Something like Tetra gun grease sounds like a good compromise for your not "too tacky" use.I don't care for light oils so much for this application. Something like LSA seems good to me. If you'd prefer grease, a molybdenum disulfide grease that is not so sticky and actually works its way into the molecular structure of the metal might be your best bet. Birchwood Casey sells a spray on moly lube and you can buy it in paste form with varying degrees of tackiness, depending on the product and supplier.
The moly grease in sticks for automotive/agricultural/construction equipment is probably too tacky for a pistol. I'd be looking for a moly grease paste that is a little less tacky than toothpaste. I used to use a such a product all the time when I was working, but of course now I can't recall the brand and product names. It's not cheap, but few ounces of the stuff will last a gun hobbyist forever.
What does it say in the Manual?Does an aluminum frame with a steel slide require any special treatment such as anti-seize lubricant?
I have a custom cz75b 6 inch barrel, for target competition. It is steel on steel but it come with recommended white grease to lubricate the slide. I found that it make an almighty mess and a nightmare to clean. I was recommended to use PTFE lubricants and you can really feel the difference.Does an aluminum frame with a steel slide require any special treatment such as anti-seize lubricant?
I recall that. IIRC the Comander fired 16000 rounds, very few, if any, stoppages.Many years ago, Skeeter did a test on a Government Model, Combat Commander, and a Commander (alloy frame). The test involved many thousands of hardball factory ammo.
All 3 survived the test. They even cut apart the barrel of the Government model and it was still very usable. The Commander developed a small crack in the frame, but it continued to work just fine. Skeeter stated it had probably seen more rounds than any other such pistol. The slide stop broke on one of the guns and it continued to operate, it just wouldn't lock the slide back.
I now have 2 alloy (Commanders) a Tisas and a Ruger, both in 9mm. I put RIG on the rails after cleaning them. I have gone through a case (1,000) of 9mm this Summer. The frames still appear to be fine.
