The Final Edition is the closing trim of Wilson Combat's Division 77 Project 1, a double-stack 9mm built on the EDC X9 aluminum X-frame with a 5-inch stainless Tri-Top slide, a 5-inch ported bull barrel, and a flat 3.5 to 4.5 lb trigger. Wilson Combat published the configuration on June 12, 2026 with a Black Armor-Tuff slide, a black anodized frame, and a polished stainless barrel finished with black flutes. The run is capped at 500 guns and the first 100 ship in the Limited Edition box with a metal case and a Division 77 challenge coin.

Division 77 is Wilson Combat's skunkworks brand for limited, experimental projects. Each release exists for a defined production window, the design files get archived, and the configuration does not return. Project 1 is the first design that has cycled through its full release calendar, which started with the Black & Copper, Color 2 (Black & Green), and Ghost Edition runs in 2025 and now closes with the Black & Stainless Final Edition. After the 500-gun cap sells through, Project 1 is permanently retired and the next Division project takes the production slot.

The 5-inch ported bull barrel cuts felt recoil 42 percent versus a standard EDC X9 by venting top-side gas immediately behind the muzzle. Wilson Combat machines the porting directly into the bull barrel rather than threading a separate compensator on, which keeps overall length at 8.7 inches and preserves holster fit with any rig built for a 5-inch 1911 or 2011. The Final Edition leaves the barrel polished stainless with black flutes cut into the OD, which differentiates the run visually from the matte stainless and copper PVD configurations that preceded it.

The downside of an integral port is permanence. Indoor ranges that ban ported guns also ban this barrel; a buyer who needs a non-ported option should look at the standard EDC X9 instead. The upside is durability. Bolt-on compensators carry mounting threads that wear, loosen, and require periodic re-installation; the Project 1 port is part of the barrel forging and does not move. For shooters running 50,000 plus rounds a year through a single barrel before re-barreling, the integrated design is the lower-maintenance path. For full context on how the EDC X9 lineage built up to this point, our Wilson Combat BULWARK coverage walks through the platform that shares the Project 1 Pin architecture.

Project 1 Pin Technology accepts the RMR, RMSC, and DeltaPoint Pro footprints directly into the slide through indexing pins. The Trijicon RMR cut covers the Holosun 507C and 508T, the Leupold DeltaPoint Pro cut covers the SIG Romeo1 Pro and Holosun 507COMP, and the Shield RMSc cut covers the Holosun 407K and 507K. The slide ships from Berryville already cut for all three; the buyer drops in the correct pin set and torques the optic. There is no plate purchase, no plate-to-slide gap, and no separate screw stack between the optic body and the slide.

The cost case matters for shooters who run multiple optics on one gun. A typical aftermarket plate runs $80 to $120 and one plate is required per footprint family. A shooter who wants to test an RMR, a 507COMP, and an EPS Carry on a plate-equipped slide pays $240 to $360 in plates plus the cost of buying and selling each plate when switching footprints. The Project 1 Pin system replaces that with two pin sets included with the gun. For optic comparison background and current footprint guidance, see our best carry optics pistols guide.

Wilson Combat retires Project 1 into the Vault after the 500-gun Final Edition ships. That means no further Project 1 guns will be built, the slide and frame SKUs leave the catalog, and the next Division 77 release becomes Project 2. Parts service, warranty work, and magazine availability continue indefinitely under Wilson Combat's standard service policy, the same way the company still supports out-of-production CQB, Sentinel, and Protector configurations from earlier decades. What goes away is new production.

The practical effect is a fixed supply against a known buyer pool. Division 77's earlier runs (Black & Copper, Color 2, Ghost) cleared dealer allocations within weeks and now trade above MSRP on the secondary market. The Final Edition is the last shot at MSRP on any Project 1, which compresses the purchase window for buyers who want one. If a shooter is cross-shopping the Project 1 against a Staccato HD or an Atlas build, our Staccato HD C4X SHOT Show coverage covers the Staccato side of that comparison.

At $4,405 standard, Project 1 lands above a base Staccato XC ($3,499) and Staccato HD ($3,799), below a custom Atlas Erebus or Infinity SVI (typically $5,500 plus), and well above a base EDC X9 ($3,000 to $3,200). The market position is deliberate. Wilson Combat is selling the ported barrel, the Project 1 Pin optic system, and the 500-unit cap as the premium over a standard EDC X9, not as a price competitor to stock Staccato production guns. For a clean side-by-side spec view against the Staccato HD, the Atlas Erebus, and the EDC X9, use our pistol comparison tool.

Against the 2011 segment Project 1 is not a 2011 in the Para/STI/Staccato lineage. It is a Wilson Combat EDC X9 derivative built on the X-frame rather than a metal grip module bolted to a single-stack 1911 frame. That changes the grip ergonomics, the magazine geometry, and the trigger kinematics relative to a true 2011. Buyers cross-shopping this against an HD C4X or an Erebus should hand-cycle both; the X-frame trigger has shorter take-up than a 2011 grip module setup, and the bull barrel sits lower in the slide than most 2011 bushing-barrel builds. For a broader read on premium 9mm double stacks, our best 2011 pistols ranking tracks the segment with current prices and our best 9mm pistols guide stacks Wilson Combat against the full premium 9mm field.

The Final Edition is the cleanest expression of Project 1 that will ever ship from Berryville. Black Armor-Tuff on the slide, black anodized aluminum on the frame, polished stainless with black flutes on the ported bull barrel; no copper PVD, no green anodize, no Ghost stainless. The mechanical content (ported bull barrel, Project 1 Pin optic cut, Advanced RPG guide rod, 1-inch-at-25-yard accuracy guarantee) carries over from the earlier runs unchanged. Buyers get the production version Wilson Combat clearly intended as the closing statement on the SKU.

The buy case is narrow and well-defined. For a shooter who already owns an EDC X9, the upgrade pays for the ported barrel and the plateless optic system, both of which are permanent gains on the platform. For a first-time Wilson Combat buyer with the budget, the Final Edition is the last opportunity to buy a Project 1 at MSRP from a dealer; after the 500-gun cap clears, all sales move to the secondary market. The honest caveat is the ported barrel locks the gun out of indoor ranges that ban ports, which makes a standard EDC X9 or a BULWARK the better choice for shooters whose primary range has that policy. If the host range allows ported guns, this is the strongest closing trim in the Division 77 catalog.
