4. North American Arms
When it comes to pocket pistols, they don’t get any smaller than North American Arms. While NAA produces semi-auto pistols in .25, .32 and .380 calibers, they specialize in rimfire mini revolvers.
In 2018, NAA produced over 49,000 such revolvers in various .22 calibers, including their then-new break-top Ranger II in .22 Long Rifle and .22 Mag — the second-most rimfire revolvers made, only to Heritage Mfg.
Fun fact: In the 1980s, wildcatter Dick Casull (of .454 Casull fame) owned Rocky Mountain Arms, which later became North American Arms. After several years, Dick and his then partner, Wayne Baker, “sold” NAA to Frank Talley of Talley Manufacturing and moved to Freedom, Wyo. to reengineer NAA’s line of mini-revolvers and large frame single-action revolvers. NAA’s version was chambered in 45 Long Colt/450 Magnum Express, while the new Freedom Arms’ models were chambered in the eponymous 454 Casull.
After both companies manufactured both product lines for several years, NAA discontinued manufacturing of the large revolver and Freedom discontinued producing the mini-revolvers. Today, NAA is known for its mini-revolvers while Freedom Arms, which ranks 11th (435 total revolvers) on this list, is known for their big-bores.
(Thanks to NAA President Sandy Chisholm for the history lesson!)
