I have several of both sp and mag in 44
The problem with a 44 mag with short barrel is the muzzle flip and the ability to see after shooting one at night.
You havent said if its for carry or just shooting.
If you want somthing in 44 to carry. Look at a Charter arms 44 bulldog. I have one with over 400 rounds and its been reliable, I will agree that a gun like the bulldog has a short life span if its shot a lot, but its hard to get somthing the size and weight unless your willing to spend the ammount for a smith.
I had one of the smith titanium 44 sp (forget the model number) double action only, with the covered hammer.
I was going to retire the charter and carry just it, but The trigger pull level was so high that (several people shot it, some much better than I) no one could hit the right side of a barn with it. Had the hammer been exposed I might have thought differently (plus the darn thing was so uggly I was embarrased to carry it).
Smith has an other 44 sp called the Thunder ranch which looks good on papper but the price is crazzy.
I have a 629 with a short barrel, non fluted cylinder and love the gun, but to carry you need a gravity cancling device and that invisable sheet that Harry Potter has.
