There is no way that it can work properly in the MTAC
, because there is no space - no tunnel - for the laser module to travel. If you wore it for a while, the leather would mould around it, and when you went to draw the leather would be moulded around it. A CTAC
might work, if Comp-Tac made it specifically to fit the Crimson Trace grips.
For IWB carry, one of the Lasermax
products might suit a left-handed person better.
