The Mark 45 is quite interesting to shoot.   Dry firing,  the trigger pull is off the scale to the  point that
you'll probably check to see that the crossbolt safety isn't engaged.  Load the piece with a full magazine
and start firing and you'll see how well that trigger actually works.  A 30 round magazine will empty out
in a flash and keep them all in a silhouette target at 50 yards.  Aimed fire at a paper plate will get you hit
after hit at a hundred yards, although you can almost smoke a cigerette waiting for that big .45FMJ bullet
to get down range.  

The Mark45 doesn't require a lot of maintenance.  The tolerances in the stamped square steel receiver
and the slightly modified Thompson SMG magazines make for a very realiable firearm.    The stamped
steel peep sight is adjustable for windage by a large screw and elevation by bending it up or down.  The
fins are somewhat functional, but the muzzle brake is strictly ornamental.  It's removeable by loosening
the two set screws, but looks very odd without it and you loose your front sight.  This weapon was also
manufactured under the name Commando Arms Mark45.

   

     The buttstock comes off easily
     after removing the two large
     phillips head mounting screws
     from underneath and is still
     fully functional and legal.  
     Shown here is the pistol version
     with the buttstock absent.  With
     the short barrel adding the stock
     would violate Federal law so the
     back of the pistols receiver has
     been modified accordingly.
