My personal experience with red and green lasers is they can contribute significantly to the precision of the point of impact with slow, aimed fire, especially with guns that otherwise have a very short sight radius and poor sights (j frame). Both red and green lasers are practically unusable in bright sunlight. And both red and green slow down the process of acquiring sight picture on the target and extend the time to the shot. I have been impressed with the quality, materials, and construction of the Crimson Trace products, irrespective of the laser -- in other words, they're good grips besides having a good laser.
My observation is that lasers on handguns are out with shooters. And on carbines they remain desirable primarily as IR lasers with teams that use NV because the whole team can see the dot and nobody else. On handguns, I just don't see anyone serious about shooting using them or paying any attention to them. Compare them to miniature red dot sights, and it's pretty obvious they've been relegated to gimick status. Another thing that's telling is there are almost no training academies, classes, or courses with laser curriculum. If something fundamentally changes the process of how you aim the gun, and there's no training that uses it, I conclude it's not being taken seriously. Red dots, on the other hand, do not so fundamentally change how aiming is done. They could be used with the same training curriculum as existing classes. But red-dot specific classes are also popular in many of the training academies.
The exception is Smith & Wesson. They (AOBC) bought Crimson Trace and they're not going to let it go to waste. I see they are aggressively marketing guns with lasers, especially their most popular Shields and j-frames. They also paid (sponsored) Gunsite to offer a one-time Crimson Trace class (coming in November). I believe they see oem lasers as a value-add for which they can persuade some customers to pay more for.
