I needed a hole in my vehicle (non-Beretta) and I used an electricians knock-out punch to put a hole through the firewall. You might try it.

As for beretta technical stuff, post in the corsica forum on here... Berettas and Corsicas are the same thing with a little bit different sheet metal and a different amount of doors.
