You can find many to choose from that won't completely break the bank...

I have hammer guns ranging from a Thos Wild to a Husqvarna to a SIACE.

While I tend to use RST shells for everything, these are sturdy shotguns ready for many years of work. These all feature "modern" steel barrels.

My hammer guns with damascus barrels are lovely and pampered. In picking them, I basically followed the advice given above and tried to find knowledgeable dealers mostly through the Vintagers events.

Now, I have to say I LOVE my Stephen Grant sidelever hammergun the most, so there is that. Talk about a NEEDED gun.
