No BS take for home defense with a true 6 shot, American made .44 Spl you can always shoot mild .44 Spl loads in the magnum guns.
Ruger Redhawk 44M RH 44M Tank built DA, eats anything, smooth enough. Big and heavy overkill for house use.
Ruger Super Redhawk Alaskan 44M Short 2.5" barrel, super strong, but brutal recoil even with .44 Spl and awkward for fast follow ups indoors. More bear in the yard than bedroom gun.
S&W 629 Mountain Gun 44 Mag 4" tapered barrel, 39 oz, great balance, excellent trigger, and shoots .44 Spl very softly. Classic, accurate, and controllable.
S&W Night Guard 44 Spl 396 Lightweight scandium 23-24 oz, compact, but only 5 shots and snappier. Not 6 shot.
My pick: S&W 629 Mountain Gun in .44 Mag. Load it with good .44 Special defensive ammo like 200-240gr JHP or hardcast and you get soft recoil, six rounds, real stopping power, and a gun that points naturally for quick home defense shots. It's the best all around compromise not too big, not too light, made in America, and actually fun to shoot.
If you want something even more dedicated to soft shooting .44 Spl with six rounds, a used S&W Model 624 or similar N frame .44 Spl would be ideal, but among your current options, the Mountain Gun wins for real life home use. Rent one if you can you'll feel the difference immediately.
