When it comes to .45 ACP handguns, two platforms consistently spark debate among enthusiasts: the s&w 4506 and the iconic 1911. Both are powerful, proven, and respected, yet they couldn’t be more different in design philosophy, shooting feel, and user experience. Whether you’re a seasoned firearms collector or a new shooter researching your next purchase, understanding how these two compare will help you decide which platform fits your needs.

Below, we’ll break down the history, handling, performance, durability, and overall user suitability of both options. By the end, you’ll know exactly which .45 ACP platform speaks to your shooting style and priorities.

Brief History of the S&W 4506 and the 1911

 

The S&W 4506

Smith & Wesson introduced the s&w 4506 in the late 1980s as part of their third-generation semi-automatic pistol lineup. Made from stainless steel and chambered in .45 ACP, it was designed for law enforcement and shooters who wanted a rugged, dependable, high-capacity alternative to the traditional 1911. The series quickly gained a reputation for durability and simplicity under tough conditions.

The 1911

Designed by John Moses Browning and adopted by the U.S. military in—you guessed it—1911, the 1911 platform has spent more than a century building its legacy. From two world wars to civilian competitions, the 1911 is perhaps the most iconic American handgun ever created. Classic in style but highly customizable, it remains a favorite among competitive shooters, collectors, and defensive gun owners.

Design Differences That Matter

 

Action Type

The s&w 4506 uses a DA/SA (double-action/single-action) trigger system. The first pull is long and heavy, followed by lighter, shorter subsequent shots.

In contrast, the 1911 uses a single-action only (SAO) trigger, famous for being crisp, light, and consistent. This is one of the major reasons 1911s are preferred in competition and precision shooting.

Frame and Construction

Both pistols use steel construction, but the 4506 is built like a tank—thicker, slightly bulkier, and noticeably heavier in the slide and frame. It was designed for duty use, meaning durability was a top priority.

The 1911 offers more variation: steel, aluminum, lightweight builds, and tactical updates depending on the manufacturer.

Ergonomics

The 4506 has a squared, modern grip angle similar to many duty pistols. While sturdy, some shooters find it large, especially those with smaller hands.

The 1911 has one of the most natural-feeling grips in handgun history, with a slim profile and angle that aligns effortlessly with natural aiming point.

Trigger Performance Comparison

 

S&W 4506 Trigger

The DA/SA system offers versatility. The first double-action pull is heavier, requiring deliberate pressure—some shooters love this for safety, others dislike it for accuracy. Once in single-action mode, the trigger becomes crisp and enjoyable, though not quite as refined as a tuned 1911.

1911 Trigger

The 1911 is legendary for its trigger feel. The single-action break is clean, light, and predictable. For shooters who value accuracy above all else, the 1911 remains the gold standard. Many competitive shooters and professionals choose it for this very reason.

Accuracy and Shooting Feel

 

Both guns are capable of excellent accuracy, but their shooting personalities differ.

Accuracy of the 4506

The s&w 4506 is extremely consistent. The weight of the frame helps absorb recoil, allowing for smooth follow-up shots. While the accuracy may not match a high-end match-grade 1911, it’s more than capable for defensive use, range shooting, and even competition in experienced hands.

Accuracy of the 1911

The 1911 is inherently accurate due to tight tolerances and its SAO trigger. High-end models—such as those from Wilson Combat, Dan Wesson, or Nighthawk—are capable of match-grade precision. Even entry-level 1911s tend to perform impressively at the range.

Capacity and Reload Experience

 

S&W 4506 Capacity

The 4506 typically uses an 8-round magazine, similar to standard 1911s, though variants may allow for slight differences. Reloading is straightforward, with a modern magazine release and feed system.

1911 Capacity

Standard 1911 magazines also hold 7–8 rounds, but modern 1911s offer extended magazines and double-stack variants like the 2011 platform. Reloads can be fast and smooth, especially with beveled magwells or competition-ready designs.

Safety Features and Ease of Use

 

S&W 4506 Safety

The 4506 incorporates a manual safety/decocker, which many shooters appreciate for duty or home defense. It allows safe carry in DA mode with the hammer down.

1911 Safety

The 1911 uses a thumb safety and grip safety, offering dual layers of protection. Users must intentionally disengage both, which some appreciate while others find excessive.

Durability and Reliability

 

4506 Durability

The s&w 4506 is widely praised for being overbuilt. Stainless steel construction and robust internal parts make it capable of handling heavy use, adverse conditions, and minimal maintenance. Many retired police officers still swear by their old S&W pistols because “they just run.”

1911 Durability

Durability varies by manufacturer. A well-built 1911 can last generations, but cheaper versions may struggle with tight tolerances or finicky feeding. Because the 1911 design is highly customizable, reliability depends heavily on build quality and proper tuning.

Customization and Aftermarket Support

 

1911 Customization

When it comes to aftermarket parts, the 1911 wins hands down. Shooters can replace triggers, sights, grips, barrels, slides, safeties, hammers—you name it. This platform is essentially the AR-15 of handguns.

4506 Customization

The s&w 4506 has limited aftermarket support. While grips and sights can be changed, the majority of components are proprietary and difficult to source today. For shooters who prefer stock performance without modifications, this may not be a drawback. However, tinkerers may prefer the 1911.

Concealed Carry Considerations

 

Carrying the 4506

The 4506 is large and heavy—more suited for duty holsters than concealed carry. Its weight makes it incredibly recoil-friendly but difficult to conceal, especially in warm climates.

Carrying the 1911

A 1911, especially in Commander or Officer size, is far easier to carry. Slim grip panels, single-stack magazines, and familiar holster availability make it a strong choice for concealed carry.

Price and Availability

 

S&W 4506

Since production ended years ago, the s&w 4506 is now a used-market item. Prices vary based on condition, but you can expect mid-range pricing—often more affordable than premium 1911s, but higher than budget models.

1911

Prices range widely. You can find reliable budget 1911s, mid-tier models, and extremely high-end custom pistols costing thousands. The 1911 market offers something for every budget.

Which .45 ACP Platform Is Right for You?

Choosing between the s&w 4506 and the 1911 ultimately depends on your shooting priorities.

Choose the S&W 4506 if you want:

  • A rugged, nearly indestructible .45 ACP pistol

  • DA/SA action with a decocker

  • Excellent reliability with minimal tuning

  • A heavy, recoil-taming steel frame

Choose the 1911 if you want:

  • A precision-focused, competition-capable pistol

  • The crispest single-action trigger available

  • Maximum customization and aftermarket support

  • Classic ergonomics and a slimmer profile

Both pistols deliver excellent performance, but their personalities differ dramatically. The 4506 is a modern-era workhorse, while the 1911 is a timeless precision machine.

Final Thoughts

Sell guns debates like this are common among .45 ACP lovers, but the truth is that both the s&w 4506 and the 1911 have earned their reputations honestly. Whether you’re drawn to the brute strength and reliability of the 4506 or the refined elegance and precision of the 1911, you’ll end up with a firearm that has stood the test of time. Your choice ultimately comes down to how you shoot, what you value, and which platform gives you the confidence and comfort you need.
