Variable Power Recoil Spring - .45 ACP & .38/9MM
Variable rate springs function correctly with a wider range of loads than fixed rate springs can. Rate increases as spring is compressed; gives greater protection against frame battering, more consistent lockup and improved feeding, while allowing easier manual cycling of the action.
