You can see the crescent shaped tab fitting over the cylinder shaft. It also shows how the extractor rod is just a tad short of the full case length.
Forgot to mention; you can shoot .22 short, lr or buckshot (ratshot as some call it) ammo. All in all a great 'training gun' for new shooters too. It weighs in at 22 ounces.
As you can see; it's no longer than the blade on your average pocket knife
