I run a Viridian R5 instant-on green laser on my XD-s, but they don't make one yet for the Hellcat. Currently I have an O-light Baldr Mini green laser/tac light combo on my Hellcat, but it's bulky. Works nice, love the rechargeable feature, but for EDC it's just a big square hunk of aluminum on the nose of the pistol. I found ArmaLaser is making a grip-switched green laser, very compact, for the Hellcat but I'm not familiar with the brand. Anyone have experience with them? The model is TR-26, looks like they make green and red.
