not to turn this into a cleaning thread,,
but cleaning is simple as can be,,
take the lock out, clean it with a tooth brush and warm water,,
put a tooth pick in the touch hole, pour some warm water down the barrel..let set 5 minutes, or so..
dump water out of barrel,,i run 3 to 5 clean patches down the barrel,,until they come out clean,,
wipe lock dry and give a few drops oil, run the same patch down the barrel, put lock back on and your done,,
takes 10 mintes,,maybe..
