The smoothness is real - LANTAC ESP-S Ultra Smooth Glock Safety Plunger/Spring

I bought this for a build. Once complete, I found my slide could not go back into full battery and the problem was diagnosed as this safety plunger. I thought to myself, how could this be possible with a Lantac product? So I put it in a different slide--smooth as KY. Thats what I get for buying a cheap slide in an exotic cerakote color. However, I insist that it is on-par with the L2D plunger.
