The Ghost 6.5 lb Super Duty Extra Power Striker Firing Pin Spring for GEN 1-5 Glock models 17, 19, 20, 20SF, 21, 21SF, 22, 23, 24, 25, 26, 27, 28, 29, 29SF, 30, 30SF, 30S, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43

The Ghost manufactured 6.5 lb Super Duty Extra Power Striker Firing Pin Springs are a must for all 45 ACP, 45 GAP & 10mm Glocks. These bigger guns use 9% heavier firing pins but come with the lighter weaker 9mm firing pin springs which will eventually cause light primer strikes. While a great upgrade for the larger caliber Glocks they are also highly recommended for all other Glock models to insure positive primer strikes insuring that your pistol fires under the most extreme conditions. Ghost Inc springs are better than Stock Glock springs. You will feel about half a pound heavier difference in your trigger pull weight when switching out just the striker spring. All Ghost Inc products feature a Lifetime Warranty direct from Ghost Inc which covers product(s) against manufacturer defects, user installation and use of the product(s).
