surefire SR07 on mu new 620v

Hi all so I got my new 620v in and want to put a SR07 on it and my 620v came with a tail cap push on /off and a UE07 . But I tried once and don’t want to break anything the ST plug that goes in the tail cap won’t come out slide out or whatever am I doing something wrong or is what came with my 620v not a UE07 but it looks like one . Any help before I break something I’m not suppose to thx’s all…

I got it out I guess since it was brand new it was hard to pull out the plug… How does everyrone like the SR07 on the 12oclock rail …???

If you shoot with thumb on top than put it on top.

If you shoot with VFG then put it on side.

I run mine @ 6 o’clock


Still debating left or right side mounting…
