Big CT fan here. Have CT's for G26/27, G19/23, LCP, 1911, M&P9/40, Ruger SP101. Also had one on a XD40SC, but sold it along with the gun. Lasermax for G29/30. Not much of a fan of the LM. Don't like the blinking light and it has to be turned on without just grabbing the gun. CT's are ALOT brighter too. Out of the CT's, it was just made for the M&P. I use the medium backstrap on my M&P's and the CT is a medium grip. Don't care for them as much on my Glocks. But have used them quite a bit. The LCP uses a CT Laserguard. Not a fan of the LG, but it's all they offer for the LCP and I wouldn't own an LCP without one. I like them on a 1911, but the grips detrat in looks on a 1911 IMO, except for my RIA Compact, which is basiclly sightless. LOL!
