Sig Sauer

A very accurate, well made, over hyped and overpriced brand of handgun. Comes in almost every pistol caliber imaginable. Do yourself a favor and get the cheaper, more durable and just as accurate Glock.

You spent how much on a Sig Sauer? Shit, for that amount of money you could've bought two Glocks!
