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. 1 http://cockedandlockedguns.com/wp-content/uploads/2015/04/IMG_28981.jpg http://cockedandlockedguns.com/wp-content/uploads/2015/04/IM... 2 http://assets.suredone.com/1928/media-photos/truglo131gt1y-1-truglo-131gt1y-tfo-tritium-fiber-optic-sight-glock-17-19-22-34-brite-yellow-rear.jpg http://assets.suredone.com/1928/media-photos/truglo131gt1y-1...
