Have both, like both, shoot both equally well but I carry the 41 because it is of the 4" persuasion and my 44 is 7 1/2" Hogs and deer will not notice the difference.
When it comes to finding ammo it is true I can almost always find 44 mag easier then 41 mag and 44 spcl is the hardest of all so I find myself buying them whenever I see a box just to make sure I have some on hand. I do recommend Hogue or Pachmayr grips for it if you get the 4" version because it will set you up straight and let you know you are shooting a big dog.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
