I think with factory mags, that whole spring fatigue thing may be a myth. I always carry full mags, and one in the pipe. I do take my magazines apart now and then and clean them throughly and lubricate them slightly.
They once found a cache of WWII vintage 1911 magazines, fully loaded with ball ammo. they test fired the stuff, not one failure to feed, so that speaks to the spring fatigue issue, and not one misfire, speaks to the quality of stuff built in WWII
Meanwhile they have apparently displayed 100 New Special and Limited Edition Pistols and Rifles at SHOT. Including the new EXTREME! Line......Woof.....
I have no doubt the EXTREME! 9mm 226 is far more lethal, desirable, accurate, and costly then the Blackwater 226. Oh how the mighty have fallen. New Hampshire State Police are getting ready to select new pistols. I wonder is SiG will just give them a few hundred. How embarrassing would loosing that contract be.
