Holster bolt. Can anyone help?

[Swizzle_r]

Hi guys I recently acquired an amomax  holster. I’d like to get a drop leg platform but I don’t know what or where to get a bolt/screw to fit. Can anyone help? Even measurements of the bolt/screw would be a big help. Sorry this is probably totally stupid question but I’m total noob!

If the holster you wish to mount to a drop leg is a "paddle style" holster which looks like what I've added below with the circle and teeth, then you can get something like what I run:
