I noticed the beam showing on the smoke from an indoor range session a couple weeks ago- first time shooting it indoors. Definately would bug other shooters in the lanes adjacent.
Kept me from wandering the muzzle around other lane's targets.
On my S&W 340, I check last night and the index finger can be lit up easily with my CT. I guess though, when unloaded, draw, present, and dryfire, it wasn't a problem for me. I feel I won't draw until I plan to shoot, and my finger is moving towards the double action trigger. But I did notice it. Good to know if drawn out of Bedside safe in the middle of the night with a sound. But when investigating a couple of sounds since, I have carried it to check doors in my strong hand light enough not to activate the laser anyways. Of couse if I did, my labrador would be chasing it around as I was looking for intruders
. I bought the laser pointer for $5 with the CT grips. My dog is crazy about it. I plan to laze the intruder and have my Heavy lap dog jump on their chest.
