I have two. One Model 53 K 4740xx 6 inch barrel has target grips with black washers and a diamond, regular sights, trigger and hammer my other is a 53-2 4k490xx 6 inch barrel target grips silver washer, no diamond, target trigger, hammer and target sights (white outline red front) why the marked difference between the two? I always thought Model 53 came with target gear. Which one is less common?
