I bought a 935 two seasons ago and have had mixed results with it. Right afterI boughtI gave it a quickcleaning and took it out shoot a few rounds of trap with it then took it duck hunting the next morning. The first morning it was COLD and it froze up on me within a half hour. I figured there was some sort of packing grease or something i didnt get out of it and took it home and gave it the full rub down. Well the next weekend i go out and the same thing happened again soI did my research and read that sometimes the spring in the stock will get gunked up on a new 935. SoI took that apart and cleaned it up and it would cycle fine until i went out hunting about a month later and it froze up again. After this I took it to a buddy who is a gun genious and had him take everything apart and clean everything and put it together for me. Well this season i took it out for another try and havent had a problem with it. So to make a long story short after i got it running fineI loved it but it was kinda frustrating at first.
