Beretta generally enjoys a very good reputation for quality, but this particular model has been known to be problematic for some. Cracked frames are more common than I would have thought, and this is sometimes attributed to the material (aluminum) and size of the frame, which doesn't differ much (if at all) from the frames of Beretta pistols chambered for the much less powerful 22 LR and 25 ACP cartridges.
My gun's frame is still intact, but it's easy to see where the weakness lies. The cracked frames which I've seen photos and videos of have failed on the right side of the frame, below the chamber area of the barrel. The frame is inherently weak at that point, because of the large slot cut in that side to allow engagement between the trigger and the trigger bar (which rides along the outside of the frame, on the right side).
I have shot a few hundred rounds through this gun - and I bought it second-hand, so I have no way of knowing just how many rounds have been through it, but as I said, its frame is doing fine.
In the photo, you can see the left side of the pistol. The magazine release is that little button towards the bottom rear of the grip. The safety (disengaged in the photo) is at the top rear of the frame. Just forward of the front top corner of the grip panel is the barrel release (pivot the knurled portion forward to allow the barrel to hinge upward).
Stamped on the left side of the steel slide is a PB logo inside of an oval(Pietro Beretta), and "3032 TOMCAT-32 AUTO MADE IN USA." Stamped on the frame below that is the serial number (which has been mostly removed from this photo).
