I own a remington 870 18" synthetic shotgun for home defense. I am in the process of upgrading my case for a higher quality hard case to store in my home. I would like to have a combination lock built in, as well as the holes for a pad lock. I want to prevent my child from gaining access, but I would also like something I can open fairly quickly in case I need to protect my family. Do any of you know of any cases that may be good?
