I owned a Mini "V3" and really could not stand the magnetic return of the trigger. It was too light for me. I used a more powerful magnet to try and help, but I don't think anything short of a trigger upgrade (the one with the return spring) would have made it better. The trigger on mine had side to side movement too. It was sloppy to use. It is however, a simple marker to care for, and I really wouldn't see what more anyone would need in a marker over what the Mini provides. I liked the Axe more because it fit a bit better in my hands, and the micro switch was what I needed. I also liked the push button bolt removal. But thaaaaaaaaats just me.
