"The Quigley® rifle itself was a custom conversion from a cavalry model breech loader and it retained the patch box and saddle ring from that incarnation. The older 1863 rifles shot non-metallic paper cartridges, loaded from the breech. The falling block served to slice off the end of the paper cartridge and expose the gun powder. The Quigley® 1874 conversion was rebarreled and re-worked to fire 45 calibre 110 grain metallic cartridges. The 45 -110 stands for 45 calibre and 110 grains of black powder ... Authenticity is everywhere in this movie, including the time it takes for a heavy 45 calibre bullet to travel 1,000 yards AND the fact that it gets there a noticeable few moments before the sound of the shot can be heard by the bad guy who's getting shot!
The Quigley® Rifle used in the actual movie was made by Shiloh Rifle company (Powder River Rifle Company). Its rumoured the movie production schedule had to wait in line three years for the rifle to be completed! After the movie it was donated by Tom Selleck to the NRA for a fund raising auction. In 2010, Powder River Rifle Company acquired the Quigley® trademark from Cimarron Firearms Company. See the actual rifle at ShilohSharps Rifles."
"The Movie Is Magnificent - Tom Selleck makes the Quigley® character into a hero we all wish we could be. He wins the love of a beautiful girl, beats the bad guys with heroic American style, and introduces the audience to the deadly efficiency of Single Shot Rifles... See the Movie. Own the Gun!"
