Great sd sight - XS Sight Systems DXT Big Dot Sight - Sig Sauer

Great self and home defense night sight! The sights are not really ideal for target or range work much beyond 15 yards, but for up close this system is very quick and efficient. It will take a little ammo to get used to the system if you use a typical 6 o'clock target hold, as the front sight of the XS Big Dot will pretty much cover the target point of aim for best results. The "Dot the I" of these sights is much faster for me than the typical 3 dot sight set up and the larger white ring surrounding the tritium vial is a big plus for this baby boomer's eyes. Installation is straightforward with good instructions (downloaded mine) if you are doing it yourself and if you are, take your time. Best home defense night sights IMHO!
