Ive been looking for this article but i cant find it anywhere. It was from a few years ago and they did a torture test to a XD40 and a 40 cal Glock(not sure which one exactly). It included firing a few thousand rounds after beign dropped, wet, frozen, muddy, sandy, and anything else you could possibly think of. I was surprised how well both of them did. I dont remember exaclty how may malfunctions each had but i do remember they were both below 10 and the XD had 1 or 2 less then the Glock. I was just very surprised how reliable both guns are. I hope my new XDM is just as good as my old XD used to be. It was time for it to retire.
