I want a tough built to last .22 lr revolver. I want to get one to practice with as a cheap plinker and one to carry in my backpack. Figure it might come in handy for emergency food from small game. I am looking at the 317 aluminum and the 63 stainless steel.

There is an obvious weight difference. How much tougher, longer lasting, more durable would the stainless be over the aluminum? Will the aluminum hold up to as much heavy use?
