Have you tried waxing the insides (and outsides for that matter) of your magazines?
Disassemble the mags, degrease the inside/outside, apply a coat of automobile wax, let dry, buff it off and repeat. The surface will be slicker. And more protected from moisture/sweat than just from oil alone.
Not my idea, got it here, tried it, it works.
Mine isn't a need to make it slicker but it still does that. My need/desire was to do more to insure the magazine didn't rust on me. I come in from yard work and the sweat (or rain, or back splash from the high pressure washer) has moisture beaded up on the magazine in the pistol and in the mag. pouch on my other side. I'd have to dry them off good and reapply a coat of oil with the trusty old oily rag I wipe guns down with. After waxing (2 coats with Nufinish car wax - other brands would work fine, I just happened to have some of that in the mud room) I come in from outside, remove the magazines and wipe them off with a paper towel and they are streak free and shine like a new out of the wrap magazine. No rust all summer and no oiling of the magazines for the P01. Yeah, still hade to wipe the gun down with the oil rag.
Try some wax on one magazine and see if it makes it easier to load. It does with blued magazines and brass cased ammo.
