Well, the winner in this category is once again....the Glock. When it came out in the eighties it was unique. Think about it. If it came out in 2001 would it have been so successful? No way.
I must give Gaston Glock credit....his timing was pretty darn good but there's really nothing special about his pistol. He's sittin' on a beach somewhere, sippin' a umbrella drink laughin' his a** off
