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?

This kit dropped my trigger pull weight from 8.5-8.8lb to 4.5lbs. I couldn't believe how heavy the pull was in my 509 tactical. It wasnt bad until the wall then it felt like it was stuck. A knocked the sharp edge off the barrel lug polished parts and installed the Mcarbo kit which was very easy once you know where everything goes. Great kit if you want to keep your pistol factory-ish for carry

Super easy install brought my trigger pull down to 4 pound on the dot amazing!

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!
