Sig Sauer P250 & P226 - Umarex PX4 Storm - Gamo P25 & MP9 Comparison

Make sure to watch my YouTube video for this Comparison Review as I go into a lot of detail about the similarities and difference with each of these CO2 Blowback Pellet Guns.

Here are some of the main Similarities when comparing the Sig Sauer P250 & P226 - Umarex PX4 Storm - Gamo P25 & MP9:

  • All of these CO2 blowback pellet guns are made for each company in Japan (I am assuming from the same factory?)
  • All of the listed Pellet Airguns shoot .177 caliber pellets (Can be Alloy or Lead)
  • They all have double sided rotary stick magazines that hold 8 rounds on each end for a total of 16 shots per magazine.
  • All of the Airguns use 12 gram CO2.
  • All compared pellet guns have Blowback operation.
  • All of these pellet pistols have single and double action triggers except for the Gamo MP9 which is single action only and needs to be charged on the first shot.
  • They all have rifled barrels.

Here is where we find some key differences between these CO2 Blowback Pellet Pistols:

The FPS Velocity for each Airgun: 

The weight of Each Pellet Gun:

The Barrel Length for each Air Pistol:

The Main Build Materials for each Pellet Pistol:

Is the Ejection Port Cut Out? 

Is it a Replica of a Real Steel Gun? 


Sig Sauer ASP P250 CO2 Blowback .177 Caliber Pellet Pistol Table Top Review

Type: Air Pistol.
Manufacturer: Sig Sauer ASP
Model: Sig Sauer ASP P250.
Materials: Metal and plastic build.
Weight: 1.45 pounds (658 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 500 but really more like 400.

Trigger Pull: The trigger pull on the Sig Sauer ASP P250 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. For some reason the Sig Sauer P226 trigger does feel a little smoother with a slightly easier release.

Accuracy: I have not done my official Field Test Shooting Video with the Sig Sauer ASP P250 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 353 fps while the 5.25 grain alloy pellet average 399 fps. In terms of accuracy, I was able to get just under a 2 inch 16 shot well centered 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 P250 CO2 Blowback .177 Caliber Pellet Pistol warm back up.

Build Quality: The Sig Sauer ASP P250 CO2 Blowback .177 Caliber Pellet Pistol is a bit on the lighter side coming in around 1.5 pounds since it does incorporate both metal and plastic construction. You will find the Sig Sauer P250 has a metal slide and plastic frames similar to the real steel version. Weighing it at 1.45 pounds, the P250 is lighter then a standard Sig Sauer P250. 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 P250 CO2 Blowback .177 Caliber Pellet Pistol is a very close replica of the real steel Sig Sauer P250. I really like the fact that the safety also works as a working decoker just as it would on the real Sig P250. 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 good and realistic. 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.
  • Designed by Sig and made in Japan, fully Sig Sauer licensed.
  • Nice heavy blowback operation.
  • It might feel a bit light weight at first but out of the two Sig Sauer ASP pellet pistols this one seems to shoot a bit better.
  • Got respectable accuracy and seemed to shoot pretty hard.
  • Safety works as the de-cocker same as the real Sig Sauer P250.
  • White dot sights and accessory rail.
  • 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 P250 CO2 Blowback .177 Caliber Pellet Pistol is that like all the other APS Airgun 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 Airgun 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 P250 CO2 Blowback .177 Caliber Pellet Pistol, it may feel a bit light weight at first but the heavy blowback will rock you unexpectedly! I found in terms of comparison to the Sig Sauer ASP P226, the P250 was more accurate and well centered on target for me as well. If you're a Sig Sauer P250 owner you are for sure going to want to pick yourself up one of these ASP CO2 Blowback Airgun versions so you can get some extra practice time in for pennies per shot and the ability to shoot in a lot more locations..

Sig Sauer P226 and P250 CO2 Blowback .177 Caliber Pellet Pistol Preview

I have been waiting a long time (since SHOT Show two years ago) to finally get my hands on the Sig Sauer ASP CO2 Blowback Pellet Pistols and they finally arrived at my US Post Office Box. A big thanks to Sig for sending them to me! So today I made the dreaded trip across the boarder to pick them up and then deal with the Border Custom Agents which much of the time have no idea what they are doing when it comes to Airgun Importation laws. It's not like it's their job or anything??? Today was no exception and I spent several hours waiting as my Customs Agent disappeared behind closed doors to do his research on Airgun Importation. That's another story completely that at this time I don't want to get into, perhaps I will make a video about this another time? The good news is I prevailed and was able to bring both of my new Sig Sauer Air Pistols home with me.

This video is a bit like an unboxing and preview video combined, I don't go into a lot of detail or talk specifications much but I do show you around both the Sig Sauer ASP P226 and Sig Sauer ASP P250 nice and close and in detail. I will be making a future Table Top and Shooting Video for these fine Sig Air Pistols which are both CO2 operated, have blowback operation, shoot in both single and double action, shoot lead or alloy pellets using a 16 round double sided rotary stick styled magazine, shoot around 400 fps and feature Sig Sauer licensing all around.

SHOT Show 2016 - Sig Sauer Interview

In this 2016 SHOT Show Interview I talk with Dani Navickas from the Airgun division of Sig Sauer. Dani and I discuss Sig's new line of CO2 Blowback Pellet rifles and pistols. Dani talks about some of the behind the scenes information that went into the development and manufacturing of Sig's new line of CO2 Airguns.

Sig CO2 P226 and P250 Air Pistols along with their Sig MPX and MCX Air Rifles have been developed in house by Sig.Sig has been working very closely with a Japanese manufacturer to make sure that every stage of development is to Sig's high standards. The new Sig CO2 Blowback rifles and pistols are made to match the real steal version in almost every way including dimension, weight, functionality, materials used and even trigger pull.

Sig's new Sig MPX and Sig MCX Pellet Rifles have a brand new patented belt fed 30 round pellet magazine that is indexed via the internal blowback action of these rifles smoothing out the trigger action. The Sig P226 and Sig P250 pistols use a double ended 16 round pellet magazine similar to what you would find on Umarex's PX4 Strom blowback pellet pistol.

Look for Sig's new line of CO2 Blowback Pellet Airguns coming out shortly.
