With the cylinder still closed and the muzzle still in a safe direction, take a firing grasp with your dominant hand. Cup the gun under the trigger guard with your support hand, and with the thumb of that hand, apply light pressure to the cylinder. Use about the same pressure you’d use to take your pulse at the wrist. This will effectively duplicate the cylinder drag of cartridge case heads against the frame at the rear of the cylinder window if the gun was loaded.

Now, slowly, roll the trigger back until the hammer falls. Hold the trigger back. With the thumb, wiggle the cylinder. If it is locked in place, then at least on that chamber, you have the solid lockup you want. If, however, this movement causes the cylinder to only now “tick” into place, it means that particular chamber would not have been in alignment with the bore when an actual shot was fired. Armorers call this effect a DCU, which stands for “doesn’t carry up.” You want to repeat this check for every chamber in the gun.
