I have a single drill Special Agent Pro pin, pin above ring & small balance hole on the thumb quadrant.  Not really trying to sell it, but w/right offer, I may part w/it.  I may have used it for an equivalant of 5 to 7 games tops.  I couldn't get it to do what I want w/my release.  I think the driller wanted me to change my release for the drill.  I won't go back to him, plus he was higher than the other guys I've had drill.

Just grip it & rip it!
