The first complete guns made by Remington were the last contract for the Jenks Navy carbine, in 1847. Prior to that they were "parts suppliers", primarily barrels of both iron and steel. They probably were the first large manufacturer of steel barrels for the trade and these are very common from about 1850 on. Their first handgun was the Remington Beals revolver. The advertising tagline "America's First Gunmaker" is fallacious...Colt is older and I think S&W is as well.
