The .41 is usually a really accurate gun. The dimensions of the case, throat, neck, and barrel were always set in stone, unlike the old .45s which might have a .454 bore, or some of the ".44s" which might have bullets that are .427" or maybe .429 or 430" or whathaveyou, depending on who made it.
Since everyone was making them to the same specs, it's easier to get an accurate .41 than the others. I do not dislike the others, but it seems to me that the .41s are easier to get shooting really well.
This.
41 mags generally have throats from .411 to .412, almost universally.
32s, 38s, 44s and 45s dont have that.
