I’ve read stories of missing parts like that, where were the inspector’s minds? At least they made it right and quick. That mag release is in a weird spot, for sure. That M22A looks like an old object of my lust, the old M41 target, always wanted one but was WAY above my pay grade back in the day. Did get a 2nd model Detective Special that was nice, even had the gold lettering on the barrel. Scored it used for $85 at the gun shop I worked at back in 1975. He had another one but it was kinda beat up for $60 but I wanted the nicer one. Sigh, long gone...
That model 22A came with a test fired .22LR case in a plastic bag. Some requirement from some states I assume. I wondered how they didn’t notice when they fired it but then remembered I had fired it several times before it jammed.
I have owned a couple of Beretta Minx in .22 short. They had no extractor as part of the design. The tip up barrel allowed you to remove rounds from the chamber. It was extremely reliable so an extractor might not be absolutely necessary in calibers with very short cases.
Of course there has to be some way to remove unfired rounds from the chamber.
