I've read posts from people on the difficulty of changing barrels in the field or at the range. Some time back I bought a cheap tool at an Ace Hardware store that totally revolutionized my Encore experiance. It was a brass machinist's hammer that included several screw drivers within the handle. I believe I paid about $6 for it. This tool contained every size and shape screw driver I need for take down of all my Encore barrels as well as a perfect diameter, non-marring shank for pushing out the hinge pin. If you can find this tool at an Ace Hardware store, or any other store I highly recommend it for all Encore owners.
