There are improvements to be had in pistol sites that don't involve battery powered gimmicks. The trapezoid sights on Steyr M pistols for example. I rented one from my local range and it works well for new shooters.
Came here to say this. The Steyr Triangle front sight/Trapezoid rear sight is a really great improvement. Actually, the weapon itself is pretty much a work of art. I've had the 9mm and the .40 S&W versions, and they are my favorite shooting pistols of all time. Very low bore axis helps with aiming and recoil. It's technically a double action firing mechanism, but the trigger is crisp with a travel almost as short as a single action. Not at all spongy like cough some other striker fired polymer handguns.un-cough
I know this discussion is really about sites, but after all the off-tpoic-ness we've had so far, I don't really feel bad derailing a little to talk about how much better this handgun is than pretty much any other. For reasons including the sights.
I found the length of the channel in between the rear sights makes a large difference for me in accuracy - compare [1] and [2]. The longer sight nearly eliminates (or at least makes the errors more obvious) the issues being discussed at the end of the article. By having a long sight you are forced to align the front closer to the center - there is almost no gaps between the left-gap-front-gap-right because the length of the sight occludes the front entirely if not aligned.
Some stock sights are now being shipped with long rear aperture.
This may make target acquisition take longer - I would be curious how professional and competition shooters feel about the difference.
