If you want a Pinto, then make a Pinto
It is your gun, enjoy it the way you want to
Personally, I would not have bought a Model 49, I am not a fan of bodyguards even though my Avatar is a Bodyguard (the only one I own)
I do have plenty of Model 36s and would not hesitate to make one of them into a pinto if a clean cylinder and barrels were to drop into my lap. I would probably use this square butt
Now if a model 40 were to pop up, that would be my donor to make a carry pinto
