My 1994 G19 slide does not rust. Period. And that is the major reason I like Glock. I was recently pondering getting a G23 and I ran across the rumor/fable/fact that "new" "made in USA" Glocks no longer have the Tennifer finish due to EPA/Aliens/Area51Conspiracies and that they rust. Again, I already know that Tennifer finished Glock DO NOT RUST, and they never miss a beat, etc., etc. so I'd really like to focus on the rust issue with made in USA, non-Tennifer finished, Gen-whatevers, Glocks. I keep using search functions and I can't get answers. I've seen a YouTube video of rust on a slide - but it is a short crummy video - a no talkie, so not much info and for all I know it could be peanut butter from the guy's lunch box. So do the new ones rust?
