The factory grip for the SP101 looks great, but it's too small even for somebody with small hands, and it's not that comfortable either.
This Hogue grip looks good too, but it's way more comfortable, fits my hand way better even though it's small also but bigger than the factory grip. And it's still small enough for conceal carry.
This grip improved my target shooting a lot!
It's comfortable, looks good, it's good quality, and it's not made in china!
