When did they stop using Tenifer.
I haven't talked to anyone who could get a straight answer from Glock on that. My Armorer certification has expired, so I haven't had a chance to find out for myself.
I'd say anything with USA stamped on the slide has very little chance of having Tenifer. Those I would definitely stay away from.
4th Generation guns are suspect in my opinion, regardless of the country on the slide.
