My experience with these pistol mounted lights convinced me that
as a generalisation,
for my old tired LAZERED eye balls any way
INSIDE a room,
an LED is a better light ...
brighter, cooler, whiter spectrum, longer lasting, more durable.
However,
out in the brush,
where the target may be obscured by foilage,
for me an LED does NOT penetrate as well as the old incandescent bulbs.
With the LEDs, in brush,
you get more of a 2D view, rather than a 3D view.
That being said, all my EDC hand held flashlights are CREE Q5 LEDS. These are great. Last week, while walking the dog and shining one of my EDC flash lights on him to illuminate him from oncoming traffic, I had a car stop for me, around a switchback, because he thought there was another vehicle coming around the tight corner.
He rolled down his window to tell me this, and could not believe my little pocket flash light could put out that much of a beam.
I use an old incandescent Streamlight M3 on my Glock. Personally, I much prefer the quick release / snap on mount of this model over the types that rely on tightening a screw, or permanently mounting the light to the weapon. I also have practiced the Harries method of holding a pistol and a hand held flashlight at the same time.
IMHO, a weapon light should be a SUPPLEMENT to your EDC flashlight. If all you have is a weapon mounted light, and it doesn't come off and on quickly and easily,
you could easily get in the rather bad habit of illuminating things that go bump in the night,
WITH A POSSIBLY LOADED FIREARM aimed at ...
whatever?
Not every situation that calls for light, calls for a loaded firearm pointed that way as well,
and LEGALLY,
pointing a flash light at some one is much different than pointing a weapon.
free opinions on the internet are often worth much less than you paid for them,
