I use gallons of WD-40 myself on all kinds of things, but I only use it to clean my guns and wipe them down. For lubricating I use Castrol Syntech.

You use engine oil for your guns? I use Castrol Syntec German formula in my GTO, but I used Spec 308 and Spec 357 on my Glock. 308 for the slide rails and a drop of 357 to rub down the outside of the barrel and the inside of the slide. A total of two small drops of the 357 and 308.

But, for light stuff, like maybe .22s, maybe it would be okay. But again, the whole "sticky residue" puts me off.
If it works for you, then it's okay for you...hard to argue with that.

I was told by a gunsmith that it leaves a residue on a gun that will cause problems in areas like the trigger group. I'd use something made for the purpose like Essox (sp?) - slickest stuff known to man.

If you read Wikipedia's article on WD-40, you will find that of all it's intended purposes listed, firearms maintainence is not one of them. It was intended to be a water displacing penetrating lubricant, which it does well, too well. So well in fact, that I wouldn't stake my life on it. With so many products designed specifically for guns, why use WD-40?

WD40 will leave a residue and gum up if not cleaned completely out once in a while. Locksmiths worn against it for this reason. Perhaps your cleaning habits avoided this. Should you take a chance?...

I use Mobile 1 motor oil after reading about it in several different locations. It is slick stuff and is designed for heat and abuse. I could tell a definite difference right away. Cost effective too as you only need a drop at each lube point. A quart will last a long time and it won't 'run off' in short order like thinner oils sold just for guns. I used to spend a minute fortune on REM-OIL. I foresee the Mobile 1 lasting me at least a couple years.

I'm in the camp of pgrass101, but I first use Hoppe's powder solvent, then WD-40 to pick up the remaining solvent and anything the solvent missed, then wipe it all down with Hoppe's gun oil. Of course, I like cleaning and tinkering with the pieces. I don't mind taking 15 minutes to do the multi-step process... some folks would consider this borderline obsessive-compulsive... haha.
