Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol Table Top Review

No Comments

Type: Air Pistol.

Manufacturer: Sig Sauer ASP

Model: Sig Sauer ASP P226.

Materials: Mostly metal build.

Weight: 2.35 pounds (1066 Grams).

Barrel: 4.75 inches - Rifled steel.

Propulsion: 12 gram CO2.

Action: Blowback single and double action.

Ammunition Type: .177 caliber pellets.

Ammunition Capacity: 16 round double sided rotary stick magazine.

Max FPS: Claimed 510 but really more like 400.

Trigger Pull: The trigger pull on the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol is a lot better than I thought it was going to be. The blowback operation does place the hammer in the cocked position for single action type shooting but the the trigger is still required to index or advance the next pellet to line up with the barrel. Because of this, trigger pull is full length even in single action mode but you can barely feel any added friction from the indexing of the rotary magazine. All of this makes for a slightly longer trigger pull but one that is light weight with a fairly nice and easy release.

Accuracy: I have not done my official Field Test Shooting Video with the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol and I am not sure when I am going to get the chance to do so since I am waiting on a replacement Chronograph for my velocity portion of my testing. That said I can say that Sig has already done some of the work for me and conducted their own "real world" velocity testing for their ASP line of CO2 Pellet Guns. Sig tested both a standard 8.18 grain lead pellet and a high velocity 5.25 grain alloy pellet shooting an 8 shot string with each to find out average fps performance for both pellet types. The 8.18 grain lead pellet average 359 fps while the 5.25 grain alloy pellet average 403 fps. In terms of accuracy, I was able to get about a 2 inch 16 shot grouping on two separate 30 foot back tests which is pretty decent. I did notice that when shooting a 16 shot string, the first and last shot velocity will vary a fair amount as the CO2 cools the gun and lowers the fps. I would recommend taking your time in-between reloads to let the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol warm back up.

Build Quality: The Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol is a very solid feeling pistol with its all metal construction. Weighing it at 2.35 pounds, it is actually a tad bit heavier then the real steel version but not by much. Sig claims that their entire APS line of pellet guns is life tested for 15,000 shots so you know this gun is going to last and provide years of shooting fun. The fit and finish seem really good, so far no real paint or finish problems and all mechanically everything is operating as it should.

Realism: The Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol is a very close replica of the real steel Sig Sauer P226, I would say it most closely takes after the MK-25 Threaded Barrel version. I really like the fact that the safety also works as a working decoker just as it would on the real P226. Other similar working parts are the magazine release and the hammer that stays back for true single action shooting. The slide catch release and take down leaver are purely for show but they are not moulded in parts so they look the part. One slight disappointment for me is when a gun does not have a cut out ejection port, that is the case with both the Sig Sauer ASP P226 and P250 but it does not take away from the shooting fun in any way.

  • Good overall replica of the real steel Sig Sauer P250.
  • Really solid feeling gun, has awesome weight to it with it’s all mental construction, pretty close in weight the real steel version.
  • Designed by Sig and made in Japan, fully Sig Sauer licensed.
  • Nice heavy blowback operation.
  • Got respectable accuracy and seemed to shoot pretty hard.
  • Safety works as the de-cocker same as the real Sig Sauer P226.
  • White dot sights and accessory rail.
  • Super easy CO2 loading system, no having to tighten a CO2 tab.
  • Great feel to the trigger not heavy or sticky in any way.


  • Shots tended to slow down a bit near the end of a 16 shot strong as the gun cooled down.
  • Sight are non adjustable.
  • Ejection port is not cut out.


What I really like about the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol is that like all the other APS airguns from Sig, it is a product that Sig has decided to invest a lot of their time and effort to develop rather then simply grab an existing arigun product from a manufacturer and slap their license on it. Sigs product ingenuity is what will help to improve the airgun industry overall. Getting back to the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol, it's a really solid CO2 Pellet pistol that is a lot of fun to shoot and for Sig Sauer P226 owners, the pellet shooting airgun version offers a super economical and safe way to get some practice in using a product that looks, feels and shoots similarly to their real steel counterpart.
