Help with M&P mag release rusting
I'm having a problem with my M&P mag release rusting from sweat. I carried a H&K P2000sk for several years and all I did after a sweaty day was spray rem oil on a rag and wipe the gun down. Never has a rust problem ever. That's what I have been doing with the M&P and the other day I went to release the magazine and the release would not push in. It has rusted stuck.
Do I have any other options other than stripping the gun down and oiling everything every night? Maybe this is common practice and I just was lucky not needing to do it with the H&K?
