USPc mag spring question

[chilic82]

Are the factory springs that bad? Do you just stretch them a little or buy new one's. I can't believe HK would let this problem just ride if they are really that weak.

No, they are not. Short answer is they are not bad unless of course, they are. I have dozens of USPC .40 and .45 mags and have yet to get a bad spring. But many have and when you get a bad one, there is no cure. Stretching it will cure it for a moment or two but it will quickly go back to malfunctioning again. The only cure is to replace them, and IMO if you need to replace them you should use the Wolff +10% power springs. But if the springs are working, as all of mine are, why replace them?
