sorry guys a few beers and nodded off in front of the tv, and yes its a lightning, i've never shot a gun like it and I have shot a few springers, I've never had a problem with hold and can group pellets all day long at 25/30 yds with my own springers, if its hold sensitive I can't understand why it will group 3 or 4 shots then the group moves 3 or 4 inches. tried a few different pellets an some would'nt even group
