Hello, I'm the inventor of the Speed Sights. I believe I know what's behind Gary's issue with the sights and wanted to offer a tip that might be helpful.
Speed Sights were designed to work in a whole different way than traditional sights. It may be that your well trained eyes are still "looking for" the pattern they are familiar with so it feels "unnatural" when you first try them out.
The Point to Point system that Speed Sights are based on eliminate the need to align this surface with that surface or to guess when the two gaps between notch and post may be lined up.
Another way to say it is don't be concerned about lining up the bases, just lock your focus on the tip of the front sight, your peripheral vision will lock in the pattern as soon as the points touch.
Sure, the bases need to be aligned, but that comes naturally by keeping focused on the front point and letting your peripheral vision get an automatic "pattern lock" on the triangles. Don't use the line up of the bases as the primary tool for checking alignment.
Just "Touch the points...pull the trigger", try to resist the impulse to look at the bases or lines.
Now, most folks experience Speed Sights as feeling natural and easier to use; the quotes on our "user experiences" link on the speedsights.com website are from real people.
We just got an email last week from a guy who has been using Speed Sights every weekend for the past year shooting IDPA and told us, "...these are by far the best sights I've ever shot with..."
But occasionally we hear from experienced users that their eyes are still "looking for" the familiar pattern of their previous sites, just like they have been trained so well to do.
Thanks for checking out the sights, I appreciate any comments as it helps to be able better explain the system to other folks thinking of trying it out.
Good luck on the range!
Don
