Cold weather affects everything that needs to move. Oil is good, grease is bad in cold weather.

Tetra Gun grease will lock a 1911 slide up in cold weather. Ditch the grease and use a light oil in really cold weather.

Maybe not use grease at all. M1 carbines came with a built in oiler tube in the stock.

Lots of lubes on the market but oil always works if you use it on moving parts.
