bountyh,
Let me guess....
It was an ELITE II in 9mm!
No, I'm not psychic. Mine did the same thing.
Contacted Beretta and got a lot of BS about trigger control and theory of using open sights.
I might have paid a little more attention if this weren't the 4rth Beretta I have owned and the first one with this problem.
Anyway, no offers on their part to fix the problem.
I'm eventually going to bite the bullet and have adjustable sights put on mine too...
