Vertical velocity is 170 ft/sec, and a 2G pullout would subtract 32 fps from that every second. Let's say 6 seconds, during which you would lose quite a bit less than 1,000 feet. Doesn't sound as if pulling out of a 25-degree glide at 250 knots would take that much room. At low altitude it should be possible to pull 2G without risk of a secondary stall. The point is, despite its high vertical velocity the airplane is not descending that steeply.
