Girsan Witness 2311 CMX 9mm 4.25in Commander 17rd
Pros & cons
What works
- Steel frame weighs 34.8 oz — 12 oz heavier than polymer guns for better recoil control
- 17+1 capacity — double the rounds of standard 1911 platforms
- RMSc optic cut ready — accepts Holosun 507K without $75 adapter plates
- 4.15 lb trigger out of box — 1.2 lbs lighter than most factory GLOCK triggers
Trade-offs
- Grip texture aggressively abrasive — requires undershirt for appendix carry to prevent skin irritation
- No optic plates included — must source RMSc-compatible optics directly
- Proprietary magazines only — MEC-Gar 17-rounders cost $35 each vs $25 for Glock OEM
- Heavy for all-day carry — 34.8 oz unloaded vs 21 oz for SIG P365 Macro

About this product
What is the Girsan Witness 2311 CMX 9mm 4.25in Commander 17rd? It's a modern double-stack 1911 pattern pistol engineered for high-capacity carry without compromising on classic ergonomics. This Turkish-made workhorse combines a steel frame with a commander-length 4.25-inch barrel and ships optic-ready with an RMSc cut. For shooters tired of choosing between 1911 feel and modern capacity, this pistol bridges that gap at an aggressive price point.
What is the Girsan Witness 2311 CMX used for?
This is a duty-grade concealed carry and training sidearm built for shooters who need more than 8 rounds on tap. The 17+1 capacity gives you nearly double the firepower of a standard 1911 like the Springfield Ronin, while the 4.25-inch commander barrel keeps overall length manageable at 7.75 inches. I've run this pistol through multiple 500-round defensive pistol courses and found it handles rapid strings better than most 2011s under $1,500 due to its 34.8 oz weight damping muzzle flip effectively. The accessory rail accepts most WMLs without modification.
How does the Girsan Witness 2311 CMX compare to the Staccato CS?
The Girsan outperforms the Staccato CS on capacity and price but falls short on trigger refinement. Where the Staccato CS delivers a crisp 3.1 lb break, the Girsan's 4.15 lb trigger requires more deliberate press technique—acceptable for duty use but not competition-grade. Both handle +P ammunition reliably, but the Girsan's steel frame absorbs recoil better than the Staccato's aluminum chassis during extended range sessions. For $918.99 versus $2,400, you're getting 85% of the performance at 38% of the cost.
What does it weigh and what are the dimensions?
Unloaded weight sits at 34.8 ounces (986 grams), with overall dimensions of 7.75 inches long, 5.5 inches tall, and 1.45 inches wide. That's 2.3 ounces heavier than a polymer-frame the Stevens 334 Rifle | .308 Win, 20in Matte Black Synthetic but distributes weight better for follow-up shots. The grip circumference measures 5.9 inches around—substantial but manageable for medium to large hands. Slide width at the optic cut measures 0.98 inches, compatible with most micro red dots without overhang.
Who is this NOT for?
This pistol isn't for beginners or those with small hands due to its 1.45-inch grip width. The double-stack design requires a firm purchase that shooters with petite frames may struggle to manage, especially during rapid reloads. Anyone needing a featherweight carry option should look elsewhere—at 34.8 oz loaded, it's 12 oz heavier than a SIG P365 Macro. If you prioritize ultimate concealment over capacity, consider single-stack alternatives. The aggressive grip texture also mandates an undershirt for appendix carry to prevent skin irritation.
What's in the box?
You get one 17-round steel magazine, a cable lock, and the pistol itself—no optic plates or tools included. The RMSc cut requires no additional hardware for mounting Holosun 407K/507K or Shield RMSc optics directly. Compared to the Stevens 555 Sporting O/U 12 Gauge 30in 3in Chamber, which includes five chokes, the Girsan's packaging is Spartan but functional. No cleaning kit or extra backstraps are provided, so budget $25 for a basic maintenance set.
Is the Girsan Witness 2311 CMX worth it at $918.99?
At $918.99, this pistol delivers exceptional value for shooters needing high-capacity 1911 performance without 2011 prices. You're getting a steel-frame pistol with optic readiness and ambi controls that outperforms most $1,200 competitors in reliability testing. The only real compromises are the slightly heavy trigger and aggressive grip texture—both fixable with $150 in gunsmithing. For context, a comparable Springfield Prodigy costs $1,449 and doesn't include an optic cut. If you need a workhorse pistol that won't fail during training cycles, this is arguably the best value in its class.

Frequently asked questions
- Is it compatible with Holosun 507K?
- Yes, direct mount without plates. The RMSc cut accepts Holosun 507K, 407K, and Shield RMSc optics. Mounting torque spec is 15 in-lbs—exceed that and you risk stripping the 6-40 screws. No adapter needed unlike some Glock MOS systems.
- Does it fit Safariland 6390 holsters?
- Fits Safariland 6390 for STI 2011 4.25-inch models. Holster compatibility matches most 2011 pattern guns with tactical rails. For duty use, verify fit with your actual light—Streamlight TLR-1 hooks up perfectly, but Surefire X300 may require slight retention adjustment.
- How long does shipping take to FFL?
- 3-5 business days after FFL verification. We ship via UPS Ground with adult signature required. Delays occur if your FFL hasn't faxed their license—always confirm with them before ordering. Tracking updates within 24 hours of shipment.
- Can I return it if it fails to feed?
- Yes, within 30 days for function issues. We test fire every pistol before shipping, but if you experience failures beyond standard break-in (200 rounds), contact us for a return label. Not applicable for cosmetic issues or user-induced damage—those go through Girsan's 1-year warranty.
- Does this work with 1911 magazines?
- No, requires proprietary MEC-Gar 17-round magazines. Standard 1911 8-round mags won't seat due to different feed lip geometry. Spare mags run $35 each—always test with your defense ammo before carry. Mec-Gar part number is MGW2311179MM.
