I've noticed that. Ice also been told that it, and the slide stop version from the MHS submission, will be available this year, but could not get a timeframe. I'm seriously considering modifying both myself, but would like to get spares first, in case I mess them up (or to return it to stock, before selling). But, as it is, my groups are better with the P320 than with any other gun I've owned; past or present, and I am still amazed at the trigger, straight out of the box.
