Picked up my used gunbroker K40 today and went straight to the range for some shooting. I looked over the gun then shot one mag to make sure everything was working correctly. All went well so I then field stripped it to inspect things (very clean) and went ahead and cleaned and lubed everything anyway. Then proceeded to shoot 100 ball ammo and about 30 hollowpoints and everything fed and ejected perfectly. Brought it home and field stripped again. The barrel and chamber had some discoloration so I went and head and polished it down some, not to a mirror finish but a clean uniform sheen. Well here are a few pics I snapped today with my cell phone.


Here is how the barrel was before polishing (picture actually makes it look a little worse than it was).

After polish.
