I was really looking forward to testing the ASG 1911 US-C CO2 Blowback BB Pistol in the Replica Airguns Sea Can Indoor Shooting Range, mainly because it offers a new type of system for loading BB’s into the Breach that does not require any trigger effort while still providing more efficient CO2 usage. I am happy to say that the ASG 1911 US-C CO2 Blowback BB Pistol does provide a higher velocity with this system, more efficient CO2 usage and it still maintains good accuracy with a really great feeling single action only trigger, the same as you would fid on a classic 1911! If you are mainly interested in details and specifications along with more close up video of the ASG 1911 US-C CO2 Blowback BB Pistol then watch my Table Top Video Review.
So let’s get right into the performance… As always I started out with my Chronograph Velocity Test to see what the actual fps is for the ASG 1911 US-C CO2 Blowback BB Pistol. ASG claims 420fps which is about 100 fps higher than what you can expect best case scenario from a KWC Full Blowback CO2 1911. My 5 shot average in this test was 372fps using a brand new CO2 in medium temperature settings. In a warmer shooting situation you may get a little bit higher fps but I would not expect a lot more out of this pistol. Still I would say on average about 70fps faster than the Full Blowback KWC 1911’s I have tested in the past.
Moving on to my accuracy test, I shot 10 rounds at a fresh paper target from 30 feet away using a semi rested shooting position with my hands rested on a sand bag up front and sitting on a stool in the back. My 10 shot grouping ended up being around 2 inches which is a little on the tighter side than you would expect from most Blowback BB Pistols. It did shoot a little bit low but side to side was very well centered. The trigger felt really good while the blowback action is very fast and snappy as compared to the full blowback KWC 1911’s I have reviewed in the past.
I was very happy with the performance of the ASG 1911 US-C CO2 Blowback BB Pistol overall! The trigger was short and light as I was hoping for, the velocity was perfect for a blowback CO2 Pistol getting really close to 400 fps, and the partial blowback action although not as aggressive as some otters blowback CO2 BB Pistols was still strong enough to give some good feedback while shooting. One point I would like to make with this pistol is to not take the magazine out or rack the slide between magazine reloading as you can very easily double load a BB into the breach either resulting in a double shot or possible BB jam. If you want a Blowback 1911 with that classic 1911 trigger and a little bit better performance than most other blowback 1911’s ,then the ASG 1911 US-C CO2 Blowback BB Pistol is a really great choice!
Type: Blowback CO2 BB Pistol. Manufacturer: Distributed by ASG. Model: 1911 US-C. Materials: MostlyMetal. Weight: 1.9 pounds (874 grams). Total Length: 8.7 inches (220mm). Barrel: 4.7 inches (119mm) metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto blowback, SOA trigger. Ammunition Type: .4.5mm steel BB’s. Ammunition Capacity: 18 round drop out full size metal magazine. FPS: Claimed 420.
Trigger Pull: The trigger pull on the ASG 1911 US-C CO2 Blowback BB Pistol is surprisingly really good as this is a new design mechanically different than the standard KWC 1911. There is a slide nozzle on the top of the magazine that pushes a BB into the breach area of the barrel and seals off the magazine for the barrel allowing for higher fps and I would imagine better CO2 efficiency. There are other Blowback Airguns that do this but most incorporate the trigger force to push the slide nozzle forward causing some friction and creating more of a double action trigger feel. I believe the ASG 1911 US-C CO2 Blowback BB Pistol uses the blowback action to engage this slide nozzle allowing for a true short and light single action trigger. Which the ASG 1911 US-C CO2 Blowback BB Pistol does have.
Accuracy: At this point I have not shot the ASG 1911 US-C CO2 Blowback BB Pistol or done my Field Test Performance Video. I really have no idea what to expect from it as this a new design I have never seen or shot before. I have high expectations based mainly on the advertised specifications but also from my observations looking over the mechanics and how this Airgun feels in the hand. Hopefully it performs as good as I am wishing for…
Build Quality: The ASG 1911 US-C CO2 Blowback BB Pistol has good fit and finish, I would compare it to a KWC 1911 in this department, I have a feeling it may be made in the KWC factory as the manual uses some of the same graphics found in most KWC manuals. I could be wrong here. That said the ASG 1911 US-C CO2 Blowback BB Pistol is mostly all metal with the exception of the pistol grips as expected.
Realism: The ASG 1911 US-C CO2 Blowback BB Pistol looks exactly like a real steel 1911 with the exception of an additional pin in the frame. The slide also does not cycle as much as a real steel 1911 or even like a standard KWC 1911 and field striping will not be done in the conventional manner since the slide catch release does not easily come out. All that said I feel like tis 1911 airgun design may be a nice compromise between performance and realism.
Pros:
Has that well liked KWC 1911 look but with different internals.
Looks to have a nice short and light single action only trigger.
Because of new type design I expect really good fps and lots of shots per CO2.
All working parts just like a real steel 1911.
Working safety and grip safety.
Full size drop out metal magazine that holds the CO2 and 18 rounds.
Integrated CO2 Allen key tool.
Recessed barrel for realism.
Blowback action for simulated recoil and a smoother trigger.
Good overall fit and finish.
Cons:
Painted markings on slide are a bit much.
Field strip is not conventional.
Sights are not adjustable.
Comments:
I am really optimistic that the ASG 1911 US-C CO2 Blowback BB Pistol will be a real winner here as it has a lot going for it! First of all it’s a 1911 and who doesn’t like a 1911? It is also a really solid replica on its own rights so it should check most boxes here with its blowback action, full size drop out metal magazine, nice SAO trigger and all metal build. On top of this all ,the specifications look really good with higher velocity than the standard KWC 1911 and I am also assuming better CO2 efficiency. Take all of this into account and the ASG 1911 US-C CO2 Blowback BB Pistol could be the new 1911 standard to go by.
In this Update Preview Video I take a look at three CO2 Air Pistols from ASG, Gamo and Barra. All shoot 4.5mm steel BB’s and one can also shoot .177 caliber pellets. two of them have blowback action. Two are also styled after the popular 1911 Semi Auto Pistol. The ASG 1911 has a unique magazine and chambering system that is the first I have seen of this in a Blowback Airgun. It offers with blowback operation along higher fps and a nice light semi auto trigger, which is a combination not offered in many Airguns.
