All jokes aside 
Recently upgraded my M&P pro with the APEX trigger kit. Also upgraded to a KKM precision 9mm conversion barrel with all the mags and hoopla! Wondering if there is any advice on swapping out the recoil spring and where I could possibly locate a better one to help manage recoil when firing .40. Any and all advice would be appreciated!
