The first striker- fired pistol on a Polymer- frame was not the Glock, it was the Heckler& Koch VP 70:
The Luger, P 38 are alright, but the first reliably working semi automatic pistol was the Borchardt C 93 dating back to 1893. Basically the great grandfather of all selfloaders and the father of the Luger.
Regarding the P 38:
I see the Walther PP as one of the breakthroughs. The P 38 was a kind of step back in the field of ergonomics ( seperate levers for disassembly, safety, slide release, magazine release at the bottom of the grip) where as the PP and PPK series were already decockable via the safety lever. And their mag release was on the side of the grip.
1911 of course and the HP......owned both of them.........too many guns to handle in this single thread.....
