KSC Cougar Spring
 

Note: Terminology may not be entirely right.

I have a KSC Cougar GBB and after finally getting it to cycle properly I've found that the return spring (spring that returns the slide) seems to be incredibly weak. It'll do the job if it has momentum but when I reload and release the slide the action seems really weak and 60% of the time the slide jams. I can fire it without jamming but I can't make it through an entire mag. I'm hoping that a new, stronger spring will solve this problem.

What would I be looking for in the way of a spring that returns the slide? Are the springs generally generic or am I going to have a hell of a time because it's a cougar?

Can no one help?

correct me if im wrong but isnt a cougur a m9 varient if it is you sould beable to use a m9 spring i belive king arms one will work i use them on my kjw and it works dreams i think they can be used on ksc also.
