ok so yesterday i was dissassembling my 21a to see if i could lighten the pressure required to take off and apply the safety, anyway i lost the safety plungers spring. its out of stock at numrich and brownells doent seem to carry anything like it, so does anyone know where i can find one? can i order directly from beretta? i know thay still make 21a's so i would assume they still make parts for them. please help!
