Questions & Answers
Will this work with a polymer 80 frame?

It certainly will since the P80 frame is based off the Glock Gen 3 format. We recommend taking your time when building the P80 frame, this is performance slide with precise tolerances. The better your frame turns out, the better the slide assembly will perform.

Does this come with the channel liner installed? Or other parts? Expert Answer

Please contact the manufacturer for that information. https://www.l2dcombat.com/contact
