Works great and easy to install
The difference this kit made was amazing. I added it to a new FCU that came with an OEM curved trigger. Trigger pull weight went from about 4.5-5 to 2-2.5 using the kit’s “competition” parts! Some reduction in weight was expected but less spongy, very smooth break and no over-travel. I was so impressed with this kit when I took it to the range on a full P320 build, I immediately picked-up another flat trigger kit for my SXG build. You will not be disappointed!
Great competition trigger kit. Loved it enough I bought one for my Legion.
Great trigger and with this kit my X-Ten Endure Comp and my Agx Legion both are just under 3 pounds now. The kit is a little bit of a challenge but with YouTube I installed it myself. The gold trigger looks great on my Endure Comp.
Love iit
