We've covered the new green lasergrips for the LCR and LCRx previously, but a traditional red variant is also available. The LCR is pretty firmly established as a pocket or otherwise concealed revolver, however, the Ruger LCRx with three-inch barrel variant isn't quite as portable.
While still possible to carry in certain pockets, the larger LCRx is more likely to be carried on a belt either inside- or outside-the-waistband. As less concealability is needed, having a full firing grip on the small, light revolver is possible while still keeping the overall size minimal.
Crimson Trace made full use of this increase to produce a set of lasergrips that not only produce a bright laser dot, but also allow all three fingers of the strong hand to find purchase on the polymer and rubber grip. Naturally, these full-size grips will fit on the smaller LCRs as well, but will add bulk at the grip and therefore make the diminutive revolver harder to conceal.
