Congrats! I love my Dan Wesson CCO. You're right about the tight fit, I had the same experience. Mine loosened up a bit after about 200 rounds. Now I can get the barrel bushing off without the wrench, but still very tight. Enjoy your new gun! Looking forward to an update after you've taken it to the range.
