I would prefer the 44 but would take the 45 because it's easier and cheaper to find ammo for it. Reloading is a plus and if you do the 44 would be a great choice. 5 1/2" is a great barrel length for what I use my guns for but your needs could be different. Kind of like underwear, it's a personal choice.
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.
