IMO less important than the gadgets is figuring out what to focus on while you dry fire. Pull the trigger, rack slide repeat.. that's just going to train bad habits. You're giving up all of the fundamentals after every trigger press. You want to maintain them through an entire magazine.
Focus on that good stance.. stiff wrist.. good grip, good sight picture. Hold that for a bit Pull the trigger without moving the sight while holding that. Hold your stance wrists, grip, and sights for another 10 seconds after that. Maybe work the dead trigger. Do that 10-20 times a day for a month.. results.
Until I figured that much out I could hit anything I wanted to with a laser cartridge but put live ammo in the gun and it'd show me something I was doing wrong.
