KJWorks KP-05 1911 HI-CAPA Blowback Airsoft Pistol Table Top Review

No Comments

Type: 6mm Plastic BB Airsoft Pistols.

Manufacturer: KJWORKS.

Model: KP-05 (1911 Replica)

Materials: Metal slide & frame.

Weight: 2.29 pounds (1040 grams).

Barrel: Metalnon-rifled smooth bore.

Propulsion: 12 gram CO2.

Action: Blowback, Single action only.

Ammunition Type: 6mm plastic Airsoft BB's.

Ammunition Capacity: 30 rounds.

FPS: 366+ fps.

Trigger Pull: The trigger pull on the KJWORKS KP-05 is what you would expect from a true 1911 single action only trigger, it has very little take up with a smooth crisp and light release to it.

Accuracy: I shot the KJWORKS KP-05 from 20 feet out in semi rested position and got very good test results. I was able to place 10 rounds in under 1.5 inches and getting four shots right in the bullseye making the shot placement very good even without adjusting the sights (which can be adjusted for windage). The KJWORKS HP-05 1911 styled HI-CAPA Airsoft Replica shot right around 300 fps range while conducting my 5 shot average chrony testing which was surprisingly low for the CO2 magazine version, this may have been a temperature or CO2 related condition, when I conduct my full Field Test Shooting Review, I will review this and see if we can do better? I also got two full 30 round magazines worth of shots which is what you would expect from this style of full heavy blowback airsoft pistol.

Build Quality: I am extremely impressed with the build quality of all the KJWORKS Airsoft guns so far, the fit and finish is the best around on any of my guns including my 4.5mm steel BB shooters. After shooting several magazines worth of BB's, areas that are painted like the metal friction areas show very light wear which is rarely the case with metal built blowback airguns. Again the tolerances between the moving parts like the slide and frame are very tight showing excellent workmanship and machining from KJWORKS.

Realism: The KJWORKS KP-05 6mm Airsoft pistol is a replica of a High Capacity styled tactical 1911 45 Auto and is a great looking and functioning replica. You will not find any actual licensing on this pistol and the CO2 magazine does stick out a bit to accommodate the 12 gram CO2 but other than that this Airsoft pistol looks and works near exactly like a real 1911 tactical semi auto and is fully field strip-able. I really like the updated more tactical add ons like the tactical rail, machined trigger and hammer, white dot adjustable sights, wrap around grips and ambidextrous safety.

  • All metal pistol with good overall realistic weight to it.

  • Full heavy blowback operation.

  • Typical KJWORKS excellent fit and finish.

  • High capacity magazine 30 rounds.

  • Very good accuracy and well centered on target.

  • Nice replica of a High Capacity Tactical 1911 styled pistol.

  • I like the stainless highlights and ambidextrous safety and Rail for accessories.

  • Fully field strip-able.


  • Shot a bit low Feet Per Second for me - should do better?

  • CO2 magazine is long to accommodate the 12 gram CO2.

  • Slide is heavy enough but seems to be a bit sluggish which is kind of a 1911 trademark so that can be taken as good or bad.


The KJWORKS KP-05 1911HI-CAPA is another excellent full blowback Airsoft pistol from KJWORKS. The HP-05 is a classic upgraded more modernized version of the 1911 semi auto pistol which is a great foundation to build any pistol from. I found the CO2 usage to be decent on the KP-05 but felt that I should have been able to get more fps out of this pistol, I will be testing the KJWORKS KP-05 again and hope to see some better results in this area. With that aside, the KP-05 1911 HI-CAPA is a great shooter and as is, with its high capacity magazine would be a perfect sidearm for any Airsoft related squirmish or even just for honing up your shooting skills when getting to the gun range is not an option.
