Sig 365 with holosun 407k - SIG SAUER X-RAY3 Day/Night Sight Set

Purchased these to replace factory sights as they did not co-witness well after adding a Holsun 407k. I was very pleased they arrived within a few days. Super easy to install using sight pusher (I did remove the 407 out of abundance of caution not to damage it). Perfect co-witness now and quick sight acquisition. Good Sig quality however, I was disappointed that the sights in low light and dark conditions, are not as bright as I thought they would be. Overall, very pleased with purchase and as always Optics Planet makes purchasing affordable, easy and reliable.
