Hello everyone, I am a new Range Officer Operator owner. My wife just got it for my birthday. My question is, that in the gun case, besides the traditional papers, there is the "1911 Loaded Coupon" were you can buy extra mags at very reasonable prices. Do you recommend the 7 round "blued" mags or the 7 round "stainless steel" mags? Thank you for any opinions regarding the different type or maker of mags.
