Never shot the SP01 but my Matte Stainless is my most accurate double stack pistol. On its heals, however is the Beretta 96A1 in .40S&W which has a much better trigger reset. It is a keeper and more versatile, since a simple barrel swap allows for shooting 9mm at the range. I take it a step further and keep the 9mm barrel with its own locking block and use dedicated 9mm mags of a stainless variety for a sort of color code.
Lurking the Beretta forum recently I discovered a G conversion for the FS now exists (decock only, no safety). I don't need it; the only thing I changed on the 96A1 is the hammer spring to the "D" spring. What really surprised me is my sister (small hands) couldn't hit the broad side of a barn with my prized CZ75 Matte Stainless, but she.rang the gong with ease using the 96A1 in .40. Go figure!
