Firstly, Clif, I was a police department Range Master and certified instructor for many years in most all weapons short of RPGs although I fired one or two of those so I have shot them all. If you like the .44 mag, go for it. I would not recommend it then and I don't now but to each his own. Most can get 14 on target from a .40 or 9mm easier than trying to keep that big 44 on target.
Jim we have open carry here too but I prefer not walking around town looking like the old West. It scares fewer moms and kids and gets fewer bad looks from business owners.
44 is a terrible self defense weapon - large, hard to conceal, heavy, difficult to hold on target because of huge recoil - not much good about it about it unless you like to go to the range and shoot metal silhouettes
a 357 is my favorite range gun for killing paper - love the balance of my Ruger
a 9 is a light, fast round with limited knock down capability - if it's your choice, pull the trigger a lot if you need to use it
40 or 45 are the ideal weapons for SD - powerful, fast, easy to conceal, great knock down power, easy to reload, reliable. My personal preference is a 45 because I used to compete with one and it's what I carried in the military (before they went to 40's). If you know how to reload quickly, number of rounds in the mag is a non-issue unless you are in a "Hollywood" gunfight.
A small 38 wheel gun without a hammer is an ideal pocket gun
I also have a 5 shot 22 revolver that can be concealed almost anywhere - a great little backup. (the tiny derringer type like the NAA)
But hey, that's just my opinion
