Another vote for the Eagletac D25A clicky!

The pocket clip is very solidly screwed to the end of the tail, making for
“Deep carry”’ and the clip is extremely stiff and sturdy.
I sometimes have to use my hand to help manually spread the clip open just a
bit to clip it onto my pants— but I know it isn’t going anywhere.
Better yet— the switch is slightly recessed, and the switch boot is flush with the
tail tube— it is almost impossible to “accidentally activate”, no matter which carry mode.
My Zebralight is beautifully made— but the side switch has accidentally activated
on too many occasions……
