CMC Products POWER MAG+ follower is such that it is more stabilized and remains within the confines of the magazine tube. Of course, as the long history of all POWER MAG series magazines has proven; no other brand matches up with the complete combination of quality, reliability, service life and customer satisfaction of the CMC POWER MAG Series magazines. The most powerful and reliable 8rd and 10rd .45 cal 1911 mags, Power Mags are lean and sleek yet extra-heavy-duty with increased reliability and service life. Unique all steel follower design yields the lowest possible bearing surface for longer lasting function in dirty environments, when ongoing cleaning and maintenance may not be possible. The unique follower design, which also functions as a spring, allows the Rocket wire spring coils to be the largest; side to side, front to back and top to bottom, of any extra capacity .45 cal 1911 mags. Matte Stainless. For full size 1911 handguns.
