In this Indoor Field Test Shooting Review, I put the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol through its paces and find out what we can expect in terms of power and accuracy by first averaging 5 shots through my Chronograph to see what the real world velocity is in fps. I then shoot 10 rounds into a paper target setup 30 feet down range to see if I can get a decent grouping somewhere near the bullseye out of the box. If you are looking for specification and details along with some closer up video of the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol then make sure watch my Table Top Review located here.
First up I performed the power test using .20 gram Airsoft BB’s. I put a brand new 12 gram CO2 in the pistol and averaged the first 5 shots which gave me a 318 fps average. The actual shoots were as follows: 331, 322, 315, 312, 308. I didn’t take notice of the temperature but in generally I keep my Sea Can at around room temperature so not overly warm or cold. There is a barrel extension that comes with this Airsoft Pistol which will give you a bit higher velocity when installed, but I did not test the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol with the barrel extension on it as mine was broken.
Moving on to the accuracy portion of the testing I setup a fresh paper target 30 feet away and put 10 rounds into it while sitting on a stool in the back with my hands resting on a sand bag up front. This gives me pretty good stability but is not perfect and there is always going to be some human factor that can effect accuracy a little bit. That said I did manage to get around a 2.5 inch 10 shot grouping with the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol that was pretty well centered hitting the target just a tad low and to the left but pretty close to center target.
All in all the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol did a good job once I took the broken off threads out of the barrel. The trigger is really nice on it, maybe even a bit light but you will get use to it over time. The blowback is snappy and the gun holds well in the hand, a real pleasure to shoot! I did notice the slide spring feels a bit weak when you release it as it does not snap into place with a lot of authority, but this does not effect the blowback action at all and the gun shot without any problems or hiccups. If you are looking for a quality Glock styled Airsoft Pistol then the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol would make a great option for sure.
Type: Blowback CO2 Airsoft Pistol. Manufacturer: Distributed by KJ Works. Model:KP-13 TBC. Materials: Metal & Polymer. Weight: 1.7 pounds (770 grams). Total Length: 8.25 inches (210mm) Barrel: 3.7 inches (95mm) metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto blowback, SAO trigger. Ammunition Type: .6mm plastic Airsoft BB’s. Ammunition Capacity: 22 round drop out full size metal magazine. FPS: Claimed 360+.
Trigger Pull: The trigger pull on the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol is what you would expect from a true Single Action Only Trigger, which is nice and light and relatively short. There is some initial take up but you can feel the point near the back where the release kicks in which is extremely light and predictable with no play in it. Of course you will have to rack the slide in order to place a round in the breach and fire the first shot, after that the blowback action will do all the slide cycling for you.
Accuracy: At this point I have not shot the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol or made my Field Test Performance Video. I have already made a full Field Test and Shooting Video of the non-TBC version which is virtually the same Airsoft Pistol but without the threaded outer barrel extension. You can watch that Filed Test Video here where I get around 350 average fps and close to a 2 inch grouping shooting at a paper target setup 30 feet down range. Stay posted for my Full Field Test Shooting Video for the TBC version down the road.
Build Quality: The KJWorks line of Airsoft Guns is know for overall good quality so I expect the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol to be just the same. From my testing with the non TBC version and my initial first impressions, everything looks really good, fit and finish are excellent and as expected you will find metal parts and polymer parts in all the same places you would find them in a real steel modern semi auto pistol.
Realism: The KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol is not an exact replica of a specific semi auto pistol but you could say it looks a little bit like a Glock ;) You need to be careful when it comes to Glock as they do not like it when companies copy their guns and rightly so. There is enough differences with the KJ Works KP-13 TBC CO2 Blowback Airsoft Pistol so it should not set off any red flags over at Glock. It’s good that there are various color options, tan, grey and black. It does seem that only the Tan and Grey two tone versions are available in the TBC version while the black version we seem to have available in the all black non-TBC version.
Pros:
Metal and Polymer with decent weight and good feel to it.
Heavy Full blowback operation.
Excellent fit and finish as always with KJWorks pistols.
High capacity full size drop out magazine that holds the CO2 and 22 rounds.
Well hidden safety incorporated into the serial number under the barrel.
Working trigger safety.
Super easy to see in all conditions fiber optic sight up front.
All working components like the real steel Glock styled pistol.
Comes with extended threaded outer barrel for adding a possible compensator or mock-suppressor.
Comes with barrel extension for higher velocity shooting.
Would make a good training weapon if you are use to using Glocks
Comes in Tan and Grey two tone options also.
Can use CO2 or gas magazines.
Field strip-able.
Cons:
Sights are not adjustable.
Would have liked the addition of white dots or outline on the rear sight.
Slide spring could be slightly heavier.
Comments:
Let’s be clear, the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol is not a Glock Replica. It is different in many ways, the idea here is that it is close enough to be a good alternative if you are use to shooting Glocks and want something to train with that looks, feels and functions a lot like a traditional Glock. I am hoping the TBC version performs as well as the non-TBC version shot for me when I made my original Field Test Shooting Video back in 2023. For me the KJWorks KP-13 TBC CO2 Blowback Airsoft Pistol checks all the boxes… Full blowback operation, a very good trigger, lots of realism and I am sure good performance based on my past review.
