In a shooting world where the word “polymer” brings quick images of “Glock,” it’s easy to forget that the first viable commercial polymer pistol was actually made by Heckler and Koch (HK). Well now it seems like they have moved on to their fourth gen offering in combat tupperware, and you may just be able to buy this one.
In the late 1960s, firearms engineers at HK came up with a gun that was to be a cheap Volks Pistole (or People’s Pistol) that could be issued to West German police and military. A simple blowback gun, it used high impact advanced plastics for its frame and was known as the VP70 when placed into production. (However, in an installment of good-old-fashioned American know-how, keep in mind that the first polymer framed firearm was the Remington Nylon 66, designed in 1959, but it was a .22 rifle, not a 9mm pistol).
However the VP70 never really caught on and, when that gun went out of production in 1989, HK started its design on a gun called the USP (Universale Selbstladepistole or “universal self-loading pistol”), which is still in production today as the company’s principal hammer-fired polymer framed gun, augmented by their P2000 variant which could be considered HKs gen 2.5 model.
The third gen of HK polymer is the super-advanced P30, which is arguably at the top of the food chain as far as these types of guns go– but it’s kinda expensive at around $1200.
Now it seems that the company has produced its 4th generation of polymer pistols– and they have gone back to being striker-fired.
