I wanted to get a shotgun that I didn't have to modify, and had sights that I were used to (i.e. M-16 style), and saw this 500SPX. With the telescopic stock and pistol grip, I was sold. This is pretty close to what I was used to shooting in the military, with the sights, grip, and butt stock, so it felt more comfortable and familiar the first time I took it to the range. 'Course the recoil from 00 buckshot is a LOT more than .223 rounds, lol! But the rear sight only needed a slight adjustment from the factory, then it was pretty much zeroed. This is a nice looking tactical shotgun, and will make a great addition to my home defense collection.
