Little Guns, now Employee-Owned
Formed originally in Salt Lake City around 1971 as the Rocky Mountain Arms Corp, the company that today is North American Arms was founded by Richard J. Casull, who was also the father of the .454 Casull cartridge.
A gunsmith gifted with both exceptional intellectual ability and creative productivity, Casull was the holder of more than 20 patents including several filed in the 70s for small, single-action revolvers with a floating firing pin and an improved cylinder lock system.
These things:

I’ve owned a ton of little 22 Mini Revolvers over the years, and they are nice to have in your pocket while hunting or fishing.
Rocky Mountain eventually changed its name to North American Arms around 1975 while Casull later went on to found Freedom Arms in Wyoming, with NAA concentrating their efforts on mini-revolvers while the newer FA went on to produce more full-sized guns.
For most of its modern existence, or at least the past 30 years of it, NAA has been owned by a top-shelf gentleman by the name of Sandy Chisholm.
Well, Sandy, looking to spend more of his time in Florida than Utah, has eschewed offers to sell out his mini-revolver biz to other players in the firearms industry– a move that would have likely seen it shift production to a Big Factory somewhere to save costs, leaving most of its current rank-and-file behind to look for another job– and instead has transferred ownership to a trust to make it employee-owned.
Class act.
Nice pocket mouse gun. They have wide array of styles in both 22LR and 22WMR. And both Hornady & Speer have rounds for home defense pistols.
