I purchased an 835 as a home protection gun/all around shotgun. 24'' barrel with improved cylinder. I am very interested in purchasing a good light to attach to this shotgun with a momentary switch for home defense. I do not want one that covers the barrel as it will interfer with the rifle sights. I found one on cheaper than dirts website that looks to be decent for under a hundred dollars. Will i have to add a mag tub exstention to put a light on? Thank you for any help or insight.Also i am very happy with my 835 would reccomend it to anyone looking for a pump that will shoot almost anything very accuratley.
