Excellent functionality and reliability
I have installed this kit in a polymer 80 pf9ss.
The results so far with 100 rounds of Winchester White box standard 115 grain has been reliable ignition and positive ejection at the 4:00 position. I could have set a bucket and as long as I fired from one stance the spent brass fell precisely.
I polished the sear and contact surfaces for an ultra smooth action. Positive reset and average Glock style take up.
