I have a 66-2 three-inch that I like quite a bit.
slamfire, looking at the case rims DOES NOT confirm that the gun is loaded. It only confirms that there are brass casing in the gun. Open the cylinder, confirm that there are live cartridges in the gun. Also, opening the cylinder gives you an opportunity to confirm that you have no high primers. I generally open cylinder, then close cylinder until the locking center pin in the ejector rides in past the ramp in the recoil shield. I then rotate the cylinder 360 degrees so that all six cartridges rotate past the 12 o'clock position. This confirms that all six primers are properly seated and will not tie up the gun. I then close the cylinder and holster the gun. When you CCW a revolver, you develop these little fail safe procedures.
