Question: Anyone know what S&W says about putting slugs through the Governor? The booklet is silent. Can't see why it'd be a problem, but wondering. And if yes, which type, plain or sabot or does it matter?[/QUOTE

Check out .410 slug performance on Box of Truth.

The Box O' Truth #53 - The Taurus Judge, Revisited - Page 1

He used a 3" Taurus Judge, but the results should be the same with a Governor.
