The Apex trigger is the mod most will suggest. Before doing so consider this. If it's your daily concealed carry and, (God forbid), you're forced to defend yourself, be aware that if you wind up in court, Mr. Bad Guy's lawyer will use it against you. Same with your choice of ammo. You'll be portrayed as someone who couldn't wait to shoot somebody. Just sayin.
Never argue with an idiot in public. People passing by won't know which one of you is the idiot.
