As known as JPWCC system (JohnWeak Chamber Checking) lol
The system can be found as a CustomButton in WristMenu.
Click it to toggle the system.
Once the system is on.
Grab a pistol, slightly throw it upward then catch it (Just like how JohnWick does).
On the second grab you will hold the pistol by the slide and the slide will move rearward to show the chamber.
and third grab will return to normal pose.
This only works with pistols that aren't harnessed to QuickBeltSlots.
PlayerBody hands pose may not look good when checking chamber.
The system has a time cool down, if you failed to catch the gun in time, or you grabbed another different gun, it will return the gun to normal pose.
1.0.0 Added the function in wrist menu.
1.0.1 Tweaked handpos when checking chamber so now it should look better with playerbodies.
