Mossberg 935 freezing up

I searched and didn't really find an answer to my problem. I have a mossberg 935 and it cycles fine when it's inside my house or when it's when it's warm outside, but when it gets cold it cycles really slow and sometimes gets stuck. It usually will eventually close the chamber but it takes it a few second. When I watch the action close, where the action goes slow, there is some lighter color likes it been rubbing. It's almost like once it gets cold the action shrinks just enough to make everything a little too tight. Any suggestions on how to fix this?

I doubt you're getting any shrinkage, but only you can attest to that. lol

I'd break it all the way down, and spray and scrub it all the way clean. A lot of times when a gun acts more sluggish in the cold it's because there's too much oil and residue on it. Happens a lot to people who just continually spray/squirt more oil on their guns throughout the year instead of really cleaning them. Oil gets gummy when it's real cold and that's not good for moving parts. I have a couple semi-autos that I run nearly dry during the real cold months. Just the tiniest touch of oil on everything except the trigger assembly. Could be something else, but I'd try that first.
