dwhite! did my first CGW mod,s 8 yrs ago on my P-01 and the decocker cage was a bear! Do the kit in segments! trigger group, hammer, springs. polishing etc. when you had enough ,take a break and when your mind is up to it again be it hours or days later get back after it. label all your old parts as original and put them in the little bags that has the corresponding CGW parts . I just got a pro pkg for an sp-01 manual safety and i will be doing the mods after the 22nd when i pick the gun up! i have a 110 dremel with felt wheels, and i also chuck q tips in the dremel and use metal polish with them. I have 1000,2000,3,000 wet or dry sandpaper and also have 3,000 and 5,000 grit polishing cloth foam backed that i will be using . looking foreward to a project that keeps me busy !lot's of good inf0 here in the gunsmithing and CGW sections as well as utube videos. good luck with your project!
