My Mako is a year old now. Even with the CT dot. (That still works fine on the original battery) it's a tack driver with that dot. Long shots are not out of the question with this gun. I agree with you, a dot is the way to go on this gun.My wife has and carries a Mako
Here are my thoughts:
The rail isn't much of a rail.
It's more cosmetic.
You can probably find a laser to fit it, but then you probably aren't going to find a holster to accommodate it.
If the irons aren't enough, I would buy a red dot optic and call it a day.
With a dot, my wife can ring a steel mini torso plate at 100 yards.
It's made for a dot.
