Stainless will tarnish and even rust if subjective to harsh conditions. The old (but not really old) Glock finish (the shiny black) coupled with the rear tennifer treatment is pretty astounding with regards to rust prevention.

I have a Springfield Loaded that is all stainless. Not much of a fan, though it's hard to say why. The machining is very rough, and the stainless probably shows that more than a coated steel gun might. :dunno:

Others I have are partly stainless, like the slide on the P229 (which is still has a black finish) and a P938 that is stainless "in the raw".
