Griffin Armament's MK2 9mm Brings True AR Ergonomics to PCCs

Griffin Armament's MK2 9mm takes the pistol-caliber carbine concept and drags it into AR-15 territory, swapping nostalgia for function without losing the stuff that made the PCC fun in the first place.

Key points

• Magazines: The MK2 9mm runs Metal Form Colt-pattern steel stick mags with a true double-feed design, which TFB's Darwin N. says load and feed more reliably than single-feed Glock mags, plus consistent last-round bolt hold-open.
• Magwell and feed ramp: Griffin Armament built the lower's magwell to natively fit Colt-pattern mags (no adaptor) and added a proprietary 17-4 nitrided feed ramp secured by three Allen screws for centerline cartridge delivery.
• Receiver and controls: The forged receiver set carries full ambidextrous controls, including bolt catch/release, mag release, selector, and Griffin's SN-ACH Gen 2 suppressor-optimized charging handle.
• Fit and finish: The reviewer's test gun, a 4.5-inch model paired with a Griffin Sportsman Ultralight HD silencer, arrived snug from the factory with no need to adjust the included tension screw.
• Cost: Factory magazines run $47.95 to $57.95 in 10-, 20-, and 32-round capacities, pricier than Glock-pattern mags but built specifically for PCC use.

Quick take

If you've been waiting for a PCC that handles like a modern AR instead of a dressed-up SMG clone, the MK2 9mm looks like a serious contender, at least based on TFB's early hands-on impressions.
