ISMI 12.5 Lb Recoil Spring for 5" 1911 Models & 4.7" P320 Models

ISMI Premium Springs are manufactured exclusively with certified aerospace specification alloys such as chrome silicon. Their springs are heat treated, shot-peened, and stress relieved after winding to enhance performance and durability. Chrome silicon springs have 10x the life of traditional music wire springs, and they hold much better tolerances during compression and cycling. This spring not only features improved materials over the stock components but will also lighten up the trigger feel from the stock 16 lb weight down to 12.5 lb's.
