I would think, like most models, it's available with the lock or without. I'm a bit intrigued by the name choice, as far as kimber is concerned I wish them luck finding sales in the market. I'm all about 6 shot snubs, but for the msrp I saw we are talking colt d frame territory.
Honestly, you're most likely better off getting one of the well known smiths to mill the slide to your preference. The MOS slides aren't cut very deep, so it's difficult to get even suppressor sights to co-witness.
