Olight M30's strike/shroud style tailcap for M20?

[jjj0309]

A simple question; Is there any way to get M30's strike/shroud style tailcap for M20/M21?
Original smooth tailcap for M20 is very decent though but me myself, who felt greatly pleased from Surefire E2DL's tailcap, I still wanna try out more secure feeling taillcap. I've searched through web but could only found smooth tailcap for M30, not the shroud tailcap for M20/M21.
These kind of tailcaps somehow feel more secured & stable when I pocket-carrying lights.

I don't think you can buy the tail cap you are talking about unless you buy the whole M30 light. The smooth version tail cap was offered because of complaints about fitting the M30 in a holster on a duty belt with the flared tail cap. If you do find a flared tail cap, it needs to be used with a side switch model M20s.
