I´m glad you´re enjoying this as much as I did by working on this project.
Yes, as NYCMedic has already explain i had changed all internal components, but i kept the original GI mainspring which i reduce in order to fit the new dimentions of the frame and allow a higher fit to the mainspring housing and seat the sear spring to free and funtion correctly, i had to reduce all three legs to work properly too. Same with the hammer strut to allow a correct relation with the hammer. Then i cut the slide and barrel with the same dimentions, I permanently added the cone sleve then cut the new crown and re fit the barrel direct to the slide, about the recoil spring system, well i never could get my hands on a aftermarket system but i tested a couple combination and i end up with an Officer´s double spring and cominolli buffer system, then i start all the custom touches, flaring and cut the ejection port, cut a high grip, fit and set a long ejector, fitting the low mount sights, dehorn all the gun etc..
Trigger is set at 4lb clean and crisp but solid even after this i know i would have to have some consideration with this gun, after all it was a single prototype. we are talking 96/ 97 when i start playing around with this project then i test fire it first time on 98, yes right on that time you couldn´t find those factory sub comps 45 so popular and ease to get on this days but the Adventurer´s from C&S in which i felt in love afther the 95 CH issue and of course the Detonics which never really fascinate me just because they didn´t kept the original 1911 lines IMHO.
Till today reliability is at 100%, precision has been mantained 4" to 4 1/2"at 25 that´s quite enough for this little GI coned barrel.
Btw. The only work i haven´t done myself was the lower frame welding ( Twice after i crushed it under my 39"x18" Suburban tires on the first trip to the range, it wasn´t my intention but... it happened

) the new barrel crown whas cutted in a lathe and the aproximated mill cuts by .02 of ml.
All other cuts and fittings has been developed by small hand tools only.
Now I would like to change the trigger for a solid one in order to get a more classic look plus.. cut a french borders, also finish the blending of the mag well to the frame and a pair of custom VZ grips.
Well after all this i would apply a dark gray color teflon moly coat, well.. if I ever get a bottle of it.
