about a year ago i got a great deal on a blued ruger service six, i still have it and carry it daily as my ccw. i bought when funds allowed extra parts, i now have every extra part for the gun except the trigger and hammer. do these ever fail under normal use? reason i'm asking a friend of mine is parting out his gun and he will let me have them both for $30 which includes the trigger guard with pawl and transfer bar. will the trigger guard just fit on mine without gunsmithing? his blued guard is almost 100% good bluing and mine is about 50%. thanks for any help
