I've had an 1100 for about 17 years now, and it still remains the best shotgun in the cabinet. A couple of years ago I joined a trap shooting league. I ended up shooting the remington because it worked the best for that. One guy on our team does this religiously, so had a custom shotgun made to fit him specifically. This was a $10,000 single shot!!! One week he was having a little bit of a bad day, and was my best day ever, I shot a 48 out of 50, and he shot a 47. So my $300, crappy, beat up 1100 out shot him!
Both the 1100 and the 1187 are good guns, but you must clean them well and make sure not to over lubricate them, just enough oil to coat the surface. I now only use my 1100 for deer hunting, and still no problems. My buddy does have the 3 1/2" version, and it works fine if he uses heavy loads, no field loads for that gun.
