A Folding 12GA Shotgun?! The Panzer FS1 Pro

Overview of the Panzer FS1 PRO Folding Shotgun

The video introduces the Panzer Arms FS1 PRO, a semi-automatic 12 gauge shotgun with a distinctive folding design. It sits around the $450 price range and is highlighted for having a large number of built-in features rather than being a basic budget option. The host explains that the plan is to walk through the technical specifications, verify any details as needed, and then wrap up with overall impressions. The focus is on what sets this model apart from other Panzer shotguns, particularly the folding capability and how it integrates with the shotgun’s tube-fed, gas-driven system.

Gas System, Construction, and Core Features

The FS1 PRO uses a gas-driven, tube-fed system, which the presenter notes has been reliable in Panzer’s lineup compared to some of their magazine-fed designs. The receiver is made from 7075-T6 aluminum and the barrel length is 18.5 inches. It includes fiber optic sights, with green inserts at the rear and a red insert at the front. The handguard is polymer and features removable Picatinny rail sections on the bottom and left side. The shotgun uses a synthetic buttstock with an integrated cheek riser and multiple match saver shell holders, including on the bottom of the stock and on the right side of the receiver. Magazine capacity is 4+1 standard, or 7+1 when using the included magazine extension, and the receiver is hard anodized.

Chokes, Barrel Shroud, and Folding Mechanism

The shotgun is chambered for 3-inch 12 gauge shells and ships with interchangeable chokes. One choke comes pre-installed, and the box includes a choke tool along with an additional choke, giving options for pattern selection. A barrel shroud or cover sits over the top of the barrel to protect the support hand, especially for shooters who tend to use a C-clamp style grip similar to an AR-15. The defining feature is the folding action: the receiver splits into two sections rather than functioning as a traditional break-barrel. Rounds must still be loaded through the magazine tube, but the gun can be folded for storage or transport. The folding mechanism operates regardless of trigger position, and a Picatinny rail runs along the top of the aluminum receiver.

Dimensions, Furniture, and Sling Mounts

The folding mechanism is released by an aluminum button located near the rear fiber optic sight. Pulling back on the serrated section allows the receiver to slide and separate. When unfolded, overall length is about 41 inches. Folded, the shotgun measures approximately 26 inches, making it significantly more compact, though the host describes it more as a duffel bag shotgun than a true backpack gun. The grips and furniture are polymer, including the pistol grip. Sling attachment points are provided at the bottom rear of the stock and at the front of the gun, allowing a traditional two-point sling setup. When folded, the sling points sit relatively close together, so attaching a sling is suggested when the shotgun is in its extended configuration to avoid interference.

Trigger, Safety, and Locking Mechanism

The FS1 PRO uses a crossbolt safety and a single-stage trigger. The presenter notes that Panzer shotguns have generally had good triggers and describes this one as feeling solid, with a clear wall and a distinct break. The charging handle is knurled, providing a more secure grip when cycling the action. The locking mechanism that keeps the receiver together when unfolded is described as robust, giving the impression of a well-built system. The shotgun can be folded and then quickly brought back into a ready position, and the host demonstrates that it can be handled and manipulated confidently without the lockup feeling loose or fragile.

Weight, Adjustable Cheek Riser, and Final Thoughts

The shotgun’s weight is measured on a scale at approximately 7.6 pounds, slightly under the host’s initial estimate of around 8 pounds. The adjustable cheek riser on the synthetic stock is shown to move smoothly and to provide a comfortable cheek weld, which should help align the shooter’s eye with the fiber optic sights or any optic mounted on the top Picatinny rail. The host emphasizes that this FS1 PRO is a new folding model from Panzer and invites user feedback and reviews from anyone who has experience with similar Panzer folding shotguns. The video closes with the observation that the shotgun’s folding design is a unique, practical feature on a tube-fed semi-auto platform, and there is interest in taking it out for live-fire testing.
