Suppress your PDW
The Flux Raider is one of the most innovative PDW (Personal Defense Weapon) platforms currently available. The Flux Raider is engineered to be compatible with the Sig Sauer P320 series, including popular models such as the M17, M18, full-size, compact, X-Five, X-Five Legion, VTAC, and TacOps variants. Additionally, the Raider 365 chassis is specifically designed to accommodate the Sig Sauer P365 platform.
However, while you can equip some attachments pretty easily such as red dots and lasers, one major challenge many users face is finding a suppressor that works well with the Flux Raider. Due to its compact design, short barrel length, and sensitivity to recoil timing, not all suppressors pair well with this platform. Many cause excessive backpressure, cycling issues, or interfere with the brace or accessory rails.
After extensive testing, the team at Guerrilla Tactical has identified two suppressors that consistently deliver reliable performance on the Flux Raider, and we are going to break it down.
Why Suppressing the Flux Raider Is Complicated

Suppressing a handgun-based PDW like the Flux Raider is not as simple as threading on a can. Several unique factors complicate the process:
- Limited Muzzle Clearance: The Raider鈥檚 folding brace and rail-mounted accessories can make it difficult to accommodate longer or wider suppressors.
- Short Barrel Dynamics: With minimal dwell time, a suppressor must be efficient without disrupting the cycling process.
- Backpressure Sensitivity: The Raider, built on the P320 platform, can experience failures if a suppressor adds too much backpressure to the system.
Because of these factors, users must be selective about their suppressor choice. Not every 9mm suppressor will work properly, and some may even compromise the function or safety of the system.
SilencerCo Spectre 9: Compact, Lightweight, and Purpose-Built
The SilencerCo Spectre 9 was designed with compact PDW systems in mind. With its small size and low weight, it鈥檚 an excellent match for platforms like the Flux Raider, where every inch and ounce counts.
Key Specifications:
- Caliber: 9mm (also rated for subsonic .300 Blackout)
- Length: 4.75 inches
- Weight: 4.9 ounces
- Mounting: Direct thread or piston system (1/2×28)
- Construction: Aluminum and stainless steel
- Finish: Black Cerakote
Performance with the Flux Raider:
In Guerrilla Tactical鈥檚 testing, the Spectre 9 functioned great when paired with the Flux Raider builds. It maintained consistent cycling, produced minimal gas blowback, and preserved the Raider鈥檚 compact form factor. The suppressor鈥檚 lightweight design avoids front-end drag, while the short length ensures it doesn鈥檛 interfere with the folding brace or rail accessories.
For users who prioritize mobility and reliability in a compact PDW setup, the Spectre 9 is a top-tier option.
Rugged Obsidian 9: Versatility with Proven Reliability
The Rugged Obsidian 9, available via Silencer Shop, is a modular suppressor known for its durability and adaptability. While it is larger and heavier than the Spectre 9, it offers modularity that can be a major advantage for users running multiple hosts.
Key Specifications:
- Caliber: 9mm (rated for subsonic .300 Blackout)
- Length: 7.8 inches (full size), 4.8 inches (short configuration)
- Weight: 12.7 oz (full) / 8.7 oz (short)
- Mounting: Booster, direct thread, or 3-lug
- Construction: 17-4 stainless steel and aluminum
- Finish: Type III hard coat anodized
Performance with the Flux Raider:
In its short configuration, the Obsidian 9 performed reliably on the Flux Raider platform. Guerrilla Tactical reported smooth cycling, good sound suppression, and minimal gas blowback. The added versatility of being able to switch between full and short lengths allows users to tailor their setup for different roles鈥攚hether that鈥檚 maximum suppression or minimal footprint.
The suppressor鈥檚 durable materials and easy disassembly also make it a great option for high-volume shooters who want something that can handle more abuse without sacrificing compatibility.

Use Cases for a Suppressed Flux Raider
Running a suppressor on the Flux Raider platform expands its capabilities in several key scenarios:
- Truck Gun Builds: A suppressed PDW like the Raider is ideal for keeping in your vehicle鈥攃ompact, quick to deploy, and reduced in noise signature.
- Go-Bag Weapons: Suppressors like the Spectre 9 or Obsidian 9 (short) maintain a small profile, allowing the Raider to fit into compact packs.
- Home Defense: A suppressed Raider minimizes hearing damage risk in confined spaces while offering enhanced controllability and faster follow-up shots.
- Training and Range Use: Lower recoil, reduced noise, and improved shooting comfort make a suppressed Raider enjoyable and effective on the range.
Final Thoughts: Suppressors That Actually Work on the Flux Raider

Suppressing the Flux Raider used to involve a lot of trial and error. Many suppressors interfered with the brace, disrupted the recoil system, or added too much weight to a compact build. Thanks to thorough testing by Guerrilla Tactical, there are now two verified options for shooters looking to suppress their Raider without compromising performance:
- The SilencerCo Spectre 9 is the best choice for those who need an ultra-light, compact suppressor that fits seamlessly into the PDW role.
- The Rugged Obsidian 9, especially in its short configuration, offers added versatility and ruggedness for users who want multi-host compatibility without sacrificing reliability on the Raider.
For anyone looking to build a suppressed Flux Raider PDW, these are the silencers that work鈥攁nd they鈥檝e been tested under real-world conditions to prove it.
