I like European weapons and vehicles but I really get sick of their ethnocentrism so I had to commment. Bottom line though, The gun jammed and I highly doubt it was due to using US ammo as US ammo is top notch and it’s far more likely he was using European or Russian ammo.
I was joking at the expense of topnotch EU gun designers, of COURSE it’s not their fault.
You could be right. My .40 Jericho 941 never has jammed after a hundreds of rounds of Remingtons, Federals, Blazers or any other domestic ammo. However I picked up some Serbian Partizan .40 for the price. Got a jam every two mags. Switched back to American, problem solved.
