Torx size for trigger shoe?

[FLChinook]

Anyone know what size torx screw would be on a trigger shoe? It's smaller than my smallest allen. I understand the #8 torx is 0.090" tip to tip and that's bigger than my smallest allen. So I assume the size I need is somewhere #4 to #6...

Thanks

As more and more things have Torx screws I suggest you get a set of the smallest sizes .They come a whole lot smaller than you think LOL !!
