I am interested in two different models for my first gun. 4013tsw and 410s. Local shop doesnt have 4013tsw in stock, so can't compare side by side. 410 fits hand very well. Is the 4013's grip size closer to a 410 or a chief special. Any does anyone have any useful words of caution on either models? Also, the 410 is available with a crimson trace grip for a little extra$. Are they a waste of money? Thankyou, Anthony
