Chip McCormick Power Mags 10 rd or 8 round, black
10rd POWER MAG .45ACP Stainless Steel M1911 Magazine
The most powerful and reliable 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 .45cal 1911 mags.�
COMBAT PROVEN! The most elite of customers and the test of time continue to prove no other 1911 mags match all of the performance advantages of Power Mags!
Do not use the 10 rd in Officer size frames, Select the 8 rd Power mag for Officer Frames. The reason is if you use the 10rd in an Officer Frame there is no "Over Travel Protection" since the base of the mag does not reach the frame of the gun and have the upward travel stopped by the frame. So if I aggressively slam the mag in and it jumps past the magazine catch it can hit and break the ejector. You may not do this on the range but in a fight with it all on the line you can put your weapon out of commission if the ejector breaks, do not risk it.
