1. The revolver can somehow be opened and unloaded one-handed without damaging the...hinge?...that swings it out.
2. The person then shoves in what appears to be a disposable cylinder of bullets.
3. After that, the revolver is then flipped shut, which should also damage the hinge, but apparently doesn't.

I swear, there should be a major industry in scavenging the brass and the disposable cylinders from an area.
