Great in-depth video. The P-09/07 is way easier to do these upgrades on. I did it in about 1 hours I spent more time on the decocker spring (about 20 mins getting it reinstalled), and about 10-15 getting the lighter reset spring in. The rest is cake walk I could have done the whole thing in about 30 mins if not for the decocker spring being a PITA to get the tiny short arm under the little tiny ledge. The reset spring just takes a bit of patience and long needle nose pliers I tried to use the ones I used on the 75 frame the 09 needs longer narrow plier to get in there because of less space. I also spent a bit of time using some 600 grit sand paper smoothing out the pins a bit to get the roughness off. Seriously though the hardest part is installing the damn decocker spring.
