Description

Fully licensed by small arms manufacturer STI International, the non-blowback DUTY ONE CO2 pistol is a 1911 replica ready for action. Thanks to the easy to operate loading system, steel BBs are stored in the drop-out magazine, while the CO2 cartridge is cleverly located in the pistol grip.

The frame of the semi-auto pistol includes a front Weaver rail for mounting light or laser, and the high rise beavertail grip offers a firm, comfortable hold on the gun. You'll recognize the STI logo on the grip, and appreciate the unique serial number.

When you can't get to the range to practice with your firearm, this CO2 powered pistol will help you keep your shooting skills sharp. And you'll save yourself some money by shooting BBs versus live ammo.

I like the steel mags. It has good weight. I can shoot quarter size groups at 10 yds consistently.

The trigger pull could be better. white dot sights would be good.

The gun is a great gun. Looks and feels like a real 1900

I would like to have had a gas cylinder with the gun. They sent everything else with it to start shooting except the gas.

This is a excellent pistol, it looks real, heavy duty and very well made. This is my first air gun and I feel that I got a great air gun.

I wasn't sure about how to fire and I still may be doing it wrong, so better instruction would be helpful. I finally figured it out i think and that was that the throw back has to be pull back for each shot. I was trying to fire it 10 times by pulling one time. so if I'm doing this wrong please let me know.

I was able to fire approx 30 shots with one co2 tube.

BBs and CO2 are easy to load.

The trigger is awful. It actually seems easier to squeeze in double action but only because the release point moves out. In single action, the trigger is very hard to squeeze and is nearly inside the trigger guard before it releases. Two fingers on the tip of the trigger helps but it is still dreadful. Adversely affects accuracy. Also, spent CO2 cartridges are difficult to remove, requiring a screw driver to pry it part way out and pliers to grasp it and pull it the rest of the way.

I bought this pistol because the ASG CZ compact has an awesome, almost match grade trigger but, unfortunately, has an awkward and difficult to operate loading system for the BBs.. I was hoping for the same trigger and better loading. I got the better loading, but the trigger pretty much ruins the gun. An unforgivable shortcoming.

I like that this pistol shoots in single and double action! The blowback version is single action only. The finish and engraved branding looks excellent. The co2 access is well designed. Velocity is OK. Not great. It is a really great quality pistol and that looks and feels great to shoot. I really like the thumb safety and grips.

I would increase the power to 450-495 fps, because any air pistol that looks as cool as this should be able to blast BB'sstraight thru large soup cans. 390 fps will punch a hole in but not out . I would like to have seen a grip safety, at least like the one on the Crosman gi1911bb . I like white dots on my front sights.

Love your airguns :)

WELL SAID PAPA!!

Gregory Apr 01, 2018

These reviews are opinions, and in answering the question that PA asks: "things I would have changed", i offer only my opinion, which in this case was more velocity, a functional grip safety and white dot on the front sight.

Airgun Papa Nov 22, 2017

Gregory, In following your reviews you seem to suggest often that a pistol should have more velocity. Well, there are guns that will give you that power level. Other reviewers state something like, "It needs to be quieter, I would trade off some power for a quieter pistol". That exists also if you look around. We each have preferences and that is partly why there are so many offerings with different power levels, prices and features. We do not need to turn every product into something else to find what we want.
