harmonic really put it in a nutshell.
For a silhouette/range gun, the SRH is great. But for a woods/carry .44, it's too big and heavy. Get a pre-lock S&W 629, Mountain Gun or, heavier but still doable, a Ruger (
non-Super) Redhawk 4":

There is also the funky "sawed-off" version of the Super Redhawk, the Alaskan, whose 2.5" barrel makes it comparable to a S&W 629 in weight. I must confess I want one:

All these Ruger double action .44 Magnums are basically nuke-proof. You can shoot all the full-power, heavy-bullet 300 gr Magnums you can tolerate.
The S&W .44 Mags are tough guns too, especially those made in the last 20 years, but by most accounts are not
quite as resistant to very hard use. The Smiths tend to have smoother actions than the Rugers and slightly superior fit and finish.
Personally, I prefer to do my .44 shooting with medium loads like factory 240 gr Magnums and heavy .44 Specials. The S&Ws digest these with ease. I found the svelter S&W 629 was a more practical gun than the (mostly) heavy Rugers. Backpacking; car carry & nightstand (w/ .44 Specials); range shooting. Very versatile.
