90% of your practice is dry fire. The greatest skill to master is sight alignment on the draw. That is best done with an empty gun and a boring amount of reps. I shoot 1000s of rounds a year and would shoot more if the cost of ammo wasn't so damn high. Unless you're shooting on a Ipsc or uspsa type course shooting on an lane does very little. Most ranges don't allow rapid fire, or drawing from a holster.
