I would recommend at least buying some Back up sights and training with those first. One should always have iron sights on a firearm IMO. You should be good at shooting irons, altering windage/elevation/etc, before you spend $500 on a battery powered optic.

"Meet me at the bus station and hold a sign that reads: 'Today is the first day of the rest of your life.'"
But the old me met me with a sign that read: "Welcome back."
