XS Glock 42 / 43 Night Sight



The Glock 42/43 Night Sights set by XS Sight Systems offers a unique option of sighting that is not common to the target or precision shooting world, but more designed for the purpose of self-defense in high stress situations.

XS Big Dot Sight for Glock 43 and 42

When your life, or the lives of others are at stake you simply don't have time to put those pin-point sights where they need to be. The XS Sight Systems Glock 42/43 Defensive Express Tritium Sight boasts a large circle and tritium insert for the front sight which is perfectly suited for low light conditions and fast acquisition, while providing an easy to use vertical white line, low profile, snag free rear sight. This combination allows you to easily acquire and quickly place shots on target by using the 'lolli-pop method' of aiming by placing the circular front sight on top of the vertical line rear sight, using your sights to create an image of a lolli-pop.

While this doesn't assist with 'surgical accuracy' like other sights may provide, it does minimize the amount of thought you need to use to aim or the muscle-memory habit of making fine adjustments during high stress shooting situations where short distances and fast follow-up shots are a factor. You place the XS Sight Systems Big Dot circular Glock 42/43 tritium front sight on target and squeeze the trigger. It's that simple.
