I got an 835 long ago when they first came out. I shot it for years and killed lots of turkeys, some coyotes, quail, ducks etc. with it. It is not the smoothest pump, but it always worked for me. I had to send it back to Mossberg after many years to have some work done on it, as the bolt was sticking when cycled to the rear. They replaced the bolt with a new one at no charge and I had the gun back within 10 days total time. Mine does not have a ported barrel like the new ones. The porting should help with the recoil, but do not buy this gun if you are recoil sensitive.
I have since also bought a 935 and I like it better than I ever did my 835.
These are both great guns for a fair price and unbeatable factory service.
