Tell ya what 44 Man, I love my little Birds head Vaquero to pieces despite it being a reasonally priced and a completely stock sa with a 3"-7/8" bbl.
I think the balance and pointability have a lot to do with this, good shooter too as this bratty little kid brother to my full size Vaquero & SBH begged me to take it deer hunting.
No way, "on the hunting" I told it. To prove my point, I fed it a variety of hand loads with the intent of finding something that it would not like but had no such luck.
It was at this point that I realized that I can shoot a short barrel as well as a long one. This has been arguable on this forum but works for me and I reckon that sight picture is everything.
If you like that short barrel I would say go for it as I dont think you will realize any handicap, I think that it is great just the way it is but perhaps like yourself, the crowning at the muzzle is kind of "different", not really a big factor but the kind of "different" that may need to grow on a person.
