Disappointing

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 have...like 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!

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.

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...
