I was talking to one of my boys yesterday and he said he "heard" there was a .50cal Glock. I was pretty skeptical because ive never heard of a .50cal Glock, the largest ive ever heard was either a .45cal or a 10mm Glock. I was also told that it was the same size of a normal Glock just a bigger barrel, but seeing all other .50cal guns i highly doubt that. Does these so called .50cal's exsist or are they a mere figment of some crackheads imagination? If they do exist what are they called? Glock XX? Thanks for any help in advance.
