I received Gunfighter III with MCG grip with desktop base. What I noticed, when I put right hand on polished metal rim around metal base I feel constant electric shock (only where skin is delicate, cant feel anything when touching it with fingers or palm). Did anyone of you experienced similar feeling?

Do you have multimeter? Please check where the electricity comes from.
And check the surface of PCBs, cables. See if any damage.

Also check this cable.

...this might be the reason. Ugh!

A few Cables have Contact with the Housing ( Base ) ...

Well, I would say: You need a new Connector, or some Patience and Skill in soldering. ; p
