Was at the range this morning with my typically carried 642-1. I must say, this is one accurate little firearm. With nyclad 125's (standard pressure) it shoots true to point of aim out to 10 yards...and accurate enough out to 15 yards. I can't think of a more perfect, always with me firearm.
I also took my LCP, never had a failure of any type with it, and it easily digested a box of Hornady Critical Defense. Its a nice gun, reasonably accurate for its intended purpose, and I like it a lot and carry it on occasion, but it wont ever replace my 642.
