#4 – Glock Pistol

Having originated in Austria in 1982 the Glock pistol has since gone through four generations and today accounts for 65% of the small arms used by US law enforcement officials. Apart from its comparatively late entry into the world of weaponry, the Glock also stands apart in that it is the first widely used pistol to be made of polymer moulded by injection. This 17-round gun inaugurated the era of polymer guns which have superior durability and, at least in case of the Glock, superior range as well.
