I'm telling you, all of this advice is great, but NONE is going to be top notch for the price as this nugget right here:
Glock_made trigger, Zev V4 connector, Zev plunger. That's it. Install yourself, use stock springs. The glock Made company in newer, the trigger they make is TOP NOTCH. I believe the website is OCCUSTOMTRIGGERS... They are $35 I think.
Try it, if you don't want it, send it to me, I'll buy it off of you. But I promise you'll never look back. If you need any more testament, I exchanged ALL of my glock triggers with them. Including the one done by salient, my pyramid, my fulcrum, and my Vogel trigger.
I'm interested in his trigger bar. Do you have any idea what kind of weight you are averaging with your set up?
