Excellent sights for quick shooting, defensive use - XS Sight Systems DXT2 Big Dot Night Sight - Glock

I have tritium night sights on all of my auto loading pistols, defensive rifles and shotgun. These sights are from various high quality OEMs. I use XS Big Dot night sights on all of my handguns that support them- as the large front sight dot makes quick target acquisition easy. I like these Glock DXT2 sights the best out of all of the designs. Excellent products. These are easy to install and comes with all components. However, there are no instructions provided in these kits but an excellent XS provided video on YouTube is available if one has online access.
