The Beretta design is GARBAGE and and as such does not warrant itself to slicking up. It has an entirely different internal hand system. The Uberti is exactly like the original Colt albeit small differences, e.g., cylinder is larger, no recoil plate, etc.
Buy the Uberti and have it slicked up. :wink:
P.S.
Beretta bought Uberti circa 2001 or so as Aldo Uberti died in 1999 and his children were not "gun" people per se. Uberti however is a separate entity.
