I grew up on pumps too and have to say that I would have no problem with bringing a semi-auto to an intense fight. I've been very impressed with my mossy 930spx in terms of reliability. It feeds every brand shell I've tried to put through it flawlessly and allows me to re-acquire the target quickly, putting a whole lot of lead downfield in a hurry.
I'm not saying that it is any better or worse than the 1100 series, just that I think there are a number of good ones out there and share your enthusiasm for today's semi's.
You say you support our troops. How about actually doing something? Your blood or platelets can save a life Armed Services Blood Program.
