I have had one for a year and I highly recommend them. I also have a K80, and though it pains me to say it, I shoot the Blaser better. Mine has never had any issues a d I have about 5k through it. Ow.
My experience has been that while I believe the Blaser is every bit a very high quality gun, because they're newer to the shotgun market they don't retain their value like a "B" or "K" gun at this time. I see lots of F16's for sale but they don't seem to move quickly. I got my F16 Sporting used in excellent condition and I got it for $3500.00 and that included the Blaser/Negrini case and 5 Briley extended chokes. I know a guy who upgraded to an F3 and he can't get 4K for his almost new F16.
The triggers and build quality are almost on par with the F3 and the Krieghoff's but the gun is lighter so it feels more lively to me (some people think that's a negative because they feel it recoils more with the reduced weight but if the gun fits properly the recoil is negligible, at least in my experience).
I shot a 100 round course with the f16. Lively is what I like about it. Oddly it handles something like my a400 or at the very least very differently than my current o/u. I had been shooting 1 1/8 Browning 1300fps most of the weekend along with a couple hundred AA supersports. I can say the Blaser had a different recoil than I'm accustomed to but not much different than the f3 that i tried.
Different recoil.... in what way?
I've also tried the F3 Vantage and liked it. On some of the American forums, people are convinced that the F16 is a harder recoiling gun than most others. That's not my experience with either 1oz or 1 1/8oz target loads. As much as I like the F16, if I could only keep one gun, hands down my K20 Sporting. My son likes the F16 so much he claims it's his (my bill of sale says otherwise).
I have dealt with the Gun Dealer on several occasions and they were ways good to deal with. They are always willing to deal on price also. Good luck on your purchase if you find one.
