First Look & Overview
In this table top review, taking a detailed look at the Sig Sauer P320 Spectre Comp CO2 Blowback Pellet Pistol, a modern, competition-style airgun replica that closely mirrors its real steel counterpart. This model stands out with its aggressive styling, compensated muzzle, and optics-ready slide, making it one of the more premium-looking pellet pistols currently available.
This is a pellet-only airgun with blowback action, designed more for realism and handling than raw velocity. If already familiar with the Sig Sauer M17 pellet pistol, this one shares a lot of mechanical similarities, including the magazine system.

Build Quality & Design
The Sig Sauer P320 Spectre Comp CO2 Blowback Pellet Pistol delivers a solid mix of metal and polymer construction. The metal slide gives it realistic weight and feel, while the polymer frame helps keep things balanced. At around 2.3 pounds, it has a substantial presence in hand without feeling overly heavy.
The grip features enhanced texturing along with a flared magwell, adding to both aesthetics and usability. The slide includes light porting and is optics-ready, allowing for easy installation of a SIG Air RMR red dot.
One standout visual element is the compensated muzzle, which adds to the competition-style look. However, it also impacts field stripping, you’ll need to remove it to fully disassemble the slide.
Magazine & CO2 System
This pistol uses a 20-round belt-fed rotary magazine, which is housed within a drop-out mag body. Loading is straightforward:
Remove the rotary belt insert
Load pellets into each chamber
Reinsert into the mag
CO2 is loaded using a tool-free cam lever system, which is fast and convenient compared to traditional screw-in designs.
Important note: the magazine needs to be firmly seated. A light insertion may not lock it properly, and due to the weight, it could fall out if not fully engaged.
Also worth noting, while the outer mag housing has some polymer components, the internal structure is mostly metal. Still, avoid dropping it on hard surfaces.
Handling & Controls
Ambidextrous safety works from both sides, though visual indicators are only clearly marked on one side
Trigger feels closer to double-action due to the rotary magazine indexing
Slide cycles with blowback but does not lock back when empty
Takedown lever is present, but full disassembly is limited by the compensator
The trigger has a solid feel and requires deliberate pull due to the indexing mechanism. This is normal for belt-fed pellet systems.
Sights & Optics
The pistol comes with fixed white dot sights, which are effective for quick target acquisition. However, they are not adjustable.
For those wanting more precision, the pistol supports SIG Air RMR optics, replacing the rear sight with an included plate.
Performance Expectations
The claimed velocity is 340 FPS, which is typical for blowback pellet pistols. Expect slightly lower speeds with lead pellets (recommended) compared to alloy pellets.
Blowback operation will also consume more CO2 than non-blowback models, trading efficiency for realism.
If looking for a performance reference, similar results can be expected to the Sig Sauer M17 pellet pistol due to shared internals.
Pros
Excellent replica accuracy of the P320 Spectre Comp
Realistic blowback with metal slide
Good weight and balance (~2.3 lbs)
20-round high-capacity pellet magazine
Tool-free CO2 cam lever system
Rifled barrel optimized for pellet shooting
Optics-ready (SIG Air RMR compatible)
Flared magwell and enhanced grip texture
Picatinny rail for accessories
Magazine compatibility with M17
Cons
Lower FPS compared to non-blowback pellet pistols
Higher CO2 consumption due to blowback
Fixed (non-adjustable) sights
Pellet-only (no BB capability, though this protects rifling)
Slide does not lock back when empty
Field stripping requires compensator removal
Final Thoughts
The Sig Sauer P320 Spectre Comp pellet pistol is a strong option for anyone prioritizing realism, handling, and modern styling over raw power. It delivers a premium look with solid functionality, especially for training, backyard shooting, or collectors wanting a high-end replica.
While not the most powerful pellet pistol available, it excels in design, usability, and realism, especially if already a fan of the P320 platform.
For those in Canada, availability may already be live, with US availability likely to follow.
