R2 trigger spring question

My R2 trigger is still giving me problems. Basically,whatever game i'm playing, and whatever action is assigned to that button, acts on its own.

I've broke down the controller , following these guides, and everything seems to be in working order. Only thing i can think of is the spring itself is somewhat warped, stretched out of shape , or something along those lines.

Was wondering if there is a picture shot of how the spring should look and if the center (circle in middle of spring) part of the spring is supposed to be snug on the pin is located or if a little play is normal. ?

Can attach pictures if necessary. Thank you in advance for any time taken on this. This website is the best and very informative. Appreciate everyones time and effort. Keep on gaming..
