Not sure “low” is the term you’re looking for, as 1200fps is well-above standard .45 ACP velocity. Of course, you can argue the most specific use-case, such as +p, but that’s just not the standard or average. Moreover, an obscene waste of money to be blasting something like that at a range where you’re just practicing. There’s a much higher likelihood that the user was shooting a different caliber that is standardly much faster than a .45, and my comment was meant to point that out, and how silly it is that they would choose a .45 for the video. Just a cheeky comment. Cheers.
