Greetings My Good Quicks Draw
well, it all depends upon where you are going with it and what *you* want to do....
if one wishes to remain correct to the historical period, one would probably want the bevel.
if one wishes to stay ":old timey" but has small paws, would the square bottom might be more comfortable?
on the other hand if one dances to their own drum...
I myself prefer the pinky groove as demonstrated by our own Tinker Pierce here:
I really like birdsheads and pinky grooves!
Bear in mind that I do not think it will fly with the SASS head honchos ( re rulebook) but I don't shoot SASS for score,
and where I shoot they don't care what you bring as long as it fits the loose definition of a SA cowboy gun lol....
this probably won't help, but I hope it is at least entertaining
yhs
