Mine is a .357 Mag 686+ but, it still has all the standard Mtn Gun features. Rounded grip, 4" tapered barrel, half-length shroud, etc.
My L-frame, 7-shot Mtn Gun weighs exactly the same as a K-frame, 6-shot S&W model 19. That makes it a total joy to carry and it can handle a steady run of full-house magnums without any problems - something the 19 is known to have problems with.
Your .44 Mag is essentially the same thing, just in a more powerful package.
