Unless you get one of the P320's that's inclined to set itself off
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.
