I'm putting my 2 cents in on that. For polymer pistols it is HK and Glock for reliability. HK and Glock have been doing polymer for how many decades? Go back to the HK USP, if not before, and Glock has been doing the polymer thing since 1985.
H&K made a polymer Hi-Point prototype in 1970. It was called the VP70z.
