0sprey---I have the Doctor Optic red dot on my HK Tactical, it works great for an old fart like me. I thought I had their website bookmarked but I can't seem to find it. Anyway many mounts are available & you can get one that will allow you to mount the sight to a Weaver base. I think this sight would work great on a Mini, keep us informed.
Good luck
