Smith & Wesson M&P with Apex trigger

[akjunkie]

Apex used to sell the heavy sear spring by itself but I only see it sold as part of a kit now: https://www.apextactical.com/duty-ca...it-mp-9-40-357

Here's a spare trigger bar. The candy cane loop is the part at the end that engages the sear when you pull the trigger: https://www.midwestgunworks.com/page...prod/393050000
Notice how the candy cane is closed practically all the way in the picture. You need to open it up when using an Apex sear. I opened mine up by 1.5mm using a flathead screwdriver. I used a guitar pick as a poor man's feeler gauge.

Thx!
