PSA is selling the 92fs for $449 with free shipping. I'm dangerously close to ordering one but I have a question. I understand a few parts are made of polymer. Trigger, slide safety, guide rod and mag release. Did these parts used to be made of steel? My dad has an older 92fs (maybe 20 yrs old). I really like that pistol and I don't remember it having plastic parts. I may be wrong about that. At any rate, are the newer polymer parts cause for concern? Is this standard with all 92's or could this be a cost reduced civilian thing?
