The Panzer Arms ARP9 is a compact 9mm semi-automatic pistol-caliber platform built around a 6.5" 4140 carbon alloy steel barrel, blowback operating system, 7075 hardened aluminum upper/lower receiver set & Glock-pattern magazine compatibility. It also brings adjustable flip-up sights, M-LOK furniture, a full-length top rail & a tri-lug/1/2x28 muzzle setup, making it a handy range, defensive or vehicle-friendly PCC-style pistol. Performance is centered on simple blowback reliability, compact handling & practical 9mm capacity from included 15 & 33 round magazines. Panzer Arms is better known for tactical shotguns, but the ARP9 shows the company pushing into the PCC space with a lightweight aluminum build, familiar AR-style controls & enough modularity to keep accessory people busy.
