Works great forgot what parts were used to assemble it. i know it has truglow sights and runs flawlessly. I just cant get used to striker pistols and attempted to customize mine to see if i would like them more. 

Slide has an RMR Cut with a plate to cover if no red dot is desired.
Blacked out rear sight with red fiber optic front post.
Slide is mildly styleized with cuts.
