I'd have to confess to be a besmircher. I like the unlugged looks better. The lay nicely when shooting, but I dont care for carrying them, or the looks.
Had a 5" lugged barrel that I installed on my 6" 29. Didn't last long, just didnt care for the looks. Sold the barrel on the smith forum. Have a 6 1/2" lugged 629 Classic barrel I'd gladly swap for a mountain gun barrel.
"Far better it is to dare mighty things, to win glorious triumphs even though checkered by failure, than to rank with those poor spirits who neither enjoy nor suffer much because they live in the gray twilight that knows neither victory nor defeat." -Theodore Roosevelt-
