The 642 is a good gun, but I'm getting back into a Colt. The trigger on the little thing is just too darn heavy.
For carry it's superb. 5 rounds of .38 + P SB load Gold Dots in a pocket is very nice.
It's fun to shoot because it's a challenge. It sucks to shoot because it makes you wish for a bigger gun.
I shot mine a lot and no problems, no malfunctions, nothing like that, but my groups at 21 feet were like 5". Now some people are real good shots with these things but not me.
I think getting one, finding someone who will slick it up for you, and getting the right grips will yield a very nice little gun. Personally I think I'm just going to switch back to a Colt and live with babying the gun a little bit.
