Hello from snowy Afghaninstan. I'm deployed here on a mission training and assessing Afghan Police. During some periodic quick reaction drill training, the Staff Sgt running it told us in a perfect world, we should rotate our magazines to destress the springs. However, since most of us were not issued enough magazines to do that (I was only issued 3 M9 and 7 M-16 mags), we should periodically take out mags apart and stretch the springs out by hand, ie, pulling on them. At home, I do rotate my mags, though I know many people say it's unnecessary, due to the fact that the springs are never compressed past the point at which they can warp (I think it's called the spring constant, or 'k,' in physics). One of my M-9 (Beretta 92) mags is an Airtronic, which I believe gave troops in Iraq a lot of problems. The other two are Check-mate. Bottom line: I've never heard of stretching out mag springs by hand in 10 years in the military, along with the same amout of time shooting recreationally. A lot of bad "gouge" gets passed around the FOBs. Is this something I should be doing? Thanks in advance for any help from the experts.
