The Colt 1836 patent expired in 1857, and the next year, Remington introduced a solid-frame design that was both elegant and reliable. The 1858 Remington became so famous that it was the prevailing choice of military officers following the Civil War. The full-frame design of the Taylor's & Company Pietta 1858 Remington New Model Navy Black Powder still makes it a top choice for black powder shooters today as the cylinder can be removed without taking the firearm completely apart, unlike the Colt models.
