Sweet! For my big hands, the aluminum grips were just too thin, and so I ordered the rubber grips which are just perfect for me.
FWIW, the SP-01 is the perfect range pistol. Shoots 9mm (cheap), recoils like a .22LR, and is perfectly ergonomic. The only bad thing is that it is an ammo hog, i.e., with the big magazine and nominal recoil you can easily go through 400-500 rounds and still be wanting to shoot. Shoot the paper targets, shoot the steels, shoot the paper targets so more, shoot the steels some more, repeat . . . . . way too easy to burn through $100 of ammo in an hour.
