After a match Ill field strip my gun, spray down everything with rem oil, soaking the sear, trigger, mag release areas.. then bore snake the barrel, brush the feed ramp, extractor, and inside grip clean, wipe down everything, lube rails and lugs with lucas lube.. (moving to gun butter soon)
mags get broken down, brushed in and out, then wiped down in and out w/ a silicon cloth.
I may go 2-3 matches at times before field stripping my gun but I wont run a dirty mag.
firing pin channel gets a pipe cleaner every 6-10 matches.
