Unless he's got one of the just out "tacticals" if its a 5" gun it should be a standard plug and plunger setup. And if the brass is launching into orbit get a stronger spring. 16lbs is standard and functioned well, but as a reloader when the empties start landing in the weeds its time for a replacement. I've a Wolff 18.5 lb spring in mine and it lays the empties in a nice pile about 3' diameter 3' right and 4' back, lose very little brass when shooting it which helps make it a favorite.
If it its the 4" or 3.5" models the brass will fly a lot farther and you'll have to live with it. You can try a stonger spring, but in my experience while it might reduce the distance the empties fly, it seems to randomize the direction making them even harder to find with some percentage even going forward.
If you replace the spring in the 4" or 3.5" models, make sure its not too long and the slide hits the impact surface before all the spring coils touch or you'll break the reverse plug in fairly short order.
If you don't reload I'd not worry about it.
