I received the frame back and while it is not the same color as when I bought it, it is a great factory finish. My problem is that when I shoot it, the hammer doesn't stay back for a single action shot. If I manually rack the slide, it stays back. I've tried different ammo and get the same results. I never had this issue before it went back. What could be causing this? I will call beretta tomorrow, but I was hoping there may be something I could do at home.
