I've never shot a PX4 Storm, but given what I know about Glocks, I'm wondering what the trigger pull on the PX4 Storm is like. I've gotta tell ya, when I've shot many different kinds of guns in my lifetime, from ultra cheap to ultra expensive, and everything else in between, and out of all of them, the Glock has the most unusual trigger pull of all, and I'm still trying to get used to it. I know that Beretta has a reputation for making good guns, and if given a choice between it and the Glock, at least based on what I know about Glocks, I would probably choose the Beretta (although you can never go wrong with the Glock, as long as you're willing to take the time to adjust to that weird trigger pull).
