  • STI Duty One pistol
  • Uses 12-gram CO2 cartridges
  • 20-rd mag
  • Slide moves in a realistic blowback action!
  • Very realistic 1911 lookalike
  • Fixed sights
  • Manual safety
  • Weaver accessory rail
  • Includes gun, 5 Swiss Arms CO2 cartridges, ASG fake silencer and 1,500 Umarex steel BBs


About as realistic as you can get when it comes to 1911 air guns. The slide moves just as it would in a firearm. The air pistol is even better than the firearm -- because you get 20 shots from a mag!

We put together this kit so you have everything you need the minute your package arrives. You can start shooting right away.

If you like the 1911 frame and can't get to the range to practice with your firearm, this gun will go a long way toward helping you maintain proficiency. You'll also save a lot of money by shooting steel BBs instead of live ammo.

Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area, as rebounding ammo can hit them, too. Never shoot steel BBs at hard objects (including metal targets) or water, as that increases the chance of ricochet.

Things I liked: Hi I just got home a couple hours ago to find my new STI Duty One by ASG. My second ASG product in a week! Ha.. My first is was the CZ 75 PO7 Duty..I fell in love.. I had to get another to add to my collection and I ordered the kit and the larger frame pistol in the 45 acp format. I've already used up one CO2 in the basement range and I'm very very happy. Great weight snappy blowback solid and 80 full power shots with one CO2.. Very accurate with the laser ..

Things I would have changed: I think it's just a little light in the grip even loaded. The door that opens up to instal the CO2 should be metal not that the plastic one is cheap but to add grip weight.. Just a little.And I would like to see white or some highlighting on the sights. I may paint my muzzle sight white.

What others should know: I only just got this gun literally.. I'm writing this down literally just after firing its first CO2 and I'm so far impressed. I have big hands and the full size frames really help. I will do another review after I fire this awesome great looking 45.or after I've owned it longer I hope I don't jinx myself it did seam a little dry so I did lightly P ellgun oil the trigger. I've had dry Hatsan rifles before so maybe I'm being paranoid but a little Pellgun oil can't ever hurt.. I will b very thorough with my next review after using it more but those 80 rounds were smooth and impressive definitely in the high 300's or close to 400 fps..

Things I liked: Looks. Weight, nice report when fired and like slide recoil. Rear sight is adjustable for wind age.

Things I would have changed: Threaded fake silencer should be a barrel extension and not a hollow tube. This would aid accuracy.

What others should know: The front sight is so tall, it shoots very low even at 20 feet. With 220 black sandpaper Around a flat file, I reduced the height by one half. Then put a dot of white paint on it to improve the sight picture. The slide will lock to the rear when empty only now and then. Haven't figured that one out yet. It maybe a weak spring that moves the slide lock upward. Then as others have noted the empty co2 powerlet does not come out of the grip easily. I use a small magnet to help it out. Some other suggestions are tie a string or ribbon to it.

Things I liked: Unfortunately the fake slencer does not work with the model shown as the model shown DOES NOT HAVE A THREADED BARREL. The box that was sent showed the upgraded model WHICH IS THREADED but the lower end model...shown in this picture - was in the box. YES...they did refund the ENTIRE purchase price and shipping and also paid for all return shipping. Still....very disappointed.

Things I would have changed: Pyramyd Air should remove this ad and replace it with the model that has the threaded barrel to accept the fake silencer.

What others should know: See Above

  • Tom M from USA asked:

    I found a video on you tube that shows the rear sight is adjustable on the STI Duty One 1911 co2 bb pistol. It that true? And is the fake silencer actually a barrel extension and does it add to accuracy?

    • Rod from USA asked:

      I have a Duty1 and I have found that bb's are accumulating behind the trigger. I need instructions to field strip it so I can remove the bb's and clean it, and I have looked all over youtube and googled thei dickens out of it with no luck. I have been told that it field strips like a standard 45 cal 1911, but that doesn't appear to be so. The slide release will not come out. I know there has to be instructions somewhere, but where? Please help, where can I find them?

      • Dan the Man from USA:

        You would want to contact ASG at 805-522-7707 for assistance.

      • Jerry from USA:

        Sir, I would recommend calling ASG at 805-529-7707
