First outing with the 642UC. Ammo is Black Hills 148-gr. WC. Distances 5,7,10 yards. Various time pars, some support-hand shooting.
Bottom line? It shoots very much like my 640 Pro, but it's seven ounces or so lighter. The sights seem quicker to pick up than my 640.
The grips felt great to me, but I also have big hands and N-Frame guns feel fine. Folks with little hands might want something else (another great advantage of revolvers). My hands did not hurt like they do at the end of 40-50 rounds through my other 642 with minimalist grips.
It carries just fine in my old DeSantis pocket holsters, but wants to drag my Wilderness Tactical DB Force Option out of my pocket.
Overall, I'd say "mission accomplished" to the brain trust that put it together and I'm looking forward to running more ammo through it and taking it to a class or two.
