I wonder if the gun jammed up because of weak grip tbh. Ever shot a .45 and had it jam? It’s most likely because the gun is too powerful for your grip - the slide doesn’t move back and forth properly and then you have to clear the jam like dude does in the video.
Anyway, reason for jamming aside, dude was committed/practiced, but I don’t think he’s ‘catching casings’ like others initially suggested. This wasn’t that smooth.
I can second the Concept 2. I’ve had mine a few years and it’s still a solid workout.
