When I cut mine it got cerakoted which is now showing a bit of holster wear at the nose......when its gets tatty I will just have the stainless shot blasted and run a raw stainless finish.
That pistol looks great.....congrats! The only other "issue" when the gun has an optic mounted is the extractor pin...it needs to be shortened since it now contacts the bottom of the optic base or plate if you have one. This means the optic needs removed to remove the optic...PITA. I actually drilled a relief hole in my optic mounting plate to allow the pin to pass thru into the plate, this means while I still need to remove the optic to remove the pin, now I dont need to also remove the plate. I probably wont remove/change the extractor but once a year so its probably ok.
Now that I have cut the slide the balance is very good and it transitions well for a full size gun.....very controllable and very accurate.
I really dont have an issue with the stock safety OTHER than the two hands needed to push it and release the mag.....WAAAY to strong a spring......I stretched the stock release spring and cut about 2 coils off....now its perfect
