This is my first "Glock" and I decided to build it exactly the way I wanted, using the parts and manufacturers I stand behind. I've come to find out I have expensive taste.
Instead of giving a long breakdown of what everything is, I'll just list the manufacturer names I used in the build.
Polymer 80 - Frame
Thrash Tactical - Slide
Magpul - Magazines and Mag Well
Streamlight - Weapon light
Killer Innovations - Barrel
Kineti-Tech - Trigger
Zev Technologies - Spring Kit - Skeleton Striker - Tunsten Guide Rod
Tru Glo - Sights
Wolff - Marine striker cups
Ghost - Disconnect
Phlster - Arc weapon light switch
Strike Industries - +5 magazine extension/base-pad
I hand polished all internals, Hand filed the RMR cover to match the slide serrations, modified the mag release and machined/hand filed the extended button as well as did the Cerakote work.
