Tried both on a Ruger LCP and ended up with the CT simply because it was more natural, almost instinctive to the grip of the weapon. Guess what I'm saying is, I didn't have to think, even for a second with the CT.
I've owned CT an shot lasermax, have a few friends that have the laser max's.
I don't like the idea of changing my factory springs to something by company that doesn't build guns. Shot one in a friends G19 and it didnt work consistently. One of the ONLY times I've seen a Glock not work consistently. Its also nice to be activated just by gripping an having the ability to adjust to where you need it.
