I can only help you with number #2....
I've had mine about a month now and shot it several times (approx 500rd total).
Reliability has been good, although I have noted that if the mag is completely full (30rds), the first round won't always feed; the HP will catch on the feed ramp. Loading only 29rds works and feeds fine.
Accuracy off a rest is excellent, I've been able to keep all but 2 of 30 rounds in the 10 ring of a B27 target (~3") @25yds.
Offhand accuracy is very good, although the pistol is in the 4lb neighborhood loaded with a light and EoTech, which gets tiring holding out after a while. Rapid fire is extremely easy to control, and 30 rounds gives you a ample reserve. Magazine changes are smooth and quick. A stock and foregrip would really help stabilize the weapon and I may end up SBR'ing mine at some point.
Recoil is dampened by the mass, although it has a different recoil pulse than most Browning style locking mechanisms. Almost has a delayed recoil feel to it.
Cleaning is a bit more involved than your typical handgun, although it was easier than most rifles.
All in all it should make a nice home defense handgun.
