picked up a new 642 today at the tulsa gun show.I guess it would be the base model for this model,other than grips to soften the recoil and get better grip(does this have a bad recoil?) is there other things you can do to this gun to make it better or more user friendly? this is going to be my main conceal gun and I like the trigger pull. mag-na-port?cost? any idea's? I really like this gun so far and can't wait to shoot it. I did alot of research and had narrowed it down to the 642 and the lcr in my price range. i think i made the right choice. thanks in advance.....
