I was in Miami most of last week, and while browsing a local dealer's stock, I found this NIB little belly gun.
It has a lock, and according to the shop guy, no one wants the lock. Everyone wants the model without it. I would prefer no lock myself, on principle if nothing else.
HOWEVER, he was willing to knock $80 off the price of this one to move it, so I brought it home.

Model 442, light weight, hammerless (DAO) and +P rated. I love it.
