Lighting is HUGE, mostly because indoor ranges lights hit the rear sight but leave the front sight in the gloom. You'll do far better on an outdoor range. In fact, most pistol ranges are built with a shed roof to cover the shooters while the targets are out in the light, which is pretty much the ideal setup for shooting small groups at long range.
