I am 99% sure i have identified the gold colored grease thats on / in new Glocks. Im not a chemist (retired electrician), but we used it for mechanical and electricial connections in extreme heat conditions, and it was terrific for what it was intended. The description on the 1 Lb.can says: Lubricates and seals at high pressures and tempatures up to 1800 deg. F, prevents GALLING & SEIZING, and is used on all metal to metal surfaces as well as plastic etc. I called the company and talked to a female engineer, she said it was good for inital break in but not for continued use as a lubricant-IT WAS TOO ABRASIVE. I agree with some other posters to let the grease alone and when it's worn away it's done its job. (sorta like the old "brake in" oils used in cars), and then use your favorite lube. The material im describing is made by FEL-PRO, C5-A Part # 51006 Skokie Ill. 60076 This is great anti-seize material, but it should be used for what it was intended. Personal pref. is Marvel Air Tool oil, the pistons in air tools are close fitting and get hot, the last place for gummy oils and ive never had a problem with it in any firearms.

It's called "Kupferpaste" in Germany. Used for a variety of purposes including anti-seize, and also to quiet disk brakes. My '89 Isuzu pickup brakes are quiet for the first time in over 70k miles. Beats the heck out of the typical goo available in the USA. Regards, Jim Brown
Except it's not Fel-Pro anymore cause Loctite bought the company...and at least around here, none of the auto parts stores carry it. The closest I found was a silver colored similar product. I used it once and decided it was so messy, I wouldn't put it on a gun again.
My can of the stuff is so old it only says Fel-Pro. Been working out of the same can longer than I've been shooting Glocks..
