Me? No. Well, unless you count reloads. But I vet everything I carry and preferably carry something with a decade or more of service history behind it.
But I absolutely do not rely on "design" or manufacturer data. Nobody doubts Glock is a good product, but nobody who knows shit denies that they've had some bad roll outs. Their neat little single stack that had to be redesigned to feed reliably, Gen 3s that choked when a weapon light was installed on the rail, the 17M issues...plus manufacturers lie and cover things up. P320?
