Fred, Remove the magazine from the pistol by pushing the button behind the trigger on the left side..the magazine will likely fall down at least enough to be withdrawn easily. Look to see if there is any ammunition in the magazine.
The pistol is on safe according to the photo's you show. It should be safe to remove the magazine.
Take the pistol outside to soft ground..point it at the ground in your left hand and push the safety forward to the fire position. Grasp the toggle knobs on the top of the pistol and pull up and back. Remember to keep your finger OUT of the trigger guard. When you pull up and back on the toggle the round in the chamber will eject and likely lock the toggle in the rearward position making the weapon safe.
