Thunder Mountain Custom hammer / main springs are manufactured from the best Chrome Silicon wire availble.  Then our springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability. The hammer / main spring is one of the most over looked springs in the 1911.  The hammer / main spring allows adjustment of trigger/let off to individual needs.
