I have a .40 S&W for home defense and when i feel like im goin somewhere i wmight need it and ive never had a major problem like that. It wont shoot Fiocchi ammo well. I get 3 out of 50 that wont go off. But all the other brands i shoot for practise work well. I use Remington Golden Sabers for defense rounds. They were reccomended by a few cops and others i know that need good defensive rounds. I have them in three of my pistols now and im waiting to get some more for another one.
