Xs big dot sights - XS Sight Systems DXT Big Dot Sight - Sig Sauer

Simple, fast acquisition sights that work really well. Pretty simple to install too. The tritium glows well in low-light conditions and re-aligning the front sight during rapid fire is a breeze thanks to the rear sight’s shallow v-notch and front sight’s big dot. Doesn’t snag on anything either so it won’t rip a hole in your shirt if you conceal carry.
