Everyone is waiting on the Modlite PL350 and, when it does finally drop, PHLSTER will have you covered on holsters. They are already in production on the Floodlight for the PL350 and will have the holsters available the moment the light itself is released.
If you aren’t familiar with the Floodlight series of holsters, you should be. They are holsters that are designed around the light instead of any one specific handgun. The end result is a holster that fits almost any handgun as long as the specified light is attached.
