I replaced the trigger on my Glock 43x. The stock trigger was pinching my trigger finger after puttint 200 rounds through it. I got a blister and figured it's time to replace the trigger. I put 200 rounds through this one and it works great with no pinching. I thought it was a little pricey compared to other 3 party triggers but for me it was worth it. I like the red color and highly recommend it.
