Well all of the ones I've handled have had some hair of side to side play in the cylinder at rest and lockup. Got informed at the range today that this isn't normal and signs of a GP100 needing tuning.
So are these things supposed to lock up like a vault or is some play within manufactured spec? I just thought this was normal lockup for the cylinder.
