EAA Witness2311 XXX: 16+1 Compact 2011s From $599 header image

Key Takeaways

  • The Grip Is The Product: EAA cut the Witness2311 grip module by roughly 25 percent, which is the whole point of the XXX series.
  • 16+1 Survived The Diet: A slim Check-Mate magazine, not a capacity cut, is how the grip shrank.
  • $599 And $899: The SC9 XXX takes irons and a grip safety; the CMX XXX adds an RMSc cut, a tuned trigger, and a second magazine.
  • New Magazine, New Ecosystem: The XXX runs its own slim magazine rather than the standard 2011-pattern magazines the rest of the line shares.
  • Drawn For Smaller Hands: Grip circumference, not barrel length, is what kept double-stack 1911s off a lot of belts.

What EAA Actually Changed

EAA's Witness2311 XXX series is two compact double-stack 1911s in 9mm, both with a 3.4-inch barrel and a 7-inch overall length, both holding 16+1, at $599 for the SC9 XXX and $899 for the CMX XXX. The barrel length is not the news. EAA has sold a 3.4-inch Witness2311 for a while now in the Brat, which holds 17+1 on the same short barrel. What changed on the XXX is the part of the pistol nobody usually gets to change: the grip module, which EAA says is approximately 25 percent smaller than the standard double-stack module.

That is a harder problem than shortening a slide. On a double-stack 1911 the grip has to wrap a magazine holding two staggered columns of 9mm, so grip circumference is downstream of magazine width, and the conventional way to slim the grip is to give up rounds. EAA worked the other end instead. Girsan and Check-Mate developed an ultra-slim magazine for the series, and the smaller grip module was built around it, which is how the XXX keeps 16 rounds in a hand filling roughly three quarters of what the standard gun demands.

Two Pistols, One Frame Size

The SC9 XXX and the CMX XXX are the same size gun with different equipment. Everything dimensional is shared, so the $300 spread buys features rather than a different pistol.

How It Compares To The 3.4-Inch Witness2311 EAA Already Sells

The comparison that matters is not against a Staccato, it is against the Witness2311 Brat sitting one shelf over. The Brat is also a 3.4-inch double-stack 1911 in 9mm, it also has a grip safety, an extended beavertail, a full accessory rail, and an RMSc optic option, and it holds one more round at 17+1. Anyone shopping a small EAA 2011 is going to have both in the cart, and the spec sheets look nearly identical until you get to the grip and the magazine.

So the XXX trades one round and the shared magazine pattern for a grip a quarter smaller. Whether that is a good trade is not a universal answer, it is a hand-size answer, and it is the most honest way to shop these two. If a standard 2011 grip already fits you and conceals under your cover garment, the Brat gives you the extra round and magazines you can buy anywhere. If the grip was the thing that made you put a double-stack 1911 back on the counter, the XXX is the only one of the two that solves your problem, and one round is a cheap price for it. Our budget 2011 rankings lay out where the rest of the sub-$1,000 field lands on exactly this question.

Where $599 Lands In The Compact 2011 Field

At $599 MSRP the SC9 XXX is priced under every compact 2011 people usually cross-shop, and the gap is not close. The Kimber KDS9c runs $1,134.99 and the Staccato C2 $2,648, both of which are better-finished pistols with deeper aftermarket support and domestic service. The XXX is not trying to beat them on execution. It is trying to put a 16-round double-stack 1911 on a belt for striker-pistol money.

Inside EAA's own catalog the ladder is cleaner. The full-size Witness2311 CMX runs a 4.25-inch barrel and 17+1 at a $999 MSRP, so the CMX XXX shrinks that gun by 0.85 inch of barrel, an inch of overall length, and a round, and comes in $100 under it at $899. The same optic cut, the same tuned 4.5-pound trigger, and the same ambidextrous thumb safety carry across. Buyers who wanted the CMX but found it too much pistol to conceal now have the version that fits, and they are not paying extra for the privilege.

The caution worth stating plainly is that EAA is an importer, so warranty turnaround and parts support run slower than a domestic brand, and the aftermarket for a brand-new grip module starts at nothing. Holsters are the immediate one. A shell molded for a standard Witness2311 is cut for a grip that no longer matches, so the molded options that fit an XXX exactly will arrive after the pistols do. Line the whole class up side by side in the platform comparison tool before committing, and see our 2011 pistol rankings for where each price tier earns its keep.

Optic And Light Planning

Only the CMX XXX takes an optic without gunsmithing, and the footprint is RMSc. That narrows the shopping list to the compact enclosed and open-emitter sights built on the Shield pattern rather than the RMR-footprint dots that dominate full-size 2011s, which is the correct call on a gun this size anyway. Because the cut sits under a removable rear sight plate, pulling the plate takes the rear sight with it, so plan on the optic being the aiming system rather than a co-witnessed addition to the irons.

Our pistol red dot rankings cover which RMSc-footprint sights hold zero on a short slide, where recoil is sharper and the optic sits closer to the muzzle, and the 1911 and 2011 optic mount guide works through the plate-versus-direct-mill question across the platform. The SC9 XXX ships iron-sighted with no cut, so a red dot on that model means slide work, and at $599 the arithmetic usually favors buying the CMX XXX instead.

Both models carry a 4-slot Picatinny section on the dust cover, which is more useful than the spec line suggests. Compact 2011s frequently ship without a rail at all, so a weapon light is genuinely on the table here. Compact lights sized for a 3.4-inch slide are the ones to look at rather than full-size rifle-adjacent units that will hang past the muzzle. Spec the light, the optic, and the spare magazines together in the build configurator so the total lands where you expected it to.

Frequently Asked Questions

What is the EAA Witness2311 XXX series?
The Witness2311 XXX series is a pair of compact double-stack 1911 pistols built by Girsan and imported by European American Armory. Both are chambered in 9mm, both use a 3.4-inch barrel and a 7-inch overall length, and both hold 16+1 using a slim Check-Mate magazine developed for the series. The SC9 XXX (SKU 395064) lists at $599 with a black Cerakote finish, low-profile 3-dot sights, a grip safety, and an ambidextrous thumb safety. The CMX XXX (SKU 395062) lists at $899 with a two-tone black and tungsten Cerakote finish, an RMSc optic cut under a removable rear sight plate, a tuned 4.5-pound trigger, an auto firing pin block in place of the grip safety, and two magazines in the box. Both carry a 4-slot Picatinny accessory rail.
What is the difference between the SC9 XXX and the CMX XXX?
Three hundred dollars buys an optic cut, a tuned trigger, and a second magazine. The two pistols share the 3.4-inch barrel, the 7-inch overall length, the 16+1 capacity, the compact grip module, and the accessory rail. The CMX XXX adds the RMSc footprint milled into the slide under a removable rear sight plate, a trigger tuned to a 4.5-pound maximum, lightening cuts in the slide, a two-tone finish, and a second Check-Mate magazine. It also swaps the traditional grip safety for an automatic firing pin block, so the CMX XXX has a solid tang while the SC9 XXX has a hinged grip safety. If a red dot is in the plan, the CMX XXX is the one that takes it without gunsmithing.
How small is the XXX grip compared to a standard Witness2311?
EAA puts the reduction at approximately 25 percent against the existing double-stack grip module, achieved by developing an ultra-slim magazine with Check-Mate rather than by cutting capacity. That is the entire engineering premise of the series. On a double-stack 1911 the grip module has to wrap the magazine, so grip circumference is set by magazine width, and the usual way to slim a 2011 grip is to drop rounds. EAA went the other direction and had the magazine redrawn, which is why a grip roughly a quarter smaller still holds 16 rounds.
Does the Witness2311 XXX use standard 2011 magazines?
No. The XXX series feeds from a slim Check-Mate magazine developed specifically for its shorter and narrower grip module. That is a different magazine from the standard double-stack Check-Mate magazines the rest of the Witness2311 line runs, which follow the widely shared Staccato 2011 pattern. It matters when you buy spares and when you plan around a magazine ecosystem: a Witness2311 Brat, a base Witness2311, or a Tisas B9R DS can trade magazines with the broader 2011 pool, and the XXX carries its own. Buy spare magazines for an XXX by the XXX part number rather than assuming a 2011 magazine on the shelf will drop in.
How much does the EAA Witness2311 XXX cost?
MSRP is $599 for the SC9 XXX and $899 for the CMX XXX. For context inside EAA's own lineup, the full-size Witness2311 CMX with a 4.25-inch barrel and 17+1 capacity lists at $999, so the CMX XXX arrives $100 under the gun it shrinks while giving up 0.85 inch of barrel, an inch of overall length, and one round. Against the compact 2011s it competes with, $599 puts the SC9 XXX several hundred dollars under a Kimber KDS9c and roughly two thousand under a Staccato C2.
Is the Witness2311 XXX a good concealed carry pistol?
It is aimed squarely at that job, and grip size is the reason. Slide length decides how a pistol rides in a holster, but grip circumference and grip height decide what pushes a cover garment out at the belt line, which is the dimension that actually prints. A 3.4-inch double-stack 1911 was already carryable; the part that defeated a lot of shooters was getting a hand around a grip built to wrap two columns of 9mm. Taking roughly a quarter out of that module without dropping to single-stack capacity addresses the specific complaint. Shooters with smaller hands, and anyone who found a standard 2011 grip too thick to conceal or control, are the buyers this series was drawn for.

Bottom Line

The first compact 2011 that shrank the grip instead of the round count, at a price that makes the tradeoff easy to accept.

Every compact double-stack 1911 before this one solved the size problem at the muzzle end, where it was easy, and left the grip alone, where it was hard. EAA had Check-Mate redraw the magazine and built a module around it, and the result holds 16+1 in a grip roughly a quarter smaller than the gun it came from. The cost is one round and a magazine that does not trade with the wider 2011 pool, which is a real cost and a small one against what it fixes. At $599 for the iron-sighted SC9 XXX and $899 for the optic-cut CMX XXX, this is the version of a carry 2011 that a lot of shooters have been describing for years, and the cheaper of the two undercuts a Staccato C2 by roughly two thousand dollars.
