I have Crimson Trace grips on my G19 but am always interested in reading about the other brands. The thing that steered me toward the CT grips was the fact that there is no cumbersome on/off switch and, since the laser resides on the grip rather than being located near the muzzle, I don't have to worry about powder residue fouling up the lens. The disadvantage is that they fatten up the grip a bit. To me it's not a big problem, but it might be for someone who thinks the Glock grip is already too wide.
I've heard positive and negative things about the Lasermax (mostly positive though) and the TLR-2 looks like a neat gadget. Strangely enough, I haven't really read anything about the Glock brand unit.
Quick,
I have a lasermax on my Glock 22 and I typically keep the TLR-2 on my M&P40.
They each have their advantages and disadvantages.
As far as the laser goes, I prefer the laser on the Streamlight 100% over the Lasermax laser. The lasermax pulses, which can be good and/or bad. I've found it very annoying in low/no-light. However in semi-bright light, the pulse has helped me pick up the laser a little quicker, but typically in these lighting conditions the laser is worthless.
The TLR-2 has a bright solid laser that I really like.
The activation of either of the lasers is really simple (at least the way the glock is actuated, as Lasermax for 1911s, Sigs, etc are a little different).
The rocker switch of the TLR-2 is naturally positioned for those of us who keep our fingers outside of the trigger guard.
On my Glock, the Slide Release (takedown bar) can be pushed in from either side to activate the laser. Again, for me, this is easily actuated by the index finger.
Of course, the best thing about the lasermax is that it doesn't change the exterior of the gun, so all holsters and other gear work with it perfectly. I see this as being the greatest advantage to the Lasermax.
I don't have any guns with the CT grips installed. I'm a lefty and when experimenting with them in the past, my thumbs seem to block the beam when I grip high. But I do really like the models with the pressure switch built into the palm swell.
That's my $.02.
