Benelli M4 - Modlite Weapon Lights

Stupid question here:  what’s the reason for machining the tailcaps on your weapon light?  Do you do this because of a clearance issue, or to speed/improve access to the light control?

Mainly so keep the shroud from jamming my thumb during the recoil of 12 gauge. There is no clearance issue with the shroud.

So I finally bought a modlite to replace my cheap olight on my M4. There is only one "issue" and its not that big of a deal, but I would like to know if it happens to anyone else and how I can fix it. With my flashlight off, if I bring the bolt back, and send it forward, the force makes the light turn on for an extremely small fraction of a second. It does this probably 75% of the time whenever the bolt flies back forward. It does this both empty, and when live firing. As I said, this isn't a huge issue, since when it does this while firing the gun, it's not like it would give away my position or anything because the muzzle flash is brighter anyway. But for battery saving purposes, is there any way to stop the flickering on when shooting/sending the bolt forward? It is the modlite PLHv2 with modlite body and stock modlite clicky tailcap. I am thinking maybe there is a slightly better aftermarket tailcap that might fix it? I would like to keep a clicky tailcap that's momentary when not full click, if possible.

I run surefire tailcaps never had a problem.

That's weird. I would try a Surefire Z68 tailcap to see if it corrects the issue. Another option would be to contact Modlite and see what they say, perhaps the issue is with the head?
