the stress of (A FUCKING EXPLOSION) that happens when you fire a round tends to cause metal frames to crack but plastic frames to bend and flex when they're the same thickness. Being "stronger" than plastic is a bad thing in this case as you would need to make it "tougher" than plastic instead.
beretta makes a pocket 32acp pistol out of actual forged metal that still cracks even though its thicker than a fucking fist.
but you know that you're just being a retard on the internet
