Educational Zone #94 – Product Evaluation – Magnalube-G Grease

I was recently asked to try a new grease that can be used for firearms.

It is called Magnalube-G.

It is made by Saunders Enterprises, Inc and they sent me a few .75 ounce tubes.

Here it is.


It is labeled as a “PTFE Grease”.

PTFE is Polytetrafluroethylene and microparticles of PTFE are suspended in Magnalube®-G to ensure continued performance of equipment operating at high loads and extreme temperatures. That simply means that although the grease is made to operate in temperatures from -35 degrees to as high as 458 degrees, if the petroleum base of the grease should burn up, the PTFE remains on the equipment to continue to serve as a lubricant.

This product has been a specialty lubricant for over 30 years, but was just recently discovered as a great firearms lubricant. They asked me to evaluate the product and do an evaluation of the application on firearms.

Many years ago, I sent a Browning HiPower to Cylinder and Slide for a trigger job. They did a fine trigger job on my pistol and included a piece of literature that described the advantages of using a grease on firearms, especially semi-auto pistols. The main issue was that although a good quality oil will lubricate just fine, if you lay the pistol down or carry it in a holster, the oil will tend to drain from the area where it was applied and leave important areas without enough lubrication.

In contrast, a high quality grease will stay right where you put it and will not drain away from critical areas. I have been putting grease on the slides and rails of my semi-auto pistols for many years, with very satisfactory results.

I began to use Magnalube-G several weeks ago and have been very satisfied with the results.

I clean my pistols after shooting and basically remove all lubricants.

This means that I must re-lubricate them after cleaning.

Here’s how I have used the Magnalube-G grease.

I apply a small amount on the critical contact points between the slide and frame on my 1911 pistol.


I then spread it out evenly.


I also put a small amount on the hammer, where it rides on the slide.


One of the more important areas is on the locking lugs on the barrel.


Again, I spread it out evenly with my finger. 

Only a very small amount is needed.

If you put too much, it will just be wiped away and although it does no real harm, it is unnecessary. 

The Magnalube-G is a green color, but as the engineer I spoke with told me, “If you can see the color, you are probably using too much.”

Of course, this is an advantage for us as customers, as a little will go a very long way.


A tube will last most shooters a long time.

I spread it around slightly and then reassemble the pistol.

I rack the slide a few times to spread the grease out evenly and then wipe off any excess, which may appear at the rear of the slide.

On my AR15, I used a small amount on the bolt locking lugs.


Once again, I spread it out evenly with my finger.


And also a small amount on the hammer where it rides on the bolt carrier.

I run the bolt and bolt carrier “wet” with lubricating oil and have had very good success with that system.


And spread it evenly.


On a Glock, I apply a small amount on the four metal inserts on the frame where the slide rides.


Spread it evenly.


And assemble the pistol and rack the slide a few times to spread the grease evenly over the surfaces.


You can see how the excess gathers on the rear of the slide and can then be wiped off.


Of course, the proof is at the range. 


My pistols have run very well, and I see no problems whatsoever with this grease. It is soluble with petroleum solvents, so my usual cleaning will remove any from the pistols and require re-application after cleaning.

Magnalube-G is available in .75 ounce tubes and also larger amounts, if desired. The cost is less than $5 a tube, and as noted, a tube will last a long time.

You can order it from their Internet site here: Magnalube-G Grease.

This seems like a great product to me and I would recommend it to my friends here on
