Beretta Pico with pinky extension partially lopped off. I have medium sized hands and can only get 1.5 finger grip on the gun w/o an extension. I'd say that someone with large mitts would only get a 1 finger grip w/o.
Pros - reliable, DAO w/2nd strike, thin, & nonexistent recoil due to the low bore axis.
Con - 1 finger grip for large hands due to the low bore axis, & it's a 380.
