IMHO, they oversized the grip, very similar to the SR9c,....the thin profile is a plus, but the the "oversize grip" especially in a compact to get every rd. of capacity possible within a design parameters, missed slightly....for a true compact.
The PF-9 keeps the narrow profile of the slide all the way to the grip, and been around. I'm not bashing the Ruger by any means, it is a personal choice.
My 6904, an older S&W compact, managed to keep the proportions right and cut it down to 12rds.
