Amazing shotgun

This was my first of a few guns I have bought and it is still such a fun gun to shoot. I got the 590 with a heat shield. I am glad I got the shield because the barrel does get quite hot after putting 20 rounds through it quickly.

590A1 TALO US Service Model 9 round

Very reliable and extremely durable model used by our military and police. Holds 9 - 2 3/4" or 8 - 3" rounds. Loading is very easy and it gobbles up ammo like a hungry hog. 20" barrel with small bead sight is accurate. Recoil is manageable.
