The point is to speculate with things that fit vs made up nonsense that is clearly untrue.

It looks like a full-size can and a subcompact to me. And I would know, because I own all those things and have used them in that configuration.

The problem I have is that anyone would PLAN on going in to a murder with no booster. Yes, it will likely work almost every time. But sometimes it won’t, and it will stovepipe, and the only way to fix it is to drop the mag out, clear, mag back in and rack.

I’m an expert, and I wouldn’t want to rely on that path.
