Type: BB air pistol
Manufacturer: ASG
Model: CZ 75 P-07 DUTY
Materials: Metal slide and polymer frame
Weight: 1.8 pounds
Barrel: Metal non-rifled
Propulsion: CO2 x 1
Action: Semi auto blowback, single action
Ammunition Type: 4.5mm BB's
Ammunition Capacity: 20 round magazine
FPS: 361

Trigger Pull: The trigger pull on the ASG CZ 75 P-07 DUTY is nice and light due to its true blowback operation that cocks the hammer back with each shot taken. For some reason there is a slight stickiness in the trigger when the metal magazine is loaded, but it does not affect the light weight of the trigger pull.

Accuracy: I shot the ASG CZ 75 P-07 DUTY gun at a target from 20 feet away in a free standing position, and it performed well getting a 1.5 to 2 inch grouping right in the center of the target. The sights are non-adjustable, but for me there was no need to adjust them. My Chrony testing with a five shot averaged result was 353 fps.

Build Quality: ASG did an awesome job designing and making the CZ 75 P-07 DUTY, they didn't seem to compromise on anything! Everything that should be metal and polymer is the same on this as the original, and the fit and finish is excellent!

Realism: The ASG CZ 75 P-07 DUTY is as close as you can get to the real steel, the only real giveaway is the slightly longer but-plate on the magazine (probably to allow for the CO2 screw tab). Everything about this gun is saying it's the real deal right down to the licensed CZ trademarks and the 9x19 caliber markings on the slide and ejection port.


  • Great usage of metal and polymer!
  • Realistic true blowback action.
  • Great looking gun with nice two-tone finish, and lots of attention to detail.
  • Good power, accuracy, and CO2 efficiency for a blowback gun.
  • Very usable sights.
  • Metal magazine.


  • Very hard to get this gun in North America.
  • Magazine but-plate is a bit on the long side, only telltale sign it's not the real 9mm version.
  • Trigger is a bit creepy when you have a loaded magazine.

Comments: I highly recommend the ASG CZ 75 P-07 DUTY blowback BB pistol to anyone looking for a very high quality BB pistol that does not compromise performance, build quality and realism. It may be a bit higher priced then some other blowback BB shooters on the market but it definitely sets a new standard for the others to try and achieve.

An ASG BB pistol meant to be on the cheaper side with the NBB, that trigger, and just overall presence of workable features. You can rack the slide to cock it there is not blowback. The double action trigger I found a little uneven and even though single action is nice and light it is also not completely predictable. I find myself spraying shots all over the place when I accidentally fire. Even when I do get a nice smooth rhythm the more than powerful enough really uninspired 1911 replica still has trouble with any kind of tight grouping. I think this is quite poor value for the dollar and really I only bought it to put the silencer I have on it. Now that I think about it I might not have bought it from here because I think I bought it with the silencer. Nonetheless, not the best offering by AGS.

Truth be told

I really like the gun, haven't used it much due to weather and as far as accuracy it could be me just not used to the gun as yet.

a must ALL 1911 replicas

I was not disappointed when I received my duty one after watching the review...this gun feels awesome in hand...handles well and has a nice blowback feel and isn't too shabby in anti the accuracy depth either...A must have for your collection in my opinion and isn't overpriced! Great value!

ASG STI Duty One 1911 Non Blowback CO2 BB Gun Field Test Shooting Review

ASG STI Duty One 1911 Non Blowback CO2 BB Gun Field Test Shooting Review

148 - 11/22/2021 8:07:07 PM

Here is my follow up Shooting Field Test to my ASG STI Duty One Non-blowback Table Top Review. During this Field Test Shooting video review I not only shoot my Non-blowback STI Duty One version but I also compare it to the Blowback ASG STI Duty One to see if fps and accuracy are effected when adding Blowback to the equation? I shoot 5 rounds through my Chronograph with both guns to get an average fps and I also step back 30 feet and setup resting my hands on a sand bag and standing in the back for a fairly secure shooting stance. I did my standard 10 shot grouping for my accuracy test from 30 feet away. Read full article here: Buy the STI Duty One NBB In Canada: Buy the STI Duty One NBB In the US:

ASG STI Duty One 1911 Non Blowback CO2 BB Gun Table Top Review

ASG STI Duty One 1911 Non Blowback CO2 BB Gun Table Top Review

143 - 11/22/2021 9:18:21 PM

Type: BB air pistol. Manufacturer: ASG. Model: ASG STI Duty One 1911 Non Blowback. Materials: Metal slide and polymer frame. Weight: 1.8 pounds. Barrel: Metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto blowback, single action. Ammunition Type: 4.5mm BB's. Ammunition Capacity: 20 round magazine. FPS: 407. In terms of comparing the Non Blowback version of the ASG STI Duty One 1911 to the Blowback version without actually shooting it, they are pretty much identical except for the double and single action trigger found on the Non Blowback version. Even the slide seems to work the same. The big difference will be when I shoot the Non Blowback ASG STI Duty One. Will it shoot with a lot more FPS and will the reduced slide movement give it more accuracy? I am assuming yes to both of these question but I guess we will all have to wait and see when I do my official Shooting Field Test Comparison...
