I think they’re out of business. The website homepage is dated 2010, but I didn’t see any way to contact them. I think now the only way into an underhammer rifle is custom or DIY from a kit, unless you find a used one from H&A or another maker.
I bought a .36 Cook underhammer pistol from Pedersoli, direct from the Italian Firearms Group. Took about four months to arrive from Italy. Have yet to shoot it, but it’s on the list.
