NDZ stainless Firing Pin Liner

[Alaska]

I just ordered a NDZ stainless firing pin channel liner to replace the Glock 20 plastic one.
Anyone use this in their Glock ? Dropped right in unlike the orginal plastic one very easy and smooth first stage trigger replaced the firing pin plastic sleeve with a Stainless Steel one also and added Turbo cups with a 6 pound Wolff spring.
