Griffin Armament looks to redefine the 9mm Pistol Caliber Carbine (PCC) market with the introduction of their MK2 9mm PCC series. These firearms represent a leap forward in design and functionality, offering a fully ambidextrous platform built around the popular AR-15 architecture. What sets these PCCs apart is their status as the first on the market to feature a fully ambidextrous control suite coupled with a forged 7075-T6 receiver set.
The MK2 9mm series is compatible with Colt-style SMG magazines, accommodating 10, 20, and 32-round capacities from Colt or Metalform. A notable feature is the inclusion of a 1/4x28 nylon-tipped tension screw within the lower receiver. This allows users to fine-tune the upper-lower fit to their preference, ensuring optimal performance and minimizing any unwanted play. This level of customization, combined with the familiar AR-15 ergonomics, makes the MK2 9mm PCC a natural and intuitive platform for both seasoned shooters and newcomers alike.
Griffin Armament has taken a critical look at the traditional Colt 9mm system and implemented significant improvements. Rather than relying on a magazine well adapter, the MK2 9mm's magazine well is natively sized for Colt SMG magazines. This eliminates a potential point of failure and ensures a more reliable feeding system. Furthermore, the proprietary feed ramp has been meticulously engineered to guide cartridges flawlessly into the chamber, a marked improvement over the original Colt design. The feed ramp's robust "whistlenotch" attachment, secured by three allen screws, further enhances feeding reliability.

Another key enhancement is the combined ejector and bolt catch extension. This streamlined component eliminates the need for the often finicky "ejector adjustment" associated with the original Colt system, simplifying maintenance, and ensuring consistent performance. This focus on user-friendly design and reliable function is evident throughout the MK2 9mm platform.
The internal mechanics of the MK2 9mm PCC have also been refined. A weighted brass buffer and a proprietary action spring work in concert to minimize bolt carrier group travel, preventing casings from becoming lodged in the fire control pocket. This combination results in a remarkably smooth and virtually recoil-less shooting experience, making the MK2 9mm PCC a joy to shoot.


Griffin MK2 9mm 4.5" Pistol
The trigger system is another area where Griffin Armament has gone the extra mile. The MK2 9mm PCC comes standard with Griffin's new adjustable 2-stage trigger. While factory-tuned for immediate use, the trigger allows for user adjustments to overtravel and second stage/disconnector engagement, catering to individual preferences for a more refined trigger feel. This Milazzo-Krieger style trigger combines high-quality materials and precise engineering for exceptional performance.
The Griffin MK2 9mm PCC is available in three barrel lengths: 4.5", 9.5", and 16". The shorter barrel models, 4.5" and 9.5", come equipped with a Griffin 3-Lug barrel adapter. This adapter is designed for use with Griffin suppressors such as the Sportsman Ultra Light HD .36 or Bushwhacker .36, when they are fitted with a 3-Lug booster interface.

The 16" model of the Griffin MK2 9mm PCC features a Griffin Taper Mount Flash Hider Muzzle Device. This device ensures compatibility with Griffin Taper Mount suppressors. Additionally, it can be used with any HUB-mount suppressor that utilizes a Griffin Taper Mount (Plan-A) HUB interface.
The Griffin MK2 9mm PCC series offers a comprehensive suite of ambidextrous controls, including magazine release, bolt catch and release, charging handle, and safety selector, ensuring ease of use for both left- and right-handed shooters. Featuring a durable Type III hardcoat anodized finish and a 416R stainless steel HEDP 9mm barrel for longevity and performance, these PCCs also boast an MSRP of $1499.95 for all models. Backed by Griffin Armament's Perpetual Lifetime Warranty, the MK2 9mm PCC series represents a significant advancement in the 9mm carbine market.
