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.
