OK, I gather few to none have tried the Armory Craft Dual Adjustable CZ trigger in their pistols. I decided to give one a try anyway and ordered one and installed it in my Shadow 2. Install was pretty straightforward without incident. Armory Craft claims the "take-up" or pre-travel adjustment screw should not be used without a short pull trigger kit. I elected to give it a try anyway and I was able to get quite a bit of pre-travel out of my trigger pull in DA mode even though I don't have a reduced pull kit in the pistol. In SA mode there is little discernible difference in trigger pull length, but it does feel shorter no doubt based on the design of the trigger blade. There may be times when you will not be able to get the trigger blade in the pistol with the pre-travel screw installed, but this depends on clearance factors on your specific pistol.
Bottomline is I like this trigger blade without exception. It is a truly flat blade design albeit curved with groves along the face of the trigger rather than just a smooth trigger face. It is about as thin as a trigger blade can be without sacrificing strength. It isn't cheap at around $65.00, but it isn't the most expensive trigger blade option on the market either. I am pleased with it.
