Purchased two in the Hastings bankruptcy auction and I prefer to keep the one with the cantilever mount.

For sale:

NIB, Hastings Paradox 24" slug barrel for Beretta 390s and 3901. Shoots 2-3/4 and 3" 12 gage slugs, gloss finish, rifle (open) sites, 1:34 twist, never fired.

Price is $300 to your door, no FFL required.
