I had a Moss. 835 when it was new out of the box I had to work on it, it would not let a new shell go up into the chamber and yes mine jamed 3.5 shell. My best friends safety broke on his took 4-5 months for the company to fix it. Come to think of it I had a lot of problem with choke also I went throught 4-5 choke and I still could get it to shoot the way I wanted it to. I have a rem. 870 and it has smooth action and shoots great. One thing I like about the Moss. was the ported barrel which my Rem doesn't have. I could tell alot difference in the recoil.
