Another quick trip to the range a couple days ago. I shot with both the original guide rod and springs and the Lakeline SS rod and springs. Noticable difference in recoil. Softer felt recoil with Lakeline, not quite as snappy. Nothing wrong with the original, but more comfortable . Great to have a good known backup assembly on hand in the original springs and rod. Not a lot of money for a noticeable amount of difference.
