In IDPA, you would be competing with 9mm minor. So unless you reload, you are giving up a lot in recoil for the same 9mm hole. I have shot mine in IDPA with full power ammo, just as practice, but if competing, 9mm, 357sig, 40, all go into the same div PF wise. I can reload 40 minor to the same recoil level as 9mm minor & a slightly bigger hole.
