This. I would do this after you clean up your gun a bit after playing, so when it's stored somewhere for a while the orings don't dry out.
I would do a full disassembly/cleaning/lube once or twice a year. It's easy after you've done it a couple times. Just follow a video on youtube and remember where the parts go.
