I was at a tactical match this morning. As I was waiting my turn, I was talking to someone and asked him what he used for the carbine. He said he HAD a Beretta Storm. I asked "what do you mean HAD?" He said that during a match he picked up some 9mm ammo, used it in his brand new Storm and the gun went kaboom. Totally destroyed the frame and gave him a big owie on his hand.
That was a $900 lesson to save 20 cents.
