REMIX: Smith & Wesson M&P 9/40 Flat-Face Trigger

I've added the files with safety features in place. However, please note that this is still a work-in-progress project and I offer no guarantees for its functionality. It's designed to be compatible with a small compression spring, similar to the APEX trigger. Four variants are available: long, short, long with serrations, and short with serrations in M&P style. Due to my small hand size, the shorter versions fit me better and I find it easier to index my finger on them. Next up is incorporating trigger safety features into the design. With my settings, I had to drill out the holes to match the pin diameter and sand down the front section for proper fitment. Adjusting pre-travel is also an option (see attached image). I've experimented with various triggers, starting with the APEX Competition Action Enhancement Kit featuring a trigger bar loop adjusted according to this tutorial (https://www.youtube.com/watch?v=zMLv_JaoSkU&feature=youtu.be). However, I found that using the Adaptive_Concepts trigger from Thingiverse (http://www.thingiverse.com/thing:1000835) resulted in tighter groups, so I tweaked it accordingly. Caution is advised when using this trigger - it's not recommended for concealed carry due to its lack of safety features. Use at your own risk and only if you're familiar with the process.
