Militec is a perfect lube for this gun. If reapplied often, it builds up and should protect parts like the rails to early wear.
About, maybe, a year ago, I met a guy, who like myself teaches a CCW course once and awhile. At one of his classes, he took a magic marker and drew a line down the short slide rails of a Glock to show his students where they should lube. It was a new gun. He then lubed it up with Militec and shot it at several range sessions.
When I saw the gun, you could still see the line from the marker. I was impressed. Really impressed.
He also told me that he had a hardball bullseye 1911A1 that he shoots for fun that he uses Militec-1 on. He claims that it makes the gun easier to clean.
I am amazed how these new lubes work. How they literally bond to the metal.
When Mobil-1 first came out, I saw some 1911A1 shooters use it on guns claiming that it didn't burn off like regular gun oil. I haven't seen that in a while, but I wonder if people are still doing it.
