Like the Open Top Army model, Cimarron's 1872 Open Top Navy has been accurately reproduced in every detail from an original arm in our antique collection, right down to the 1851 Navy-sized grips, just like the early-production 19th century Open Tops. Further, this quality replica is chambered for the .38 Colt/Special cartridges for those who prefer a lighter caliber sixgun. The Open Top Navy model is a spitting image of the originals and is ideal for those who prefer the '51 Navy's grip size.
