Funny you should ask. I bought one in June, cleaned it when I got it home. Shot a bunch of clays this summer, a few boxes of junky walmart loads during dove season (cleaned it after dove season), and this morning it went on it's second duck hunt without a jam, misfire, zero problems. This morning was cold here in Idaho too. Snow and rain this morning with ice frozen to the barrel and other parts of the gun, boom boom boom every time. I dig this gun and I would recommend it to anyone.
