I love the dawson precision fiberoptic tritium sights, they glow in the dark, are highly visible in the day and are finer, so you can shoot more accurately.
The sight spedometer is the way to go, its just the same with hunting, think of every shot and make sure you are on target first, not hitting costs more time anyways.
I always check every round expecially for competition but once or twice missed that one that really messes up the whole match. But still am a big fan of reloading, I had some factory ammo I shot that had the primer in backwards, everyone makes mistakes.
I did the exact same thing and just decided not to turn on the dot to see and was surprised to see that I did just fine, your brain just gets used the the right position, although the dot is good insurance for hard targets.
