I carry a HK P2000 with the LEM trigger. My understanding is that after you chamber a round, the hammer spring is basically cocked. So...my hammer spring stays cocked continually. This results in the lighter trigger pull if I understand the LEM trigger correctly. What are recommendations in reference to replacing this spring due to spring compression over time? Is it necessary? I believe mag springs should be replaced and feel like the same principle applies. Thanks for your input.
