How We Tested the Best Suppressor-Ready Handguns

To identify the best suppressor-ready handguns, a systematic and thorough testing process was essential. In this section, we’ll walk you through the methodology used to evaluate these firearms, ensuring accuracy, reliability, and performance. Each handgun was tested for its suppressor compatibility under real-world conditions to ensure it meets the needs of both tactical and recreational shooters.

Evaluation Criteria

1. A suppressor-ready handgun must feature a threaded barrel to attach a suppressor effectively.
2. We verified that all barrels had standard threading (e.g., ½”-28 or M13.5×1 LH) for compatibility with common suppressors on the market.
3. Taller sights are crucial for proper target acquisition when using a suppressor, as they allow shooters to see over the suppressor body.
4. Handguns with factory-installed or optional raised sights scored higher in this category.
5. Firearms were tested for cycling reliability with a variety of popular suppressors attached, such as those from brands like Dead Air, SilencerCo, and SureFire.
6. Malfunctions such as failure to eject (FTE) or feed (FTF) were carefully noted during testing.
7. We evaluated group sizes at various distances (10-25 yards) both with and without the suppressors attached to assess whether performance was impacted when suppressed.
8. Durability of materials such as barrels, frames, and slides was reviewed since some firearms are subjected to extra stress when suppressed.
9. Corrosion resistance was also evaluated given that suppressed firearms often accumulate more fouling due to trapped gases.
10. Handgun controls—such as slide stops, magazine releases, and safeties—were assessed for usability even with gloves or during tactical training scenarios.
11. Balance and handling were also analyzed since attaching a suppressor can alter the weight distribution of a firearm significantly.

What Makes a Gun Suppressor-Ready

When evaluating whether a handgun is suppressor-ready, there are key features and design elements that set it apart from standard models. These features ensure compatibility with suppressors while maintaining performance, accuracy, and safety. Here’s an in-depth look at what defines a suppressor-ready firearm.

Threaded Barrel

• Thread Pitch: Different suppressors require specific thread pitches (e.g., 1/2×28 for most 9mm handguns). Ensuring compatibility between the gun’s threading and your chosen suppressor is essential.
• Barrel Length: Suppressors add length to your firearm, so a slightly longer barrel can help balance this extension without compromising usability.

Elevated Sights

• Co-Witness Capability: These sights allow you to align them over the top of the suppressor for an unobstructed view.
• Night Sights Option: Many manufacturers integrate night sights into elevated configurations for low-light use.

Optics Compatibility

Modern shooting preferences often favor red-dot optics for enhanced accuracy and quick target acquisition. Many suppressor-ready pistols are designed with optics-cut slides or compatibility plates, providing flexibility for users who want both suppressed performance and advanced sighting systems.

Recoil Spring Adjustments

• Reduced Recoil Spring Tension: Helps maintain reliable cycling with subsonic ammunition commonly used with suppressors.
• Dual-Spring Systems: Some models incorporate advanced dual-spring setups designed specifically for suppressed operation.

Suppressor-Friendly Ammunition Compatibility

A truly effective suppressor-ready handgun should function flawlessly with subsonic ammunition to maximize sound suppression. Subsonic rounds typically travel below the speed of sound (less than 1,100 feet per second), reducing noise caused by supersonic cracks during firing.

Factor	Subsonic Ammunition Impact
Noise Reduction	Minimizes report noise significantly
Cycling Reliability	Works best when paired with tuned springs
Compatibility Issues	Ensure chambering supports subsonic loads

Additional Features

• Thread Protectors: Prevent damage to threads when not using a suppressor.
• Barrel Coatings: Durable finishes like nitride or stainless steel improve resistance against wear caused by frequent attachment/detachment.
• Pre-Fitted Adapters: Certain brands include adapters out of the box, saving users extra steps during setup.

By understanding these features and looking for them in your next purchase or upgrade, you can ensure seamless integration between your firearm and its attached silencer system—enhancing both performance and practicality in any shooting scenario.

Make Your Current Gun Suppressor-Ready

1. Check Barrel Compatibility

The most crucial component of making your gun suppressor-ready is the barrel. Suppressors attach directly to your firearm’s barrel, so it must have the proper threads to secure the suppressor.

• Threaded Barrel: If your handgun doesn’t already have a threaded barrel, you will need one. Many manufacturers offer aftermarket barrels for popular pistol models like Glock, Smith & Wesson M&P, and SIG Sauer P320.
• Thread Pitch: Ensure that the thread pitch on your new barrel matches the suppressor you intend to use (e.g., 1/2×28 is common for many handguns). Mismatched threads won’t allow proper attachment.
• Barrel Length: A longer threaded barrel might be necessary for optimal suppressor performance since it ensures stability during firing.

2. Optimize for Suppressor Height Sights

Adding a suppressor can interfere with standard handgun sights by blocking visibility of the sight picture. Address this issue by installing taller sights designed specifically for use with suppressed firearms.

• Suppressor Height Sights: These taller sights rise above the body of most suppressors, allowing you to aim accurately without obstruction.
• Night Sights: Consider night sights or fiber-optic options for low-light conditions when using your gun with a suppressor.

3. Upgrade Your Ammunition

Suppressors work best with subsonic ammunition because it reduces noise levels by keeping bullet speeds below the sound barrier.

• Subsonic Rounds: Opting for subsonic ammo ensures quieter operation while still delivering sufficient stopping power.
• Caliber-Specific Options: Popular calibers like 9mm and .45 ACP often have readily available subsonic loads.

Caliber	Common Subsonic Grain Weights	Typical Usage
9mm	147 gr	General purpose
.45 ACP	230 gr	Low recoil and quiet shooting

4. Consider Thread Protectors

When upgrading to a threaded barrel, you’ll likely want a thread protector for occasions when you’re not using a suppressor. These protectors prevent damage to the threads on your barrel during regular use or storage.

5. Recoil Spring Adjustment

• Heavier Recoil Spring: Installing an upgraded recoil spring can help manage increased back-pressure caused by suppressed firing.
• Tuning Kits: Some manufacturers offer spring kits that allow adjustments based on ammunition type and suppressor design.

When Professional Help is Necessary

• Fitting threaded barrels into complex models.
• Ensuring proper alignment between the barrel threads and suppressor.

Always verify local laws before modifying any firearm or purchasing accessories such as threaded barrels or suppressors. Legal restrictions vary widely based on location.

By tailoring these upgrades carefully, you can transform your existing handgun into a reliable and effective tool for suppressed shooting without needing an entirely new firearm investment.

Make Your Current Gun Suppressor-Ready

If you already own a handgun and don’t want to invest in a new suppressor-ready pistol, there are ways you can modify your current firearm to support a suppressor. With the right upgrades and modifications, you can enjoy the benefits of suppressed shooting without having to replace your existing equipment. Below is a guide on how to make your current gun suppressor-ready.

1. Threaded Barrel Installation

Most handguns are not manufactured with threaded barrels, which are essential for attaching a suppressor. To make your firearm suppressor-compatible:
– Purchase a threaded barrel: Check if your handgun model has aftermarket threaded barrels available from reputable manufacturers like SilencerCo or StormLake. Ensure that the thread pitch matches the suppressor you plan to use.
– Install it professionally: While some shooters may be comfortable swapping barrels themselves, it’s often best to have a gunsmith handle the installation to ensure proper alignment and functionality.

2. Suppressor Height Sights

When using a suppressor, standard sights may become obstructed by the device itself, limiting your ability to aim effectively. To address this issue:
– Install suppressor height sights: These higher-profile sights allow you to see over the suppressor and maintain target acquisition. Many manufacturers, such as Trijicon and AmeriGlo, offer compatible options for various handgun models. – Consider optics compatibility: Alternatively, some shooters prefer installing red dot optics on their pistols for enhanced accuracy when paired with suppressed setups.

3. Recoil Spring Adjustment

Adding a suppressor can affect the recoil dynamics of your firearm due to increased weight at the muzzle end. To ensure reliable performance:
– Upgrade or modify your recoil spring: Heavier or lighter recoil springs may be required depending on how your gun cycles with a suppressor attached. – Test extensively after adjustments: Visit the range after making changes to confirm proper cycling and functionality under suppressed conditions.

4. Thread Protectors for Versatility

If you’re equipping your firearm with a threaded barrel but won’t always use it with a suppressor:
– Use thread protectors: These small caps screw onto exposed threads when not using a suppressor, preventing damage and debris buildup.

Feature	Recommended Brands/Options
Threaded Barrels	SilencerCo, Agency Arms
Suppressor Height Sights	Trijicon HD XR Night Sights
Recoil Spring Kits	Wolff Gunsprings
