Description
The EAA Girsan Witness 2311 C is Girsan's take on the double-stack 1911 format that has taken the shooting world by storm over the past few years. Chambered in 9mm with a 17+1 capacity, it pairs a steel frame and polymer grip module to keep weight down to just 1.6 lbs while maintaining the rigidity where it counts. The slide and barrel are machined from 4140 steel, the frame rails are alloy steel, and the whole package comes in at 8 inches overall with a 4.69-inch threaded barrel capped and ready for a suppressor or muzzle device via a 1/2×28 thread pattern.
What the Witness 2311 C Gets Right Out of the Box
The optic-ready slide is cut to the Shield RMSc/RMS footprint, so small micro red dots like the Holosun 507K or Shield RMSc drop straight in. Fixed contrast sights provide a backup when you're running iron only. The extended beavertail sits high and naturally positions your hand for a solid, high-grip purchase, and the ambidextrous thumb safety snaps on and off with confident positive feedback. An integrated Picatinny-style accessory rail runs along the full-length dust cover, giving you real estate for a weapon light or laser. The skeletonized trigger has a serrated face that gives your finger pad a tactile reference point every time.
Girsan 2311 C Performance and Platform Notes
Reviewers from the NRA's Shooting Illustrated to independent range testers have put the Witness 2311 through its paces and come away impressed with its accuracy and reliability across multiple 9mm load types, from 115-grain FMJ to 147-grain hollow points. Like most 1911-pattern pistols, the action loosens up and smooths out after a proper break-in period, typically around 200 rounds. The pistol uses standard double-stack 1911-pattern magazines, and Check-Mate steel mags are the OEM choice. The 2311 series also carries a limited lifetime warranty through EAA Corp, which is backed out of their service department in Cocoa, Florida. For anyone who has been priced out of the high-end 2011 market, the Witness 2311 C makes a genuinely compelling case for what you can get at this price point.

Frequently Asked Questions
What optics fit the Girsan Witness 2311 C?
The slide is cut to the Shield RMSc and RMS footprint, which is sometimes referred to as the J-Point or Holosun K-series footprint. Optics like the Shield RMSc, Holosun 507K, and similar micro red dots will mount directly without an adapter plate. If you want to run a larger footprint like the RMR, you would need to have the slide machined or use a third-party adapter solution.
Does the Witness 2311 C come with a threaded barrel?
Yes, the 4.69-inch barrel ships threaded at 1/2×28 with a thread protector cap already installed. That makes it ready for most standard suppressors and muzzle devices that use the 1/2×28 pitch common to 9mm pistols. Just remove the cap and thread on your device.
What magazines work with the Girsan Witness 2311 C?
The 2311 C ships with one Check-Mate 17-round steel magazine and is designed to accept standard double-stack 1911-pattern magazines. Check-Mate mags are the OEM choice and tend to be the most reliable fit. Some users have reported varying results with third-party 2011-pattern mags, so it's worth verifying fit with your specific magazine before relying on them heavily.
How does the Witness 2311 C compare to more expensive 2011-style pistols?
For the price, the 2311 C delivers a genuinely solid feature set: steel frame, optic-ready slide, threaded barrel, ambi safety, and full-length rail in one package. Independent reviews have noted strong out-of-the-box accuracy and reliable feeding across multiple load types. The trade-off compared to higher-end options like a Staccato is primarily in trigger refinement and fit-and-finish details, but the core platform is capable and the 2311 series has a real aftermarket and customization ecosystem growing around it.
Does the Witness 2311 C have a grip safety?
Yes, like traditional 1911-pattern pistols, the Witness 2311 C includes a grip safety in addition to the ambidextrous thumb safety. Both must be properly engaged for the pistol to fire, which is standard for this platform. Shooters new to the 1911 design should spend some range time getting comfortable with a consistent grip that fully depresses the beavertail grip safety on every shot.
What holsters fit the EAA Girsan Witness 2311 C?
Holster fit for the 2311 series can take a little research since the accessory rail dimensions and overall profile differ slightly from the more common Staccato or Springfield Prodigy 2011 platforms. Your best bet is to look for holsters specifically made for the Girsan Witness 2311 or contact holster makers directly with the model specs. Kydex custom shops and brands like Safariland that offer model-specific fits are the most reliable route.
