So....already bough the s and w 642 performance center. When dry firing it I can say that the trigger pull is definately smoother and lighter than my ruger sp101 or any of the other j frame revolvers that the shop had in the case and am completely satisfied that the trigger pull is much better than a non performance center revolver. One thing I notice is the trigger return is gritty........and I have to be sure to pull my finger completely off the trigger or it locks up when trying to fire it again. The trigger return on the other j frames I've tried is as much smoother. Anyone else have any opinions on this.....is it a problem or no?
