I just decided with you and I plunked down some hard earned bucks for my S&W M29 'Trail Boss'. It has a 3 1/2" ported barrel. Barks like a real big dog, and kicks like a much bigger mule. Yes, I carry it, but only with my 44 spec load. Heavy cast loads are not fun, Heavier Jacketed at not much fun either. (let me clarify fun) They are a hoot, but the gun kicks and hurts twice as much as my 375JDJ with an arrestro brake. Muzzle flash at dusk is a sight to behold. I think if I was gonna shoot one regularly, I'd opt for a Taurus Raging Bull with the multi-ports. It's a little heavier and is a little more pleasant to shoot. Plus, it's about 1/2 as much as a S&W. Mine is limited edition though. You did say carry all the time. That's why I got my S&W. I vote for the Ragin Bull 4" as the one to fill your bill. Also, you didn't state, side holster, concealed, shoulder rig. I persoanlly think all 44's are too heavy to carry all the time, inless you pick a Ruger Blackhawk .44. That would be no worse than a .45 Colt or even an ACP Steel framed gun. Carrying one all day will cause a limp!
Good luck in your choice. They're all fun!
