This would be a 5 if it were 3/16" longer in the back and had rounded corners. In stock form the corners seem to poke your palm and it is a bit slick.
I fixed the corners by sanding them down and buffing the plastic back out. I am 99% satisfied now. If it were just a were bit longer they would be awesome.
However, these are for a Concealed Carry gun so really the do their job as intended. I'm super happy with these!!!
