I've been using one as my primary trap/skeet/sporting clays guns for the past year or two and overall it's been excellent.
100% reliability through several thousand rounds, shoulders and points very nicely (for me anyway). It's light in weight and very light in recoil. The light contour barrel swings quick and the rib is very effective at dispersing heat without interfering with the sight picture. No heat mirage along the rib is something to appreciate during a summertime round of five stand.
From the factory the fusions come with an interchangeable fiber optic sight (and bunch of fiber inserts) as well as five chokes. I found the whole package to be quite good value.
Tear down and cleaning is quick and easy and reliability wont be affected if you let that go for a while. I honestly don't have any detracting points to raise, for me it's been a very good performer.
Hope that helps in your decision.
