common coil type spring that all 1911 magazines incorporate. CMC’s follower designs allow for each of the “Rocket” wire spring coils to be wider and longer in coil design throughout the length of the spring, yielding superior spring strength by design as compared to any other brand of extra capacity 1911 magazines. The combination of CMC’s follower (a spring itself) and larger spring coil designs yields more strength in any given length of magazine tube.


About the only thing I noticed that is a potential “con” with CMC’s POWER+™ magazine is that, aside from the overall length from the 10-round capacity, is the follower. While yes, CMC maintains their follower is superior in strength, I just don’t like that the follower itself doesn’t fill the magazine tube at the top. My fear is that in the process of dropping the magazine or crawling through terrain something will get forced down into the space and tube. While I do like that Wilson Combat magazines have a full plug plastic follower, its gain is indeed offset by CMC’s follower that is stainless steel for improved durability. So it’s really just a matter of preference. Separately, the base plate on the bottom of the magazine seems clunky and would probably be best redone in something more streamlined or perhaps as a singular block. Aside from those two, I didn’t find any other failures in the magazine despite several hundred rounds through it (although I did find a problem in my 1911’s ejector).
