The liner is pre-installed!!! - TRYBE Defense Glock 19 9mm Pistol Slide - Version 1

Tales of a noobie:

At first, I hadn't realized that the slide comes "naked" and that I had to buy a slide kit to complete it. So, I purchased a kit and waited patiently for it to come. I watched a few videos, read a Glock assembly book on Kindle, and felt confident I can assemble the thing. When my kit arrived, everything went smoothly - EXCEPT inserting the fire channel liner. It wouldn't fit and it cracked when I tried to force it in. So, I ordered THREE liners (just in case) and waited again. The new liner arrives and I try to push one in. Same thing: it wouldn't go. That's when I decided to inspect the channel with a flashlight. After noticing something appears to already be there, I go online and learn ON THIS SITE, that... (drum roll) Trybe slides are shipped with a liner pre-installed! The slide looks great, the Vortex Viper was easy to install on the cut. Dry firing and sliding all work OK. On Saturday, I'll take it to the range for the real deal.
