NOTE to the Mods: I had difficulty picking the right forum to put this thread. I hope to not receive yet another infraction for posting in the wrong section, lest I be banned due to this conundrum. I feel as if I’m walking on eggshells every time I post a new thread; “maybe the mods will think this belongs in a different section?” is always on my mind and frankly causes a lot of stress. So many grey areas and arbitrary confusion. Thank you and I apologize profusely if I have erred against your power.

Friends, shooters, this concerning OTHER BRANDS such as Berettas, SIGs, etc. that have alloy framed pistols in their lineups. I feel as if I must state this, because I don’t wish to exclude various alloy framed S&W pistols, but feel as if I must in case a moderator wishes to ban me outright for posting “in the wrong section” as mentioned above.

So, in a nutshell, does an anodized or otherwise coated aluminum frame, be it rifle or pistol (but NOT S&W guns as this thread would need to be in a different section) need to be lubricated on the exterior surfaces for any reason? For example, I own a SIG alloy frame pistol but prefer to keep the exterior dry and free of oil to keep it from being at all slick when I pick it up or draw.

Isn’t bare aluminum essentially free from corrosion in our atmosphere due to self-passivation? This is were a very thin layer of grayish aluminum oxide forms on raw aluminum, which prevents further corrosion from oxygen in the air. Not only that, but the anodizing should make it doubly less likely to corrode, which it already essentially cannot anyway even if bare?

I’ve read of people who keep a thin layer of oil or grease all over the firearm, their reasoning often be justified by lines such as “that’s the way muh daddy taught it to me” or something along those lines. But, if there’s a compelling scientific reason to lube the EXTERIOR of anodized aluminum guns, I’ve yet to hear it.

Anybody else agree or have thoughts? Thanks!

Good question. On my Beretta 92's and SIG P220's, I typically wipe the who gun down in a light coating of Ballistol, then wipe the excess with a clean rag. Seems to work. I think the anodizing on top of the aluminum does protect it from corrosion.
 
Plain aluminum in the air would soon look like an old screen door: messy black with aluminum sulfide.
Finished aluminum, like on firearms, is anodized to protect it from reacting with the atmosphere. Just clean the anodized surface gently and otherwise leave it alone except for lube on friction points.
Harsh cleaners or scrubbing will remove the anodizing and ruin the finish.
 
Anodized aluminum receivers require lubricant on friction points, but that is all. Anodizing creates a hard, aluminum oxide layer on the surface and it also slightly penetrates the surface, preventing any corrosion.
