With gentle probing the opening should be located. You will feel the gun slide
forward until it contacts the second cervical ring. Maintain gentle but steady
forward pressure on the gun and slide your thumb and forefingers just in front
of the gun tip and re-grasp the cervix. Because the cervix is composed of dense
connective tissue and muscle, it is difficult to clearly distinguish the gun tip
when it is located within this structure. However, you can determine the approximate
location by bending the cervix. Using the flexibility of your wrist, twist and
bend the cervix until you feel the second ring slide over the gun tip. Repeat
the process until all the rings have been passed over the gun tip. In some cases, it
may be necessary to bend the cervix at a 90º angle to clear the cervical folds.
Remember,you are placing the cervix over the gun, not the gun through the cervix.
