i recently bought a security six trigger, i got it today and cleaned it up. i have a problem i hope someone can help with, the spring in it is smaller than the one ruger sent me about a year ago. here are the trigger springs, the one on top is out of the trigger i bought, the bottom spring is what ruger sent me last year for my service six. did ruger send me the wrong spring or are there different spring sizes? as can be seen the spring ruger sent is larger. thanks
