The CO2 magazine is included in the offer shown here
Features:
- Slide, small parts and internals made of metal
- Grip & trigger made from robust polymer
- Surface of the grip ensures safe handling
- 21mm rail for attaching accessories
- Front sight is a glowsight which makes it easier and faster to acquire the target
- Can be operated with gas and CO2 magazines
- 14mm CCW for mounting tracers or silencers incl. threaded cap
- Two safeties (directly on the trigger and additionally integrated in the rail)
- PRO version
- Cut-outs in the slide to save weight
- Internals (hammer, valve knocker, sear, disconnector) made of steel
- Two-piece recoil spring
- Revised slide damping
- Begadi Stainless Efficiency valve
- Very good gas efficiency
- CNC piston head with ventilation
- Gun is supplied in a padded, lockable case
- Maintenance kit included in the scope of delivery
- We offer a mounting plate (Art.: 08420069) and rail (Art.: 08420068) for mounting reddots
Note: Please do not use these CO2 magazines at temperatures above 15°, as this can lead to problems with the outlet valve. This is then reflected in the fact that the magazines no longer fire properly and no gas escapes from them, only when you release some pressure do they work again! We would therefore rather recommend the use of gas magazines for the warm months. This is a KJW KP-13 specific problem and does not exist with the other KJW series.
Details on the PRO version:
In the PRO version, all components of the trigger group are made of steel, the sear is made of hardened steel.
Compared to the standard version, the nozzle has been reinforced and is now made of robust nylon fiber. This also withstands the high pressure of CO2 much better.
To ensure a perfect seal, the PRO version has a CNC-machined piston head with ventilation. This also ensures a smooth-running system in the cool-down area.
Due to the better seal, the energy can be slightly higher than with the standard version.
Our Begadi Efficiency valve made of stainless steel is already installed in this gun.
Thanks to its smooth operation and revised design, this valve ensures a significantly more constant energy output and reduces gas consumption by up to 15%.
For example, it is possible to fire up to 55 rounds at 0.85 joules from a small 1911 GBB magazine (data with ProTech gas at 18°C). This valve also has an additional O-ring on the inside, so that the firing piston is sealed to the rear when opened and no gas can escape.
The amount of gas that can escape per shot has been set so that the GBB can work without any problems but does not go into cool-down so quickly. As O-rings can always leak, we use a special material here that is resistant to cold. This does not contract in the cold and lasts much longer. All components of our valves are CNC-machined from stainless steel. Due to the high pressure of CO2, we work with a PTFE/Teflon seal which is also CNC machined
The Begadi Efficiency valves are not available individually, but only when installed in magazines or the GBBs as/where we offer them in the store. Customers who have purchased magazines or GBBs without Begadi Stainless Efficiency Valves from Begadi in the past can have the Begadi Stainless Efficiency Valves retrofitted by our workshop on request. This service is limited to magazines & GBBs purchased from Begadi

Maintenance Kit:
To ensure that you as a customer have many years of fun with the purchased weapon, we include some wear parts in the delivery, which can be replaced if necessary in the event of maintenance or damage, the contents of the kit are as follows:
- Piercing valve
- Original KJW exhaust valve incl. seals
- Magazine lips
- Magazine follower
Note on the additionally supplied original KJW exhaust valve:
KJW only supplies its GBBs and magazines including their original exhaust valves. Therefore, for the Begadi versions of the magazines, the original KJW valves are subsequently removed by the Begadi workshop and replaced by the Begadi Stainless Efficiency valves. The original KJW exhaust valve is then removed and supplied. We recommend keeping the original KJW valve as a backup. The outer O-rings can also be used for the Begadi Stainless Efficiency valve.
In the course of valve replacement by the Begadi workshop, the magazines are also tested, including firing tests in the corresponding GBB. These tests occasionally result in minimal traces of use on the magazines. Unfortunately, this cannot be completely avoided during tests.
