I'm also thinking "there's polymer and there's polymer". this Kahr frame, you can wiggle, squeeze, and deform the frame rails all over the map. **** with my old crippled fingers I CAN SQUEEZE the top of the rails and move them in 1/8--3/16!!!!!
Ummmmmmm pretty sure there's still a steel frame in there..... right? I've not looked at them all, but every polymer frame gun I've seen has a steel or at least aluminum insert that the rails actually ride on.
FYI, if aluminum and steel are riding on one another, steel will be what wears if it's type 3 anodized aluminum.
