Goat,
I have had mine for about 6 months now and really enjoy it. It has had about 3500 plus rounds through it digesting all types of ammo without a problem. The felt recoil is less then with a full metal pistol and the recoil recovery time is almost non-existant. It will group better than advertised. The finish has started to show wear but I always use a Kydex holster so wear marks were to be expected.
When Wilson's starts to ship the compact version of the KZ this summer I will certainly pick one of those up too. And yes the KZ is in great demand and the price you quoted is under list so I would grab it while I could.
Good shooting,
Dean
