If you use a suppressor, this is a great holster and light combo for different guns. The light just slides on to my M&P or my 1911, and I can holster either suppressed. The holster retention is good enough for run and gun action. It sits at a good height on the belt line. I would like to see it pushed away from the leg just a bit as it can mark up your pants from the hot suppressor touching during odd movements. Just standing that doesn't happen. Over all it's well built and works great!
Instead of buying owb holsters for all the different pistols I have... A rail and an x300 is all I need. Has worked on every glock generation I have, my cz75, my 97, and my p320!
