Shooting lead bullets in your pistol (Baby Eagle), would be a no-no for the same reason as the Glock. According to the Magnum Research website, the Baby Eagles all have polygonal rifling. Polygonal rifling doesn't have conventional lands and grooves to grip the bullet. Instead, like the name implys, the bore is shaped like a polygon. Polygonal rifling has plenty of "grip" on harder jacketed bullets, but not on the much softer lead, with will tend to wipe off in the throat of the barrel. This causes a rapid buildup of lead fouling, often leading to excessive pressures and even a bore obstruction related structural failure of the weapon.

So, no, shooting lead in your pistol would be a bad idea. I know that some companies offer aftermarket drop-in barrels for the Glocks that have standard rifling, and many people buy them just to shoot cheaper case bullets, then swap the polygonal stock barrel back in for jacketed bullets. This might be an option (if aftermarket bbls are available for the Eagle) if you want to regularly shoot lead, but if it's a one time thing, it's probably not worth it.
