Just as the subject says I'm looking for an owb in leather for a 365xl that can be used with a Holosun 507k. Does anyone have the Mitch Rosen that Sig sells? If so I would like to hear about that, and what your experience is with that using a Holosun 507 K rather than the Romeo zero. It appears that it may fit but the Holosun is just slightly larger than the Romeo Zero.
I can't speak to the optics side of it, but the Rosen holsters sold via SIG are his Express Line, which don't have the molding of his traditional line. That said, they are still very high quality holsters.
