They are a great gun. Harlan Campbell shoots one. I've seen a bunch out at the range. If you shot one an liked it, you won't go wrong to buy one.
If you want to get some different perspectives see if you can handle a Blaser F3, a Perazzi MX-15, a Beretta DT10 and a Caesar Guerini Trap. I would put those guns all in the same vein. There are some here that will take exception to my mentioning the Caesar Guerini in the same sentence with the others, but oh well, I can take it.
All those guns are the same and yet each has its points. I usually find that most will prefer one over the other. If possible, handle them all then decide. If that's not possible, buying the K-80 isn't a bad choice.
