What Makes a 2011 Pistol?
If you’re trying to wrap your head around what defines a “2011” pistol, it really comes down to one simple idea: evolution. The 2011 is a modern twist on the legendary 1911 design, incorporating double-stack magazines for higher capacities.
Now, while Staccato (formerly STI) owns the official “2011” trademark, the design itself has caught on with other big names in the firearms world. Think Kimber 2K11, Springfield 1911 DS Prodigy, or the Girsan Witness 2311. These are all variations on the same modular design concept.
What really sets the 2011 apart, though, is its modularity. Unlike the original 1911, where the grip and frame are all one solid piece of metal, the 2011 splits these components. This allows for the use of polymer grips, which not only reduce weight but also provide options for customization.
Thanks to these updates to the 1911, the platform has become a favorite for competitive shooters, law enforcement pros, and everyday carriers alike.
Staccato HD P4 Review: Unique Features & Updates
Glock Mags Compatibility
The most dramatic feature differentiating the Staccato HD P4 from traditional 2011 pistols is the use of Glock full-size 9mm magazines, including Mechar steel magazines that ship with the firearm.
Historically, one of the 2011 platform’s weak points was its proprietary magazines. Glock mags are cheaper, easier to find, and a bit more reliable than the proprietary magazines 2011s have been stuck with for years. Plus, if you’re part of an agency already using Glocks, logistics just got a whole lot simpler.
Shooters worried this change might affect reliability can be reassured. The HD P4 has been tested extensively with both factory and aftermarket Glock mags, like Magpul PMAGs, and the results are stellar. Feeding is seamless, ejection is smooth, and performance is consistent.
Optic Mounts Directly
Optic mounting has been another area of reinvention for the HD P4. Departing from previous models, the HOST (Hands-On Sight Technology) system eliminates the need for bulky adapter plates. Instead, the pistol accepts any popular optic that uses the RMR, RMR HD/SRO, ACRO, or DPP footprint via a slim plate that easily attaches to the slide.
The HOST system means the optic sits closer to the bore axis, which gives a better sight alignment and, thus, improves accuracy during rapid firing. On top of that, the fewer the parts, the lower the chance of screws backing out or losing zero.
Additionally, the rear iron sight has been repositioned in front of the optic, rather than behind it. This not only clears up visual obstruction but also allows you to rack the slide one-handed in emergency scenarios. Whether using a compact dot like the Holosun EPS or larger optics like the Aimpoint ACRO, the setup is intuitive and functional.
Grip Safety Gone
One of the more debated changes on the HD P4 is the decision to ditch the traditional grip safety, a hallmark of the 1911 lineup.
For some, grip safeties are synonymous with an extra layer of peace of mind, especially on 1911/2011 platforms with lighter triggers. They’re designed to reduce the risk of accidental discharge if the manual safety is off, and they make reholstering safer under stress.
On the other hand, some users find grip safeties unnecessary and even a potential liability. For race guns, they are often seen as a point of failure, and some shooters prefer to pin them down for consistent performance.
Moreover, most modern carry pistols don’t feature even manual safeties, not to mention grip safeties, and this hasn’t led to widespread safety issues. That’s because proper holstering and trigger discipline are more important.
So, while grip safeties have their advocates, they’ve also been a sticking point for many shooters, causing grip interference or complicating deployment under stress.
Now, why did the HD P4 go grip-safety-free?
- It allows for a higher beavertail grip, boosting muzzle control.
- Simplified ergonomics, especially for shooters transitioning from other modern pistols like Glocks or SIGs.
- It’s one less thing to think about in dynamic, tactical, or stress-induced conditions.
That said, the HD P4 retains a thumb safety. The safety is firm but not overly stiff, offering confident engagement without risking accidental disengagement.
Duty-Focused Trigger
So, the HD P4 ditched the traditional 2011 trigger mechanism with its arguably redundant grip safety in favor of a Series 80 trigger system featuring an active firing pin block to make the pistol drop-safe and duty-ready. While the Series 80 trigger often gets flak for a mushier feel due to pre-travel, Staccato’s engineering shines here. The trigger pull in the Staccato P4 is clean, predictable, and well-suited for duty use with a moderate pull weight averaging 4.5-5 pounds.
Ambidextrous Controls
Full ambidexterity is a strong selling point of the HD P4. The pistol includes an ambidextrous slide release, manual safety, and a reversible magazine catch. For duty-oriented shooters, these features enhance operational flexibility and reduce training time, as controls are consistent and easily accessible regardless of hand preference.
That said, it’s not all perfect. The thumb safety can pinch if you’ve got smaller hands, and the mag release stiffness might take a bit of getting used to. These quirks don’t overshadow the overall design, but they’re worth noting. Nothing a few tweaks in future iterations couldn’t fix.
Build Quality and Reliability
The HD P4 is built like a tank. The pistol features fully machined steel frame and slide, with no cast or MIM parts, improving durability. For a duty gun designed to take a beating and keep going, that’s a huge win.
Another standout detail is the frame. It nails the aggressive yet sleek Staccato aesthetic fans have come to love, while offering noticeably improved grip ergonomics. Overall, the pistol feels substantial and solid in the hand. The built-in magwell is a chef’s kiss addition that makes reloads incredibly smooth and fast.
Unintentional Engagement of Safety
The most significant issue highlighted in testing is the P4 thumb safety design, which can engage unintentionally if the shooter’s grip strays from the textbook 1911 hold. This flaw compromises reliability, especially in high-stress scenarios where maintaining a perfect grip isn’t always doable.
The thing is, this issue seems pretty rare. Most users haven’t experienced it, and the P4’s reliability still gets lots of praise across the board, even after tough use. There’s no sign that this is a design flaw requiring any kind of overhaul. It’s more likely due to handling nuances or the occasional production inconsistency – after all, it’s a brand new series.
For those concerned, consulting with Staccato’s customer support may provide additional peace of mind. For the vast majority of owners, the safety works just fine.
Range Report
The Staccato HD P4 brings a balanced but distinctly “duty-oriented” feel. Recoil is stable and manageable, and generally, the gun handles with confidence. It may not deliver the ultra-luxury shooting feel of enthusiast-focused 1911/2011 pistols. For many professionals, these trade-offs are worth it. The design makes practical sense for field deployment, where functionality and safety win out over finesse.
Despite a heavier trigger, the P4 is inherently accurate, giving strong groupings at medium-range engagements.
Also, the pistol performs super reliably with various types of ammo, from standard ball to defensive hollow points and +P loads.
Key observations:
- The recoil impulse is adequate, allowing quick shot recovery.
- The repositioned rear sight creates a more natural sight picture with optics.
- Precision performance at 15 and 25 yards yielded tight groupings, affirming the gun’s inherent accuracy.
Pricing and Packages
The HD P4 is offered in three packages, ranging from $2,499 to around $3,000. The Standard package includes the basic pistol with two magazines, while higher-tier options add features like a Diamond-Like Carbon (DLC) barrel, additional mags, and aesthetic enhancements such as slide cuts. Holster compatibility is currently limited but expected to improve as manufacturers adapt to the pistol’s dimensions. Sure, the price tag positions the P4 in the premium segment, but the value is there.

Final Thoughts
With the HD P4, Staccato has shifted the focus of 2011 pistols onto law enforcement and duty use. By addressing long-standing pain points like magazine reliability, optic integration, and grip comfort, they’ve built a firearm that is as functional as it is innovative.
While the $2,499 starting price and some proprietary components may deter purely recreational shooters, for professionals seeking a reliable, high-performing sidearm, the Staccato HD P4 sets a new standard for what the 2011 platform can achieve. It’s a gun designed for the future, without forgetting the lessons of the past.
The P4 has a 4-inch bull barrel and measures 7.6″ overall, while the P4.5 features a 4.5-inch sight block barrel and measures 8.1″ overall. The P4.5 weighs 34 oz versus the P4’s 32 oz and offers improved recoil management due to the sight block design.
Uses G17/G47 pattern magazines and ships with two 18-round heat-treated carbon steel Mec-Gar magazines. Standard Glock 17 magazines also work perfectly.
Maintains the same grip angle as traditional Staccato models despite using Glock magazines. The grip is approximately 2mm thinner than previous Staccato models.
Dimensions: 7.6″ x 1.6″ x 5.5″ (grip width 1.2″). Weight: 32 oz without magazine.
No, the HD P4 does not fit existing Safariland holsters due to the thicker slide design. But Safariland does offer dedicated 6000 Series P4 HD holsters.
Multiple manufacturers offer dedicated HD P4 holsters, including Slim Fit Holsters, Safariland, Four Brothers, QVO Tactical, GunfightersINC, and TXC. Many are compatible with weapon lights and optics.
Most P4 holsters accommodate the P4.5, though some may have slight trigger guard exposure. Open-bottom designs work best for interchangeability.
The pistol uses the HOST mounting system with dedicated plates for RMR-footprint optics. Optics mount directly to the slide through the plate for secure attachment.
Remove the optic plate cover, install the appropriate HOST plate ensuring the firing pin block spring/plunger is seated, then mount the optic using screws that go through the optic and plate directly into the slide.
Staccato offers HOST plates for RMR footprint, RMR HD/SRO, Aimpoint Acro P2, and Leupold DPP.
Standard capacity is 18+1 rounds. Ships with two 18-round magazines in base package, three in preferred, and four in premium.
Base models include an integrated magwell. Aftermarket magwells like Dawson Precision are available for enhanced reloads.
The HD P4 is larger and heavier but offers higher capacity (18+1 vs 16+1), Glock magazine compatibility, and improved ergonomics. The C2 remains more compact for deep concealment.
It’s the first 2011 with Glock magazine compatibility, mechanical firing pin block, no grip safety, and HOST optics mounting. More duty-focused than traditional race-oriented 2011s.
