509 and 509T

Cons:
I am amazed at how easy this was to install, follow the video and I was able to knock out 2 guns in no time at all. Best part both guns break at 4lbs on the dot. My 509T is brand new and my full size has a couple thousand rounds through it. Excited to hit the range and see the difference. Great product and excellent communication through the entire process. Can you guys make a crisper sear setup for these?

Just installed it on my 509T and it has a smooth, clean takeup with a crisp break. I paired it with an Apex flat trigger and it feels totally amazing. Will be ordering again once I receive my 509 midsize MRD. Great product made here in the USA. Thank you!

Amazing kit, makes the trigger in my fn 509 tactical feel amazing! Very light and crisp trigger pull. Best $20 I've spent on a gun! Put 2 boxes of ammo threw it and shoots perfectly. I'm much more accurate with it after installing the springs! The install video was super helpful! Also mcarbo is an awesome company, they shipped super fast and kept me updated threw the whole process! Hope I have a reason to business with them again in the future!

Best $20 upgrade to your FN 509

First of all do not loose any spring or parts while assassinating the trigger' sear group.

1) Installation was hairy but doable

2) The Video instructions are excellent

3) Repeat do not loose parts, lay down a big white sheet/towel on your bench/work area.

4) Just follow the video instructions



Trigger pull dropped to 4lb average of 10 pulls



Next,t I am installing another set in my buddy F509
