Define consistent.
Also, with my .380 I have issues keeping tight groupings, even at 25 yards. Obviously, I'm not a pro, but I'd ask to see some proof. That's really tough to do.
With a competition-grade 5" 9mm (as in, practical shooting, not a bullseye gun) I can shoot maybe a soccer ball sized group at 25m.
Using the previous description of a 'world class' competitive shooter, like an Eric Grauffel or a Ben Stoeger, I think maybe they could do baseball or softball-sized. Of course, part of their strength is being able to whiz around a corner and do a double tap without even thinking, with the goal of hitting an area that is something like 12"x6"...and there's a reason they use such a 'generous' target, and not something absurd that no amount of training can condition them to hit consistently. Practical handgunning makes the conditions harder, 'cause if it was down to the mechanical accuracy of the gun, they'd either all be tying each other [with groups bigger than a quarter], or it would be a technology race.
What's nice is that it's easy to pick out bullshit when it comes to claims of shooting prowess. Why? 'Cause the people who say this stuff don't realize how entirely outside the realm of possibility their claims actually are. It's not 'ooh, I can hit a watermelon at 300 yards with an iron sighted AR'...that's doable. Fuckin' hard, but it can be done, and it can be repeated. No, it's 'I can hit a tic-tac at 100 yards with a .32 pocket pistol' or some shit.
