RMR on one of my Glock 19s
Truglo (tritium) sights on my other 19 and my 26

I recommend you shoot matches with whatever you chose to carry. Find out what works well for you.

My experience is that lasers are slower than iron sights. The RMR is slow at first, but you get fast with it. Lasers have you chasing the dot. Your mileage may vary.
