The Cowboy is carrying dual Colt Walkers, which are both six shot black powder revolvers. During the shootout in the bar he clearly fires way more then 12 shots, and there is no way anyone could reload a cartridge revolver quick enough to fire that amount of shots in that short a time frame, let alone be able to reload a muzzle loading black powder revolver that quickly.
When The Saint of Killers returns to Cooley's Saloon for vengeance and after the Massacre the shots of the bottles against the bar back shows modern labels listing ingredients as well as a UPC Bar which obviously would not appear on any liquor bottle from the 19th century.
The Sheriff reads out the list of arrests, as well as media coverage of Cassidy's arrests, which span over 70-80 years, all of them in the USA.
