No fear of taking the plunge on this shotgun....awesome firearm!
Bought a lightly used 3.5" gray shadow a couple years ago and it too digests every load I've used,, Fed TopGun is the lightest tried.
Have read of some guys having issue with the newer "black shadow" model and the cost savings "lack of permacote" finish and light rusting. But my feeling is if you take care of it after less than desirable weather conditions,, should have no problem.
