I just noticed that my milspec 1911 pistol came with a coupon that allows me to buy mags at a greatly reduced price. The standard 7 round (GI Im assuming) mags are only 9 bucks each, and 10 rounders are only 14.50. Anybody have experience with these mags? Comments on quality? Its a ten mag max on each type of mag, I am considering picking up 10 7 rounders and maybe a couple 10 rounders.
