On a double action revolver, with the thumb and index finger of your left hand holding the cylinder with slight pressure as to keep it from moving, pull the trigger with your right index finger very slowly as you watch for the locking bolt to engage the locking notch in the cylinder. The bolt should "drop" into the notch just before the hammer falls (with that slight pressure restricting the turning of the cylinder).
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
