There may be something happening here that's beyond S&W's control but I've been waiting over five months for replacement springs for some M&P 14 round .45 magazines that bent the first time I loaded them. I've contacted S&W numerous times, same reason always given-they are on order, just not yet available.(thats when they bother to reply or call back!) I'm having trouble believing that they can't come up with three magazine springs. I don't know about anyone else but had I sold something to someone, I'd have made it good long ago, new magazines, money back, something, anything to not cause hard feelings with a customer.
