TS,

Many shooters are dumping tape switches on lights for push buttons, especially if the tape switch is the only way to turn the light on. Tape switches are not as reliable as buttons as a general rule. There is also the factor of white light AD's and the need to turn the light to constant on.

I use a surefire classic 6V tac light with a push button cap. If I get into a deliberate clearing phase I can go constant on which allows me to run the rifle with one hand while I open foot lockers, over turn furnature, or whatever.

I had to clear the back of a military truck (5-ton) once when I was still running a tape switch and when I grabbed the tail gate to steady myself while standing on my buddy's back I could not keep my light turned on.

I agree that VFG's are great for securing tape switches but I only run my laser switch on them now (and I carry an extra laser switch in my arm pocket).

The problem with button lights is that they are normally offset to the left or right of bore and I prefer to keep my "under gun light" under my gun. I have a front grip that actually houses my light and the button protrudes out of the back end of the grip. my light and grip do not fight for 6 Oclock rail space and my light stays under my rifle to minimize shadows thrown by my barrel/rail blocking my light.

Here is a pic of an old M-4A1 set up that I was running several years ago. I run the same grip on my assault rifle now.
