Description

Take your training to new levels of competency with the SIG Sauer P320 Spectre Comp Blackout Pellet Air Pistol. Powered by an in-magazine CO2 cartridge, it offers realistic blowback and correct ergonomics. The reciprocating slide is made of metal to offer a convincing heft that enhances realism. It launches .177-caliber pellets from the rifled barrel at up to 340 FPS and is fed by a 20-round, drop-free magazine. 

Aiding in quick mag swaps, the textured X-Series Grip Module has a flared magazine well. Changing the CO2 cartridge is easy thanks to SIG’s patented cam-level CO2 loading system. It has a functional takedown lever and does not require any tools to field strip.

Thanks to the under-barrel Picatinny rail, you can add your choice of accessory, such as a light, to level up your low-light training. This semi-auto air pistol is 8.5” overall, weighs 37 ounces, and has a 4.5lb trigger weight. You can use the iron sights or swap to a red dot optic. It comes with one magazine. 

Ramp up your defensive training, or have some fun plinking at the range. Buy your SIG Sauer P320 Spectre Comp Blackout Pellet Air Pistol from Pyramyd AIR today.

I like pretty much everything. Its well balanced when shooting & the barrel is pretty accurate. I don't know if all of them are like this, but the manual safety doesn't work. Otherwise, it's really good.

Not much, really. Except maybe a safety that actually works. Also, the magazines & the pellet belt inside em are extremely flimsy. I can see em breaking apart easily.

It's a fun shooter, with a nice hefty weight & balance. Very comfortable in hand. It's rather quiet, too. That's like most Co2 pistols. Like I said, I'd like to see a safety that actually works & magazines made of a tougher material. But overall, it's a great Co2 repeater. And the price is right, so go ahead & buy it. If you don't like it, you can send it back for a refund.

It's the same with or without Co2 on the one I received. Safety doesn't work. It will fire with the safety on.

Rodd Apr 22, 2026

There is a possibility that there may be a misunderstanding of how the safety works. Engaging the safety on this model, along with the M17, simply engages a hammer block which prevents the hammer from striking the valve. It does not lock the trigger. If you were simply checking the safety without CO2, the trigger would pull and you'd hear the click of the hammer with the safety on or off so it may seem like it isn't doing its job. However, with CO2 installed you should find that it will not actually fire when the safety lever is engaged.

I like this version of the Sig Sauer P320 better than the original. It fits my hand much better than the regular P320. The takedown feature is great as it allows for barrel cleaning and lubrication with the slide off. The magazine CO2 valving is much easier to use than the turnscrew style; the separate 20 round belt feed is easy to change out and rather inexpensive. The open "ejection port" allows me to use this version as a trainer for new shooters regarding how to apply a cable lock. It also gives them another option to shoot along with my original (and well used) P320. All in all a good purchase for the money, better than the original P320! And I get 80 shots per 12 gm. CO2 cartridge, 20 more than my original P320.

Include a printed instruction manual with the gun. Make a red dot mount for it and the M17; this gun begs for one. Something like the Air Venturi red dot for the SA Hellcat Pro. Maybe include an extra pellet magazine?

Rapid magazine changes are still not a good idea with this gun, the structure of how the pellet magazine sits in the main gas valve "magazine" may be damaged. This is an excellent value at this price point!

Kent Apr 14, 2026

There is a mount for a reflex or holographic site on this Co2 pistol. There's a metal plate on top in front of the fixed rear sight with 2 hex screws. Just unscrew those & use the same 2 screws to mount the optic sight of your choice. I haven't put one on mine yet, but I'm seriously thinking about it. Happy shooting!

Change your advertising to reflect true features of the product

Misrepresented product - 1: Fps nearly 100fps lower on average than advertised according their own 10 for 10 test with projectile matching weight of manufacturer specifications. 2- Advertised as "full blowback" which would suggest blowback action re-cocks the striker allowing the item to work in single action - but in reality it does not - this item works in double action only. Do not know accuracy so left mid star - not motivated to use product now so wont ever know. If they offer to cover return shipping and refund all associated costs I will return it.

The looks, the weight and the 20 round mag. I also like the cam over way to puncture and set the Co2. This is an accurate fun pellet gun to shoot.

Don't much care for the trigger pull as it is always like double action with a long reset. This is louder than all my other o2 guns, but not much can be done about that.

All around good plinker.

It’s a very nice replica. It is pretty much the M1 17 with a comp and black and a better trigger.

Nothing

Buy it it’s definitely worth it

Dallas Apr 09, 2026

Update this thing loves CO2 expect 40 or 50 shots. Good usable shot shots out of a CO2. Give it plenty of time in between shots to warm back up and it is very very accurate. 750 pellets to it.

Blowback, Accuracy open sight shooting was 4 stars, Added a red laser 5 stars, The overall handing of the pistol felt good. I did get the velocity over 340 F P. S.( 370.5) (348.3)

Trigger pull a long first stage. I would of like the slide to lock back at the last shot.

I recommend it should be part of your pistol collection.
