Description
The EAA Girsan Witness 2311 CMXX 9mm 4.25in 17rd Black is a compact, compensated double-stack 1911 built for urban carry and home defense. At $1,060.96, it delivers a factory-ported barrel, optics-ready slide, and 17+1 capacity in a package that ditches the grip safety for an ambi thumb safety and automatic firing pin block. This isn’t a range toy — it’s a daily driver for shooters who need fast follow-ups and reliable feeding in tight spaces.

Key Features
- Compensated 4.25-inch barrel — Why it matters: Reduces muzzle rise for faster, more accurate follow-up shots in defensive scenarios, especially at indoor ranges or tight hallways.
- Optics-ready slide with RMSc footprint — Why it matters: Mount a micro red dot without milling, giving you a co-witness with the fiber-optic front sight for low-light target acquisition.
- 17-round double-stack magazine — Why it matters: Carries nearly double the capacity of a standard 1911, matching modern duty guns while keeping a slim grip for concealed carry.
- Ambidextrous thumb safety and no grip safety — Why it matters: Faster engagement for left- or right-handed shooters, and eliminates one more step between draw and first shot under stress.
- Black Cerakote finish — Why it matters: Resists holster wear and corrosion from sweat or humidity, keeping the gun looking fresh for daily carry in urban environments.
Who It’s For
This pistol is for the city CCW holder who wants a 1911-style trigger and ergonomics but needs modern capacity, a compensator, and optics compatibility. Apartment dwellers who prioritize stopping power and quick follow-ups will appreciate the balance between size (4.25-inch barrel) and weight (28 oz). It’s also a solid choice for shooters transitioning from a traditional 1911 to a more practical EDC platform.
Pros & Cons
Pros:
Factory-compensated barrel saves you $200+ on aftermarket porting.
17-round mags mean fewer reloads in a defensive situation.
No grip safety simplifies the draw stroke.
Cons:
The aluminum grip module can feel slick under heavy sweat — consider stippling or a grip wrap for carry. Also, the RMSc footprint limits you to smaller optics like the Holosun 407K or Shield RMSc; full-size dots won’t mount without an adapter plate (not included).
Comparison vs. Competitors
| Feature | EAA Girsan Witness 2311 CMXX | Zev Technologies OZ9 Compact | Agency Arms Syndicate |
|---|---|---|---|
| Caliber | 9mm | 9mm | 9mm |
| Barrel Length | 4.25 in (compensated) | 4.25 in | 4.14 in |
| Capacity | 17+1 | 15+1 | 17+1 |
| Optics Ready | Yes (RMSc) | Yes (RMR) | Yes (RMR) |
| Price | $1,060.96 | $1,899 | $2,495 |
| Weight (unloaded) | 28 oz | 24 oz | 27 oz |
The Girsan undercuts both competitors by $800+ while offering a factory-compensated barrel and higher capacity than the OZ9. You lose the RMR footprint found on the Zev and Agency, but for the price difference you can buy a quality optic and still save money.
FAQ
Does the EAA Girsan Witness 2311 CMXX come with extra magazines?
Yes, it ships with two 17-round steel magazines in the box.
Is this pistol compatible with standard 1911 holsters?
Yes, the frame dimensions and trigger guard shape match the 1911 pattern, so it fits most standard 1911 holsters. However, holsters designed for a railed 1911 or with an open muzzle work best to accommodate the compensator.
Can I install a red dot without buying an adapter plate?
Yes, the slide is cut for the RMSc footprint, so optics like the Holosun 407K, 507K, or Shield RMSc mount directly. Larger footprints (RMR, DeltaPoint Pro) require an adapter plate.
What is the warranty on this pistol?
EAA covers the Witness 2311 CMXX with a one-year limited warranty against manufacturing defects. You can register the warranty online within 30 days of purchase.
