What do you like and prefer and why? For a defensive pistol, not target/range gun. I had always used a 3-dot tritium setup, but with my Nighthawk pistols went with Heinie straight eight 2-dot setups, just to try something different. Personally, I think that I pick up the 3 dot picture faster than a 2 dot. I am looking at options to swap rear sights to allow that... I tried and liked the 10-8 rear and front dot setup also. For me I think I prefer 3 dot, but close second would be a blank rear and single dot front. What do you all prefer?
