I polished the striker parts and the sear parts when I install this spring kit. Huge!! Improvement. Excellent product, top notch customer service. Email confirmation from the moment I order then at all stages of shipping/delivery and they are still coming. I have referred anyone who will listen to me to your website. I can’t thank you enough. Very helpful detailed videos too

Review

To say I was a bit disappointed with the stock FN 509T trigger is a gross understatement....it was TERRIBLE!! LOL!! So, after already having installed a couple M-Carbo spring kits in other firearms I figured I would give the 509T some M-Carbo love as well. All I can say is....WOW...What a HUGE difference!! There is still a bit of creep but the pull weight was reduced CONSIDERABLY and the reset is super smooth!! My pull weight went from 7.7 pounds stock down to 4.6 with the M-Carbo kit!! That's 3 pounds of pull weight reduction!! Thanks guys for another amazing spring kit!!
