I've been reading a bit about the properties of aluminum, and though I don't have the scientific wherewithal to assess what I've found, it seems like aluminum is not ideal for pistols, as it can endure far less stress than steel. Am I mistaken that an alloy PPK (specifically a 1966 .22 PPK-L) would have a much shorter life than a regular steel one? I'd like to avoid buying a safe queen, and since I have no idea how many rounds have been put through one I have my eye on, I'd appreciate anyone's insight.
