9mm semi-auto. Selector has fire/safe. 2 10 rd mags. 1 mag with 24 rds. The pistol appears to be a 380ACP. .223 ammo with 30-rd mag and a stripper clip for some of the .223. Nothing real special. You can buy a better 9mm AR semi-auto that loads 32-rd Colt SMG magazines brand new from CMMG. The one pictured below is the PDW. You have to spend $200 and submit a Form 4 as it is an SBR. The 16.1 inch barrel version requires no special paperwork. Both are tack drivers and very reliable.
Correction: the PDW is a pistol. No special paperwork required. It's an SBR if you put a regular stock on in place of the bare buffer tube.
