I had to replace the barrel of my Colt Trooper 30 years ago, cracked forcing cone. Good luck finding a replacement, if I find one I will let you know c/o this forum.
One thing I like about the Dan Wesson, replacing barrel takes about 2 minutes.
I have been beaned with other shooters brass, never encountered any ricochets or splatter, and I shoot almost exclusively at indoor ranges. I have seen bullet holes in the sides of lanes, unfortunately not all shooters are as skilled ans dafety conscious as member of TFL.
