Pawnee Bill didn't break all of those little glass balls with bullets.
Instead, exhibition shooters riding in wild west shows fired small
shot cartridges in Colt revolvers fitted with choked, smooth-bore
barrels. Such guns would be classified as sawed-off shotguns today
and taxed accordingly.
This SAA model utilizes the English ball and shot rifling
system devised by Colonel Vincent Fosbery and popularized by Holland
&Holland under their Paradox trade name. The barrel has
a rifled choke that shoots bullets exceedingly well but still produces
useful shot patterns perfect for aerial trick shooting. It is also
BATF legal.
Like any proper gun, this US Patent Firearms revolver features a
browned Damascus barrel. The receiver is color case hardened and the
balance of the metal carbona blued.
