KJW KP-05 Safety Problem

[Don-Faheezy]

Hi guys, I have a KP-05 and when I pull the trigger when the gun is loaded and the safety is on, it will automatically fire when i pull the safety down. its really weird. does anybody have any idea whats wrong?

also the beaver tail safety does not always work.

i can fire the gun without the beaver safety being pressed.

ALSO

if i pull the trigger hard when the safety is up and the beaver tail is NOT pressed it can also fire.

the leaf spring is placed correctly...

any help is appreciated
