I can't find a lot of info on the pros and cons of each (Remington 870 pump thumbhole and the Mossberg 835 ulti-mag thumbhole)...so I thought I would ask if anyone had used these or tried them out before and what they liked / dis-liked about each. I am not really interested in the automatic version...I want the pump. I plan on getting on of these for my bday, which is comming up in a little while....
