Ya know guys it aint rocket surgery. If you put lotsa rounds thru your shooter you really do owe it to yourself to take it apart and clean it. In two extreme cases I own a couple of M-60s that would come to a halt completely if they weren't disassembled and cleaned after firing.
I bought this guy and when I pulled the side plate off I had to chip the dried up grease and oil out of the action. It curently has the best double action that I have ever seen on a Colt.
