Just installed the flat trigger in my Shadow 2. Stuart was kind enough to contact me after I placed my order to ask what disconnector I already had installed. Turns out if you have the stock disco in it you also need the CZC DA Short Disconnector, which he sent to me. I got both parts installed and everything works with no fitting required. DA feels really good, SA took me about 5 mins of dryfire to get used to since the trigger breaks past the 90 deg mark. I didn’t measure my SA pre-travel or reset, but I think both have been reduced.
Hitting the range tomorrow to do some live fire. I’m hopeful it all goes smooth since I’m really digging the feel of the flat trigger over the curved.
