From every thing I have read they are good. Haven't seen one for sale at any of the shows, sites or stores I haunt. I would like to try the gutter snipe style sights. No personal experience and since I have and daily carry a Kimber Ultra I probably won't spend the money. One thing I would recommend if you get one is buy some Wilson mags. in my experience more reliable than either Kimber or Colt factory mags for serious social work. If you get one how about giving us your impression of it.
