I always recommend you shoot it until you get good with it, maybe shoot a few IDPA matches, and then decide what/if modifications you want to make. Action shooting under some simulated pressure is different than just playing with the trigger or casual plinking and you may change your mind with experience--or not.
If you plan any competition at all, the changing of the externally visible trigger disqualifies you from SSP or Production and puts you in with the modified divisions.
