I was wondering if there were either Smith or aftermarket sights available for the gen 3 auto's. I was looking at one for my son and want to know if it's possible to get taller or shorter front sights in the even the pistol is hitting high or low. What about replacing the rear sight with an adjustable sight (windage and elevation). Also, has anyone here installed a set of the Hogue wood grips on one. How well do they fit and how do you like 'em. they're not cheap but not too badly priced either. For the price I can get the gun at I thought it migh be nice to include a good looking set of wood grips. Thanks
