[SHOT 2016] SIG USA Airguns

While everyone was focusing on the SIG MPX, MCX, and the Legion handguns at the SIG booth, the company had a whole section of new airguns that they are producing. Not airsoft like a number of companies add their name to, but actual .177 caliber CO2 powered airguns. Currently they were offering the P226 Navy, P250, MPX SBR, and an MPX with a faux suppressor as patterns for the airguns. All are offered in various configurations of Flat Dark Earth, Green, and Black. The important thing to note about these airguns is that they are 1:1 replicas. Thus, for training value, their airgun 226s and 250s will take current lights, holsters, and many other accessories that will fit to the actual firearms that they are imitating. All are made from aluminum, but what I found most interesting was the way that SIG configured the CO2 cartridges and the magazine feeds. The MPX versions have the CO2 cartridge hidden in the tubular stock, while the handgun versions have them hidden in the rear portion of the pistol grip with no excess cartridge locking material hanging out. The handguns have a 8 shot rotary system on both sides of the magazine, so once fired, the shooter can change the magazine around and have another 8 shots. However with the MPX, it is essentially a belt fed pellet system, that is pushed up via the action of the charging handle, giving the shooter 30 pellets to shoot from a single magazine.

    I have owned and recently sold a licensed Beretta PX4 Storm pellet pistol replica that utilized the exact same magazine design. For the most part they are reliable mags that retain the pellets well, but by the time I sold it the mag had a nasty habit of becoming dislodged, sometimes before the gun ever fired. You’d be shooting gas and no projectile for a few rounds before you realized your rounds weren’t feeding. If Sig has fixed this issue, hopefully they will be a cheap and convenient training solution (even though the slide will not lock back on an empty chamber because no spring is used and the gun will have no way of knowing when it’s empty).

    Reviews that I have read said the velocity was much lower than advertised. Did Sig quote any velocities, does anyone know if this issue was fixed?

    How many shots will the CO2 last for both rfile and handgun? How is the trigger pull for both rifle and handgun? Also, why can’t someone make a PCP semi-auto air rifle llike this?

    • Julio

      SIG were saying in March 2015 that a PCP version was under development, but the CO2 versions have themselves been delayed, so I expect that pushes the PCP product into the far end of this year, or even into next year.

    Do they state that they are aluminium? I would be very surprised. Most CO2 air pistols & full metal airsoft replicas are made of much cheaper zinc alloy. These do look quite high quality though, so perhaps…

    • Ryan

      They are being advertised as “Metal Housing” from some of the other info I’ve read they are heavier than you would expect. They seem to start at $180ish

  • Stijn Van Damn

    does that break open like a normal AR?
    how does the lower look like on the inside?

    SIG Sauer is spreading too thin, IMO. They’ve branched out into optics and silencers. But airguns? Why? To ensure as many children as possible grow up to be dedicated SIG customers? There’s a reason H&K licenses it’s brand name for cheapshit .22LR clones; they’re an arms manufacturer that can’t be bothered making toys. Build a fan base by making sure your Gen1 products actually work as advertised.

    SIG Sauer has the potential to be the H&K that (many) American gun enthusiasts have always wanted: semi-auto versions of “what the pros use” with great reliability at a reasonable price, factory SBRs and a decent amount of focus on civilian customer service. They’re trying to do this but not doing it right.

    Anyone seen the slop between upper/lower MPX receivers? – I was ASTOUNDED!
    Anyone seen an MCX variant for civilian sale (not backordered) other than the 16″ 5.56mm?
    Did they fix the self-adjusting gas block issue on the MCX?
    Anyone seen the promised AR lower conversion kit for MCX uppers?

    SIG has many dedicated professionals and an enormous potential to be a phenomenal arms manufacturer. It’s a shame they’re going to squander some of that potential to make BB guns 🙁
