Heavier firing pin spring (6.5 lbs vs. original 5.5 lbs) is designed to increase the reliability of firing hard primers (such as S&B). It is ideal to combine it with our stainless steel channel liner sleeve. When used in combination with the Glock Performance Trigger, there is no increase in resistance (this is due to the fact that it is a fully single action trigger) - with original trigger, the resistance will increase by ±350g.
