I had purchased this parts kit to install on a ZEV slide (came with firing pin channel liner, pre-installed), with a ZEV barrel, for optimal compatibility. The parts fit the slide perfectly with no need to do any tinkering, whats...

Good parts kit

by Greg, Verified Owner from TX, United States Written on April 22, 2025
I installed this parts kit into a Live Free Arms slide. The slide cycled smoother than when I installed a different parts kit into the slide. I have yet to shoot it.
Pros:
  • EASY INSTALL
Cons:
  • None

The parts fit the slide perfectly with no need to do any tinkering, whatsoever. Placing the slide on my Gen 3 frame, I found operation to be flawless on the first dry rack and fire, and during subsequent dry firing. Next comes the range trials, which I expect to go just fine.
Pros:
  • Fit & finish perfect, no flaws
  • compatability
Cons:
  • None
Best Used for:
  • ZEV slide and barrel
