I'm not a competetive shooter by any means and don't plan to be, but I find the laser to be an excellent aid to dry fire practice, especially for trigger control. I've recently added an RMR to my carry pistol and it serves the same function for dry fire, more or less, the laser works better at 20+ yards because it shows the trigger/grip control wobble at distance better than the RMR. My laser is rail mounted, BTW, and that's how I carry it. Sent from my Pixel 2 using Tapatalk
