Sig Sauer P320 Spectre Comp "Blackout" CO2 Blowback Pellet Air Pistol
The SIG AIR P320 Spectre Comp Blackout is what happens when somebody takes the already popular P320 platform and decides the normal version simply wasn’t dramatic enough. Styled after the firearm Spectre Comp series, this .177 pellet-firing CO2 pistol combines proper replica weight and handling with a far more usable shooting system than most blowback BB pistols.
This is not just another generic polymer replica pretending to be tactical because somebody added slide cuts and a flat trigger. The Spectre Comp actually feels substantial in the hand thanks to its full metal slide, aggressive X-Series grip module, and realistic proportions. At just over 1kg, it has enough heft to feel convincing without becoming cumbersome.
The overall look is unapologetically modern. The compensated slide design, flared magwell, deep slide serrations, and textured grip all lean heavily into competition pistol styling, but unlike many “race gun” style replicas, this one still feels practical rather than cartoonish.
What makes the P320 Spectre Comp particularly interesting is that it shoots pellets rather than steel BBs. That means you get a rifled barrel and noticeably better accuracy potential than most blowback replicas, while still retaining realistic magazine handling and recoil operation.
The 20-round Rapid Pellet Magazine system is one of the better modern CO2 magazine setups currently available. The entire drop-out magazine houses both the pellet system and the CO2 capsule, allowing spare magazines to be pre-loaded and ready to go rather than constantly stopping to reload fiddly rotary systems. The built-in cam lever piercing system also means CO2 changes require no tools whatsoever, which immediately makes ownership less irritating than half the market already.
The blowback action gives a satisfying amount of recoil impulse without becoming wasteful or sluggish, and the pistol cycles quickly enough to stay entertaining while still maintaining respectable consistency. The trigger system indexes the magazine during the pull, which is how SIG manages to make a semi-auto pellet system function reliably in this format.
In practical terms, this sits in a very nice middle ground.
Most pellet pistols tend to look either aggressively German or like they escaped from a 1997 shooting club cupboard. Most replica pistols meanwhile prioritise realism but sacrifice accuracy entirely by using smoothbore BB systems.
The Spectre Comp Blackout manages to bridge both worlds surprisingly well. You get a pistol that looks and handles like a modern firearm replica while still being genuinely enjoyable for proper target shooting rather than just emptying CO2 capsules at cans for 10 minutes before getting bored.
The Picatinny accessory rail underneath also gives plenty of room for torches or lasers if that’s your thing, although realistically the appeal of this pistol is the platform itself rather than turning it into a science project covered in accessories.

A few things are worth knowing before buying, particularly as no physical manual is included with the pistol and some important details are only covered in the online documentation.
The trigger requires a full deliberate pull each shot as it rotates and indexes the pellet system before firing. Half-pulls or trying to “ride” the trigger like a firearm reset can cause failed indexing or jams. Once you understand how the system works, it becomes second nature, but this is definitely a pellet system first and foremost rather than a true firearm-style trigger.
It is also important to note that the top optic plate screws are decorative only and should not be removed. The pistol visually resembles an optics-ready setup, but UK mounting support for the SIG AIR plate system is currently limited. Realistically, this pistol is best bought as a complete standalone platform rather than as a base for endless upgrades.
And honestly, that’s perfectly fine.
The real strength of the P320 Spectre Comp Blackout is that it already succeeds at what it is supposed to be: a respectable, accurate, modern-looking pellet shooting pistol replica that feels far more premium than most CO2 handguns currently on the market.
