I sold my Diana 430l to my brother in law. He likes the gun but the sear spring, in the TO6 trigger, has broken twice. He was able to order 2 spare springs and a complete trigger unit from PA. He had one of the spares break, installed complete TO6 trigger and after shooting a while, spring broke. PA said not selling any more springs or triggers. Anyone run into this with the TO6 trigger. If the last spring breaks, he is sol unless a fix or new trigger can be found. Any help would be greatly appreciated. Don
