The only issue I have with the 1311 (based upon where I carry it in the truck) is it's length.  The 911 just works better for the place I carry it. You know, now that I think of it the 1311 MIGHT fit on the seat railings, between the seat and the tranny tunnel!  And If MB would make me a baldric strap for it......  

  Might have to give this some serious thought.
