As everyone else - including yourself - has retorted on this site (and others) every time I mention price as a consideration, I will in this case likewise ask you question, what price do you put on your life?

The stainless steel magazines will not rust, corrode or deform under the tension of the spring. They are currently about $14 each from CDNN. CDNN sells PMags for about $10 each. Gander Mountain has PMags for $14 each (no shipping charge, of course, but you do pick up a sales tax). Are you really saying that $4 a magazine is worth betting your life on the "creep" of plastic under constant strain?
