I'm a fan of this ct laser. here's the good, bad and ugly - Crimson Trace Springfield Hellcat CTC Laserguard Green Laser

As of now, I have lasers on 7 out of 9 handguns. I spent an hour this week at my range, doping this laser on my new Hellcat. I look at it this way. I'm a decent shot. But I'm also getting older. Simply by doping the laser, I have a huge advantage if I ever heaven forbid....need one. As long as that bright green laser light is visible on a target downrange within normal range limits, I can most likely kill it on my 1st shot....without taking the time necessary to establish a good sight picture with good sight alignment. Think about that for a minute. That's going to be a lot quicker than someone sighting in on me. CT has great tech That's easy to deploy. And if I want to practice iron sights, I can just move the switch to off. Expensive compared to other laser sights but worth it imo. The ONLY downside is that none of the holster makers have supported this rig yet, so a belly band is the only option for the moment.
