About a month ago I picked up an 870 and left the 11-87 at home. It wasn't the perfect marriage I'd hoped for. Started out short shucking a few shells, forgot to pump a few times in between birds, and couldn't hit as consistent. I couldn't see myself hitting doubles with this gun so I even took hje 11-87 back out for some good old times. Today it was -15f and I could tell by the frost that my gas gun was going to have fits, so I threw the improved cylinder in the 870 and headed out hoping for the best. Two others had autos, a browning silver and some cz auto. The cz never did fire a round, apparently the factory oil froze, and the Browning turned into a clumsy single shot after about 5rnds. The 870 had a one shot - two birds, followed by a triple on mallards! It worked flawless and ended up getting the other guys limits. I'd planned on saving up for a super black eagle, but I'm kind of liking this pump gun reliability.
