I am very happy to get half this gun taken apart and replaced after this video. This gun is a giant overpriced marketing scheme and Sig should be ashamed of itself. It's pretty sad to see a "top tier" firearm manufacturer release such a dogshit product to the public. At least it was reliable, so it didn't TOTALLY suck.
