OK, first we have to get clearity on one thing. I cringe when ever I see some reference to having "problems" with a magnum 1100 not cycling light loads.
That's because they weren't designed to! The 1100 was never designed to be able to interchange 2.75 and 3 inch loads without changing barrels. It's not a gun flaw, it's an owner flaw.
Now with that out of the way, yes I've owned an 1100. The nifty special field model with the straight English stock. Nice gun, fast handling. Far too much was made about the so-called "o-ring problem". Replace it every 3 years and you'd never have a problem. Total cost, less than $5.
It's a fine design overall and the 1100 will be a solid choice for years and years to come.
I sold mine off though, because IMO times have moved on in some regards. The 1100 was just too darn heavy for me compared to the modern lightweights like the Beretta and Benelli. Once I started carrying these guns, the 1100's extra pound+ felt like an extra ton.
