Gun Lube Warning

969 Views 4 Replies 3 Participants Last post by  MACHINE
Folks, I just got this from a Firearms Instructor email list I'm on. I know the sender and he's a 100% stand-up guy and wouldn't perpetuate BS, so I thought I'd pass this on as a heads up:

I recently had one of my officers bring me his personally owned Glock 27 saying that it would not fire. After clearing it, I dry fired it and all I heard was a thud, not the normal sharp crack. Upon disassembly, I discovered the internal slide parts were coated with a yellowish green sticky slime. (There was only a very small amount of burnt powder residue inside the side by the firing pin.) I asked what kind of cleaner / lube he was using and he said he used: Pro-shot Products Copper Solvent IV

All I can say is be careful if you use this product, as this maybe the result.

As I said the rest of the gun was very clean except for the the parts being coated with this slime.

Like I said in the other thread about cleaning (where the heck did the cleaning forum go??) Glock recommends Tetra Gun Grease, and I use it, and have used it for about 3-4 years now with no ill effects, and think the stuff is the best stuff going.

Thanks for the info I'll be picking up my first glock next week. Is there any other useful info i should now about them besides using the tetra lube?

Yeah, the first time you field strip it you'll notice a copper colored residue on some parts. Leave it there, don't clean it off. It's a lubricant put there by the factory to help with break it, and it's fine.

Enjoy your Glock!!

About how many rounds does the break in period take or is it all covered in the owners manuall?
