For me the tour was a bucket list item. I too dabble at building some. My favorite to this day is a old colt trooper 357 I was competing with (think early 80s) I bought a Barrel blank and milled flat sides vent rib and did the threads etc. it was stretching my ability. Thing weighed a ton when finished. But I could get on target instantly for 2nd shot result of the barrel weight. The technology today makes those kind of solutions comical now. But back then it was innovative, but so were bell bottoms!
