Sadly, it seems the only bullseye competitions are only for 45 1911’s and 22’s. I would LOVE if there were a slowfire, accuracy based type of pistol competition. If you want a gun you can use for IDPA, USPSA, Steel Challenge, and GSSF, you’d be hard pressed to find a better all-around gun than the G17. Another fine choice is the 34, but it does limit you in some classes in GSSF. Top level competitors use both with good success.
