I have a CT on my S&W. Like you I don't use it at the range as much. IMO the range is where I hone my aiming skills down the iron sights. I do make sure my laser is true. That's not to say I don't do some practice with it. The reason I have a CT on it is for the times that aiming down the iron sights may not be plausible or should the situation require instant targeting, say from the hip. The CT is accurate to be able to draw point & hit your target from the hip but that requires you to fire upon immediate target acquisition. Also the laser may & I say "may" be an psychological deterrent to a situation once the BG's sees the red dot on his chest.
Different situations would require me to make the call as to what I use.
It's just another tool, but like any tool, you have to be proficient with it.
My gun is like an adult diaper, I wear it daily & no one has to know, until the day "crap happens"
