I never thought much of semi-autos, having grown up with pumps or double-barrels, until my shoulder went bad on me a few years ago. I had pulled something at work the day before, and opening day of pheasant season, it felt pretty weird as I was getting things loaded into the truck. I didn't think much of it, and I got the dogs and headed to my favorite spot. About 15 minutes into the field, the first covey of quail exploded from the grass in front of me. I was carrying the 870 pump my father-in-law gave me for a Christmas present years before, and it was loaded with #8 shot. As I started to pull up on the birds and was picking one out to go for first, I suddenly realized I couldn't find the sights. My arm wasn't working. I couldn't bring the barrel up to shooting position. Not wanting to miss out on what might be my only chance of the day (you don't get many on public lands any more), I managed to swing it up with what leverage I could muster with my trigger hand pulling against my other shoulder and squeezed off a round. I didn't really have a chance to aim, but rather pointed in the general direction of the birds. Nothing. That sucked big time. That was the end of my opening day hunt. I wasn't able to raise my arm even to shoulder height again until after a rotator-cuff surgery. Then, it took a long time before I had full range of motion, but I never did get much strength back. That's when I decided I needed a semi-auto, and something lighter weight, too. I got the 11-87 Premier that is about 4" shorter and considerably lighter. I like it very much and have had no trouble with it after several years of use.
Can you tell me about the fiber-optic sight you have on yours? Did you put it on, or did it come that way? I've wanted to change my "white ball" front sight on both of my shotguns, but haven't found much info on what will work. I think it is threaded but don't know the thread size or anything.
