I like my 629MG with it's proper-looking (... to me) partial lug under a tapered tube. The 4" is a valuable length, able to be pointed quickly and be accurate to quite a distance. An upgrade would be to the 6" half lug, a version definitely on my 'short list'. Of course, it would be better for precision distance shooting due to the longer sight axis. Still, if I could have but one .44 Magnum, it'd be that 4" 629MG - and a set of the X-frame/.500 Magnum Hogue grips - they help the recoil tremendously.
Now, for a handheld rifle, go with a Super Redhawk with it's included rings for your handgun scope. Not a multi-use firearm, but very good for it's designed role.
