All the Sharps are falling blocks. Mine is the Pedersoli Quigley in 45-70, have added the Soule vernier on the rear and a globe front. Pedersoli makes a fine rifle and their barrels are second to none. A good American made Sharps is at www.shilohsharps.com real fine rifles but more than I can go. While you are there you've got to check out the trophy room, some real fine buffalo. There are other makers, but these two come to mind right off.
