Hmmm .... the .44 Spec. also has about 150 to 200 foot/pounds LESS energy thant the .357, according to my Sierra manual. Worse yet, some of the .44 spec. snubby velocities I've seen in gun reviews are so low (around 700 fps or less) as to yield foot/pounds in the 200's. That's .38 spec. territory, not too impressive.
A 9mm carries about 360 f/p's, and no one is going around saying it's a dragon slayer. I think 40 S&W and 357 mag., which seem to be the best manstoppers out there, yield from around 450 - 600 f/p/e.
Not saying there's anything wrong the .44 spec. choice, but having recently decided NOT to go that route, I thought I would share my thinking on it. IMHO, picking a .44 Spec. over a .357 is like re-inventing the wheel in a bigger, heavier, less-effective package. Big bore is great, but if hamstrung by too low a velocity, it looses its punch. I decided that you needed something more like a .41 magnum to get markedly better results than a .357 would give. There is a reason why .44 spec. isn't more popular.
In my experience, the muzzle flip and noise are every bit as bad as a .357 snubby. But to me, all short-barrelled guns are too loud.
