[Brandy]

I have CT laser grips on my Airweight and 329 because I'm old and can't see the sights and the target, especially in low light.
Insofar as blocking the laser with your trigger finger....well once my gun clears the holster, my finger is on the trigger as:
1. It hard to fire a double action revolver "accidently".
2. If it's drawn, that means there is probably going to be shooting done.
3. You leave the on/off switch "on" whenever carried and your natural gripping of the gun activates the laser switch.

I don't subscribe to the UK's "Stop armed police drop your weapon" mindset or worry about range safety when dealing with a thug or bear.

CT DVD is a must have as it shows many situations where conventional sights are either useless or force you to expose yourself unecessarily.

I'm just waiting for the 300 yard daylight laser, then I'll sell all my riflescopes.
