We have OC here in Indiana as well. I will set aside the politics of that issue and just say that I do OC on occasion when I think I can get away with it without being hassled.
I also have a S&W 629 revolver, which is a .44mag. I OC it on occasion - in fact, I OC'ed this gun over the weekend on a hog hunt, and on the road to and from.
My gun has a 6 inch barrel. It would be impossible to conceal on person, but it carries very well in my cheapie

D) nylon holster - the key is a good belt. I use a Galco gun belt which is wide and stiff. It was comfortable to carry when sitting in the car, when pumping gas, when eating out, and of course hiking up ridge lines in the field. It served its purpose very well. Its also comforting to have that extra power when you hear a boar grunting in the distance.
As for power/recoil, I have a bit of advice born of experience. Buy and use the cheap ammo:
* Budget brand ammo like Blazer or American Eagle keep recoil down, because they are light loads (
only 650 ft-lbs or so

).
* Even "light" .44 mag still has PLENTY of power for personal protection, and hunting any animal under 500lbs.
* The bullets I have recovered from such ammo still retains a respectable amount of weight and gives expansion (Recovered Blazer HP expanded to over 1/2 inch, and retained about 80% of weight.
* Such performance is sufficient for quick kills on virtually all medium game.
In my experience, I wouldn't go any 'higher shelf' than Fiocchi - they can sometimes be found around $35 for 50, and they load Hornady XTPs. Even so the Blazer, American Eagle, and Sellier & Bellot budget offerings are virtually always available usually a hair cheaper, and they perform quite adequately.
Unless you need to hunt Elephants or Kodiak bear, the boutique ammo like Double Tap, or Buffalo Bore are completely needless, and cost WAY too much for what they are.
A 4" barrel gun would probably carry nicer, especially sitting in a car or in a blind - especially with a nice holster. Even so, a 6" gun is in no way a problem.
