Wilson Slim Line Grips are laminated from beautiful Cocobolo wood or Diamondwood with only 1/3 the thickness of standard grips.  The result is an overall grip profile which is approximately the width of your 1911 slide.  Now that's thin!  These grips are actually thinner than the stock grip screw bushing, thus requiring special grip screw bushings and grip screws which are provided with each set of grips.  For the ultimate in concealed carry or for those that simply prefer a narrow grip, you've got to try these grips.  Not available for Norinco 1911.
