I got an email today regarding the LAS/TAC 2 that has the same footprint as the X300 lights and works with all my holsters, apparently the laser unit has been discontinued and TNVC has none left in inventory. Did any other sites carry this unit besides TNVC? Im not interested in their new $800 DBAL or any crimson trace units, and the X400 wont work with the dozen holsters I have that fit the X300 and the LAS/TAC 2.
