I have one (28" barrels, 12 gauge) and it's a great gun. My first shotgun. I haven't shot too many rounds with it, but it's been very reliable so far. For me, it points naturally and when I tested the gun at the range (shooting at a 4'x4' target) it shot to where I was looking.
I've seen some older 1100's at the range and they worked reliably and were also beautiful (much nicer wood than mine, and a nice deep blue finish).
I haven't shot mine much since I bought an over/under gun (I'm too lazy to pick up the empty casings that are auto ejected by the 1100, hence the O/U). However, the 1100 points more naturally for me than other shotguns that i've tried.
