Then what you need is this combo:
Allchin Ruger C-More mount
C-More Slide Ride or Railway
Black Dog HMK-01 Holster
The Allchin mount will place the C-More as low as possible, unless you get one of my 90 degree laydown mounts (not available to public yet). the holster will perfectly fit a 22/45 or Mk series with the Allchin rail and the optic as long as you don't have a VQ slip on comp on the barrel. If you have a TS Pac-lite upper and their screw on comp that will fit ( Tactical Solutions sells the holster).
The holster fits a Buckmark with the Allchin rail and C-More also.
Does anyone know if the C-More railway will fit on the stock rail that comes with the Ruger Mark III? If not, what mount do I need?
Thanx!
