The top one is the P.C. 629- the grips look more comfortable if a little cheaper than those on the 21, and I prefer its matte S.S. over the nickel finish, but I do like the classic's 4" barrel vs. 3", its tall F.S. They are 38 & 37 oz respectively, and the P.C. model is about $100 more expensive. It's a tossup to me. Depending on how much P.c. actually means a nicer revolver vs. marketing & a nice Al case would tip the scales, so I'm looking for F.B. in that regard.
