Apex is the absolute best - Apex Tactical Specialties Glock Gen 5 Action Enhancement Kit

I can’t say enough about these triggers. My first trigger swap (full kit) was for my m&p shield 9mm and it improved the trigger by an astronomical amount.

I recent swapped the trigger on my 19x due to the blade being uncomfortable and the amount of slack and lack of a crisp break was getting to me.

I did a full kit (trigger shoe, trigger bar, and trigger disconnect) and it made a solid difference. Very crisp break with a little take up, and the reset is short and pronounced. Live fire compared to dry firing is even better.
