Mostly yes, with one real distinction. Both are wide-body, high-capacity descendants of John Browning’s 1911, holding 15–20+ rounds instead of the classic 7 or 8.
The difference is in how the grip is built.
A 2011 uses a two-piece, modular architecture: a metal fire-control frame mated to a separate grip module, often polymer. “2011” is a trademark tied to STI/Staccato, which is why the industry now uses it as a generic label for that modular pattern.
A double-stack 1911 is the broader umbrella term. Some are one-piece, all-metal wide-body frames. Others (including guns marketed as “1911 DS”) use the same two-piece modular approach as a 2011.
So every 2011 is a double-stack 1911, but not every double-stack 1911 is built on a modular grip module. When a shopper searches either phrase, they’re almost always after the same thing: a high-capacity 1911 that feels like a 1911 but carries like a modern duty gun.
This guide treats them together and flags the differences that actually affect you: capacity, grip feel, magazine ecosystem, price, and build quality.
Where the Fierce Grizz GZ9 sits
The Fierce Grizz GZ9 is a double-stack 1911 built on a two-piece body with Cheely grip modules — the same modular architecture Staccato pioneered with its 2011. It holds 19+1 in 9mm, at or above what most name-brand guns in this class carry. Many full-size options top out at 17+1.
If you’re cross-shopping a Staccato 2011 or any 9mm double-stack 1911, it belongs on your list.
Why capacity and grip feel matter
The wide body is the whole point. 19+1 in 9mm means more shooting between reloads for competition and home defense, and a grip that fills the hand for better recoil control.
The tradeoff is honest: a double-stack grip is thicker than a single-stack 1911. It suits medium-to-large hands, and it favors belt or open carry over deep concealment. That’s true of every gun in this category, ours included.
Full-size vs compact: RMR vs RMSC
Fierce builds the Grizz in two configurations. The difference is what sits on top — not the size of the gun.
| Model | What You Get |
|---|---|
| Grizz GZ-9 RMR | Grizz RMR: Cut for the full-size RMR optic footprint, with fiber-optic iron sights. Ships with the rear sight plate, so you can run irons only if you skip the optic. The do-everything range, competition, and home build. |
| Grizz GZ-9 RMSC | Grizz RMSC: Cut for the compact RMSC optic footprint, with no iron sights. A clean, optic-forward setup for a red-dot shooter. |
Both wear a 4.25-inch bull barrel, the same two-piece body, the same Cheely grips, and the same hand fit. Choose the RMR if you want irons and the larger optic footprint. Choose the RMSC if you’re running a compact red dot and want nothing else in the way.
Match the cut to the dot you already own, before you buy.
What Actually Separates Good from Great: Who Built It?
There are two ways to build a double-stack 1911. You can run them down a line, swap parts until they fit well enough, and box them up. Or you can fit them by hand, one at a time.
Fierce has two builders. Whichever one takes your pistol builds all of it, from frame to muzzle. The same hands fit the barrel, tune the trigger, dial the extractor, and dress every surface.
Then that same builder loads your two magazines and shoots it. Not a function check — a live test-fire. Anything that needs attention gets fixed by the person who built it, before the gun ever reaches your FFL.
That matters because the 1911 (single or double stack) is a hand-fit design. The difference between a pistol that runs everything and one that’s picky about magazines and ammo usually comes down to fitting and testing. A gun that isn’t fit well can frustrate you at any price. A gun that is fit well runs clean.
The value argument: $5,000 performance at $3,500
Cross-shop honestly. The premium modular double-stacks from the biggest names routinely run $4,000–$5,000 and up. There are cheaper double-stacks on the market too, and some of them shoot fine — but they’re built to a different process, and you can feel it in the trigger and the fit.
The Grizz sits in between on price and at the top on build method: hand-fit and individually test-fired, at $3,500. Apples to apples on fit, trigger, and capacity, it competes with guns that cost a thousand dollars more.
What you get for $3,495–$3,550:
- 19+1 double-stack 1911 in 9mm
- 4.25″ bull barrel
- Two-piece body with Cheely grip modules
- Hand-fit by a single builder, frame to muzzle
- Individually test-fired before it ships
- Two quality magazines
- Iron-sight plate (RMR model)
- Savior range bag
What About 10mm? The Fierce GZ10 Is in Prototype
The double-stack 10mm 1911 is one of the most-requested and least-well-served corners of this market. Shooters want 10mm ballistics in a high-capacity 1911, and most factory options compromise somewhere.
Fierce has a GZ10 in prototype. It’s been live-fired and ran clean in early testing, and it’s being designed with a ported slide and barrel to tame 10mm muzzle rise for faster, flatter follow-ups.
It won’t ship until it’s right. That’s the whole point of the two-builder model. If you want a hand-fit double-stack 10mm 1911 done properly, this is the one to watch.
Things To Consider When Picking Whats Right For You
Caliber. 9mm for capacity, low recoil, cheap practice, and competition — that’s the Grizz GZ9. 10mm if you want more thump in a double-stack, if and when the GZ10 arrives.
Optic cut. RMR for irons plus the larger footprint. RMSC for a clean compact red-dot setup with nothing else on the slide.
Build method over badge. A hand-fit, test-fired gun is worth more than a bigger logo. Ask any builder whether they actually shoot the gun before it ships.

FAQ (Frequently Asked Questions)
Is a double-stack 1911 the same as a 2011?
Nearly. Both are high-capacity, wide-body 1911s. “2011” specifically refers to the two-piece modular design — a metal frame plus a separate grip module — and is a trademark associated with STI/Staccato, now used generically for that pattern.
‘”Double-stack 1911″ is the broader term and covers both modular guns and one-piece wide-body frames. The Grizz GZ9 uses a two-piece body with Cheely grip modules, the 2011-style architecture.
How many rounds does the Grizz GZ9 hold?
19+1 in 9mm. That’s at or above most full-size guns in this class, many of which carry 17+1.
What is the difference between the Grizz RMR and RMSC?
The optic cut. The RMR ($3,550) is cut for the full-size RMR footprint and comes with fiber-optic iron sights, plus the rear sight plate so you can run irons only. The RMSC ($3,495) is cut for the compact RMSC footprint and has no irons — an optic-forward setup for a red-dot shooter. Both use the same 4.25-inch bull barrel and the same hand-fit two-piece body.
Why does the Grizz cost $3,500 when other double-stacks are cheaper or far more
expensive?
Because of how it’s built. Every Grizz is hand-fit by a single builder from frame to muzzle and individually test-fired before shipping. Premium modular double-stacks from the biggest names often run $4,000–$5,000 and up. The Grizz delivers comparable hand fit, trigger, and 19+1 capacity for $3,500.
Does Fierce make a double-stack 10mm 1911?
A 10mm Grizz GZ10 is in prototype. It’s been live-fired successfully and is being designed with a ported slide and barrel to reduce muzzle rise. It’ll be released only once it meets the standard — no set date yet.
Is a double-stack 1911 good for concealed carry?
The grip width is the same on both Grizz models, so the honest answer is that any double-stack 1911 favors belt or open carry over deep concealment. If you are carrying one, the RMSC keeps the top end cleaner with a compact dot and no irons. The RMR is the better all-around choice for range, competition, and home defense.
Do 2011 magazines work in the Grizz?
The Grizz ships with two builder-tested magazines matched to your gun, so it runs correctly out of the box. Contact Fierce before running third-party magazines to confirm compatibility with your specific build.
