Seems like a good idea - Meprolight FT Bullseye Tritium Self-Illuminated Rear Pistol Night Sight

I have purchased two of these sights now. I put one of the sights on a Glock 19, and the other on a Glock 43. I then took the two handguns and a Glock 19 with traditional meprolight night sights to the range. After 500 rounds, I found the sights neither faster nor more accurate. I believe they may be able to be as accurate as traditional sights, but it will require more practice behind the sights. The problem seems to be that it takes a slightly different process to get the dot aligned in the circle. I found that shooting with both eyes open was also more difficult with the sights. I seemed to have something akin to parallax happening with both eyes open. With practice these sights will work, but unless you convert all of your handguns to this style of sight, you may have difficulty switching between styles. My choice will be traditional night sights.
