I have the 11-87 and have had no problems with it. There have been many problems reported with QC of 11-87's in the past, but I have never encountered one myself. I also have 3 1100's in the small gauges that I shoot more lately. I have only put maybe 1 box of steel shot through the 11-87 in 3" mags, but probably 35,000 rounds of target loads. These have been mostly for targets and quite a few for hunting. 3" loads are not really necessary when hunting if you are reasonable in the distances you shoot.
Now that said, the 11-87 did not last on skeet fields because they weren't considered as durable as 1100's. All guys did with their 1100 was swap a new O-ring out about every 5000 shots just for insurance and kept on shooting them. I prefer the looks and style of an 1100 over an 11-87, but there is not a big difference between them.
