Decided I wanted to do a build figured I would just start with my first pistol plus it's my first non .223.
I bought a yhm 9mm upper with 7.5 inch stainless barrel and dpms pistol hand guard and a2 style flash hider.
Then got a stripped surplus ammo lower
Promag mag adapter
Dpms mil spec lower kit
RRA pistol buffer tube
Ambi sling adapter back plate with nipple cut off
This is going to be my home defense gun and zombie gun. Still have some small plans for it. Shots perfect. Unloaded 2 32 round clips with no prob at all. I do not like the promag mags but they did feed well.

Lol that's my wife's desk. Only problem
I see is I have to push my mags in kind of hard but once they r in there they do not move or anything. Have not gotten to shot it anymore bc I can't shot at my house anymore.
