battue -
I would never ask one to lay aside their personal observations and experiences. It looks like we've seen the opposite sides of the spectrum.
I have seen 1100 mag tubes that have fallen out, but these were on guns that had absorbed 20k rounds per year for more than a decade; they were just plain worn out.
I don't have an 1100 anymore; gave it to my son who is currently shooting the snot out of his 20 year old 1100. This was an 1100 I picked up used after the previous owner who shot it regularly for trap said he thought it was worn out. It had a worn out magazine spring; back in the game.
My only Remington semi-auto these days is a 20 bore Model 11, which is about 70 years old and perfectly reliable (and just plain fun to shoot).
Honestly, if I were shopping for a new semi-auto, I wouldn't be looking at a new 1100 (perhaps a used one if price was a concern). The Beretta's and Benelli's are the new generation of autos and they're much better.
