Let`s walk through my choice, the 4" s&w model 24 - 3 in .44 special.
First the weight. It weighs about the same or even less than my s&w 66-3 or 4" colt python. They are in .357. Also less than my colt saa,s in any caliber.
The .44 special will do 95 % of what we really buy the .44 mag for. Except for a mag in a mountain gun the model 24 is less weight and easier to pack than a heavy barreled model 29.
The 24 has adjustable sights, my colt saa`s doesnt. I have a flat top .44 special ruger single action with micro adjustable sights that is nice, but even that one is noticeably heavier to pack than my colt single actions.
The 44 special is more pleasant to shoot than a .357, more knock down, less sharper kick and less sharp muzzel blast. The .45 colt is about the same as .44 special, yet the .45 colt in colt saa`s, colt STILL hasnt got it right in the size of their chambers. Unbeliveable! I also own a s&w 25-5 4" in .45 colt that is nice, but still feels "clubby" in comparasion to the 24 because of the heavy straight barrel.
I sometimes carry a old m&p 4" 38 special in the boonies as it is light and I aint scuffing up my more exspendsive classic`s and its almost as good as it gets too.
So there it is. The 24-3 4". Now I dont own, but admit that a s&w mountain gun with the pencil barrel should be as good of a choice in any caliber, also stainless would be more practible, but I get along just fine with what I have.
By the way, I like the compact smaller magna style standard service grips on my 24. The oversize targets changes a lot of my argument!
