blowback pistol slide lubing

[Kak543]

I own a Umarex SA10, I read on CO2 guns it's better to only use silicone based lubricants. Silicone oil it's not a good lube for metals so I used silicone based grease on the slide.

It seems to work, but then other people told me to avoid grease since it creates gunk and mix with dust creating an abrasive compound".

This grease is quite thick but stays fluid with time, does not become dry gunk and seems not to trap much dirt.

Gun works well, there's a bit of minor wear on the slide (I'm around 2500 rounds) but everything seems fine at a first look... At the same time I'm not sure this grease is "soft enough" , racking the slide gives a "like rubber" sensation...

What do you use?

Plain old gun oil. Charles

On that gun the CO2 system is in the magazine. For the magazine you can put a drop of silicone oil on the tip of the CO2 cartridge every few cartridges, or you can use Crosman Pellgun oil (which is nondetergent motor oil if you read up on it).

Use whatever you want in the gun. Too thick and/or too much of a grease can slow down the slide as the CO2 pressure drops. I personally use ALG Go-Juice 0000 Very Thin Grease (a firearms lube); it's thicker than oil, but thinner than grease. You don't need a lot of lube.

On slides I use synthetic grease: super lube (ptfe) it's clear no color. Good on lots of things all It doesn't run out like oil. Safe on seals.

I don't know why silicone base oils on CO2 guns. There is no chance of dieseling. Maybe inside the operating system it would be better for seals, but everywhere else, metal to metal use a good gun oil or motor oil.

I just put a dab of Moly on with a Qtip.

This Lucas Gun Oil is inexpensive, a little goes a long, long way and it's the best I've used for metal on metal, moving parts(frame to slide on my 1911's). It bonds with the metal at the molecular level for lubricity and longevity. There are a plethora of similar, great products. I just like this one best.

I prefer lithium grease. Clean, effective and doesn’t drip all over the place. Works well on model railroad axles too.
