Sig Sauer MPX ASP .177 Caliber Pellet Rifle Field Test Review

I have already made a couple of videos for the Sig Sauer MPX ASP .177 Caliber Pellet Rifle, my official Table Top Review and a Preview Video where I shoot some rounds at a Sig Sauer Quad Shooting Gallery.

In this Review Video I focus on the shooting performance of the Sig Sauer MPX ASP .177 Caliber Pellet Rifle to find out what kind of FPS we can get out of it and exactly how accurate the MPX is from 30 feet back using a fairly stable semi rested shooting position. I'll tell you right away my Chrony Chronograph has officially called it quits and I will be looking at replacing it for future Field Test Shooting videos. Lucky for us Sig sent me their real world inhouse testing using both 5.25 grain high velocity pellets and standard 8.18 grain lead pellets.

Here are the average results Sig achieved from each pellet type shooting an 8 shot string.

5.25 Grain Alloy High Velocity Pellets:

  • FPS - 506
  • Energy in Foot pounds - 2.98
  • Energy in Joules - .1257
  • Temperature at time of testing - 71 Degrees Fahrenheit 

8.18 Grain Standard Lead Lead Pellets:

  • FPS - 447
  • Energy in Foot pounds - 3.63
  • Energy in Joules - .153
  • Temperature at time of testing - 71.5 Degrees Fahrenheit

In terms of accuracy, this rifle is made to shoot at much further out ranges than 30 feet but I was still able to get on what kind of a grouping is possible with the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I first shot 10 rounds at my paper target and then had a quick look. I was able to get a nice 1 inch grouping which I am sure I could improve upon with some more shooting time with the rifle. I was also not using a magnified scope, just a standard red dot. I then shot the remaining 20 rounds to finish off the 30 round belt fed magazine and for the most part the majority of the pellets all fell within the first 10 shot grouping and I did rip these shots off pretty quickly, about as fast as I could pull the trigger that is.

All in all the Sig Sauer MPX ASP .177 Caliber Pellet Rifle is a good performer, I am very happy with FPS form an 8 grain pellet consistently hitting 450 FPS, that's plenty fast enough to shoot all kinds of targets even out at further ranges. Accuracy was also consistent even under rushed shooting so I can imagine the Sig Sauer MPX ASP .177 Caliber Pellet Rifle would make a great trainer for tactical shooting situations. I thing Sig has a real winner here, great looks, excellent quality and good performance all at a reasonable cost. I just hope we get them here in Canada soon...


Update Video - Fitness Contest Again - Sig Pistols on Way - Shooting Videos

I wanted to make a quick update video to let everyone know what I will be up to over the next few weeks since it will effect my video production just a little bit, that said I will do my best to keep the videos coming...

If you remember last year around August, I entered a Fitness contest where I competed in Men's Physique. Well I did fairly well and placed 1st in two divisions, Masters and Open. What this means is I am now qualified to compete in my local Provincial Finals this year which is coming up in less than two weeks. The event is called the Vancouver Pro Am and it will be held in Vancouver BC Canada.

To get to the point, my contest prep especially the last couple of week is fairly taxing on me physically and mentally, it also takes up some of my time. So my videos may not be as regular and they may not be as put together since my mind is not working 100% right now due to the lack of food and carbs I am not eating ;) Anyway I will do my best! You can follow my Fitness journey over at

I also talk about two new Sig products I will be picking up next week to review, the Sig Sauer P250 and Sig Sauer P226 CO2 Blowback Pellet Pistols. I hope to at least have a preview video for you later on next week.

Lastly I am working on a couple of Field Test Shooting videos that I have needed to pump out, one is for the ISSC M22 CO2 Blowback BB Pistol and the other is for the Sig Sauer MPX .177 Caliber Pellet Rifle.

Stay posted for all of these upcoming videos...


Sig Sauer MPX ASP .177 Caliber Pellet Rifle Table Top Review

Type: Pellet Rifle.
Manufacturer: Sig Sauer ASP
Model: Sig Sauer MPX ASP
Materials: Metal and Nylon Fiber build.
Weight: 7 Pounds (3300 Grams).
Barrel: 8 inch steel rifled.
Propulsion: 88 or 90 Gram CO2.
Action: Semi Auto, double action only.
Ammunition Type: .177 caliber pellets.
Ammunition Capacity: 30 rounds belt fed.
FPS: Up to 600 fps (When shot by a Unicorn)

Trigger Pull: The trigger pull on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle is actually pretty decent when you consider the first part of the trigger pull is used to advance the belt fed 30 round magazine. One would think that there would be a lot of added friction from the belt but this does not seem to be the case. There is some internal blowback action going on but it is only used to cock the internal hammer/striker which does lesson the overall amount of trigger pull required. The trigger pull is shorter than expected with all that is going on and it's not overly heavy so quick and predictable action shooting is very possible with the Sig Sauer MPX ASP .177 Caliber Pellet Rifle.

Accuracy: So far I have not done my official Field Test Shooting Video for the  MPX ASP .177 Caliber Pellet Rifle but I did have the chance to get out and shoot some rounds down range at my Sig provided Quad Shooting Gallery that I had setup about 35-40 feet away. Even though I did not have my red dot all perfectly sighted in I was still able to hit the smallish metal targets fairly well using the Sig Sauer MPX ASP. In terms of velocity you can expect from the Sig Sauer MPX ASP .177 Caliber Pellet Rifle, 600 fps is a bit optimistic. Sig did send me a real world fps performance spread sheet they had conducted using both 5.25 grain alloy pellets and 8.18 grain lead pellets shooting 8 rounds and averaging out the fps. The 5.25 grain pellets averaged in at just over 500 fps while the heavier 8.18 grain pellets came in with an average of just under 450 fps. Pretty much what I would expect from a shorter barreled CO2 rifle.

Build Quality: The build quality for Sig Sauer MPX ASP .177 Caliber Pellet Rifle is excellent, you can tell Sig Sauer had a lot of hands on in the design and production of this Pellet Shooting Air Rifle! The materials used and fit and finish are top notch and the mechanical function again is really good, I am kind of amazed at how well their belt fed rotary magazine design works in terms of feeding and operation. So far I have not experienced any pellet feeding problems at all using both lead and alloy flathead pellets.

Realism: The Sig Sauer MPX ASP .177 Caliber Pellet Rifle is for the most part designed to be used as a side by side optional training aid for the real steel Sig Sauer MPX Rifle. Sig wanted the pellet version to look and feel as close as posable and Sig has done a good job with this. Other than the lessor recoil and noise factor, the Sig Sauer MPX ASP .177 Caliber Pellet Rifle works and shoots much the same as a real steel Sig Sauer MPX Rifle.


  • Has to be the best semi auto pellet rifle replica I have seen and shot to date.
  • Near perfect replica of the real steel Sig Sauer MPX including licensing and trademarks.
  • Awesome build quality, lots of metal parts and the nylon parts are true to form and very solid.
  • Rifle has been tested to shoot over 15,000 rounds reliably.
  • 30 round full size belt fed magazine has super high capacity and works flawlessly.
  • Decent fps performance, about what I would expect from a multi-shot CO2pellet shooter and totally usable.
  • Trigger feels really good, not too long or to heavy and very consistent feel on every shot.
  • Fully adjustable pop up front and rear sights.
  • Lots of rails for your pick of sight options and other add on accessories.
  • Very accurate with it’s 8 inch rifled barrel.


  • Rear stock is none adjustable so the gun may feel kind of cramped for larger shooters.
  • Internal blowback action does not advance the belt fed magazine but does cock the internal hammer.
  • FPS claim of 600 fps seems a bit optimistic compared to real world testing.

I have been waiting to get my hands on the Sig Sauer MPX ASP .177 Caliber Pellet Rifle for some time now and the wait has been worth it for sure. There are really no other guns out there right now other than perhaps the Umarex CX4 Storm that compare to the Sig Sauer MPX ASP .177 Caliber Pellet Rifle and even so I feel the Sig Sauer MPX is by far the better of the two CO2 Air Rifles. OK so the MPX does not really come close to hitting 600 fps but did you really believe that in the first place? Still consistent 450 fps from a decent grain lead pellet is about what you would expect from a short barreled CO2 rifle. If you do want more fps then look at the MCX with over double the barrel length of the MPX, this will easily get you an additional 100+fps for those of you who thrive on velocity performance. I am fine with 450-500 fps since this is all that is needed to accuracy shoot and nock over most targets at a variety of ranges.

Sig Sauer MPX ASP .177 Caliber Pellet Rifle Preview

I was excited when I first heard that Sig Sauer was coming out with their own line of pellet shooting airguns and that was about 2 years ago! So it's been a long time coming for me to finally get my hands on one of Sigs own in-house Airguns. Sig Sauer was kind enough to send me three of their ASP (Advanced Sport Pellet) airguns, one of which arrived last week, the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I will also be receiving Sigs P250 and P226 CO2 Blowback Pellet Pistols for review when they are sent to me hopefully soon.

I will be performing my standard Table Top and Field Test Shooting videos for all of the Sig Sauer Airguns being sent to me but wanted to get out this preview video for the Sig Sauer MPX ASP .177 Caliber Pellet Rifle to give you a little info on it right away and also let you know what's coming up in terms of Sig Sauer product reviews.

In this preview video I do a little bit of fun backyard shooting simply because I could not resist having a go with this awesome air rifle any longer and needed to shoot it. I was not disappointed! Every pellet I placed in the 30 round belt fed magazine fired flawlessly from the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I used both Sigs high velocity 5.25 grain alloy pellets and some flathead 7 grain RWS lead pellets and all my ammo shot well in the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. I have not done a Chronograph test so far for the Sig MPX but can say the pellets where getting to my Sig Sauer Quad Shooting Gallery Target in no time and I had placed a good 35-40 feet away. Once I figured out my sights I was able to continently hit what looked like pretty small targets from where I was standing, this was no surprise since the Sig Sauer MPX ASP .177 Caliber Pellet Riflehas an 8 inch rifled barrel.

Sig has done some real world pellet fps testing on their own using both light weight 5.25 grain pellets and heavier 8.18 grain pellets and the numbers for an 8 shot average came in at around 505 fps using 5.25 grain pellets and around 450 fps using 8.18 grain pellets. That's plenty enough power to rip into your targets setup even further down range.

My Sig Sauer MPX ASP .177 Caliber Pellet Rifle is the open sight only version but you can get one already paired with Sigs Red Dot system or add your own sighting system, since there are plenty of rails to add just about any kind of accessory to the Sig Sauer MPX ASP .177 Caliber Pellet Rifle.

Check back shortly for my office Table Top and Field Test Shooting videos for the Sig Sauer MPX ASP .177 Caliber Pellet Rifle. And when I do finally get the Sis Sauer p250 adn P226 ASP Air Pistols I will have review videos out for them too.

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.
