Weapon Trivia Wednesday: Innovation in Iver Johnson’s Safety Automatic
Mike the Mook
When we think of revolvers and innovation we most often think of wheel guns made by Smith & Wesson, Colt or Ruger. Yet one company stood out from these, and made innovations that had longer-lasting implications in handgun development: a company started by a Norwegian bicycle engineer named Iver Johnson.
Most often considered an also-ran or suicide special by today’s handgun aficionados, the Safety Automatic closely resembles top-breaks made by Smith & Wesson during the late 19th century with one notable exception: it made use of a transfer bar safety. A transfer bar is a small piece of metal that rests between the hammer and cylinder in order to prevent the revolver from discharging when dropped. The revolver will only fire when the trigger is fully pulled to the rear. Bill Ruger famously incorporated the transfer bar in his 1973 versions of the Ruger Blackhawk and Single Six and later in the company’s Vaquero series of revolvers.
Designed by fellow Scandinavian immigrant Andrew Fyberg and patented in 1896 under #566,393, this ‘Hammer the Hammer’ action was critical to making revolvers safer. Before this innovation, a shooter risked an accidental discharge if the revolver was carried with hammer down on a loaded chamber. When you had only five or six rounds in your Roscoe, not having to give up one to keep from shooting yourself in the junk was a serious improvement.
IJ’s innovation did not end with the transfer bar; they produced a “Hammerless” version with an internal hammer for ease of draw, capable of being fired from the pocket if need be. The hammer was internal, rendering it a true “double-action only” revolver. Later versions went a step further and incorporated an additional safety in the form of a button on the trigger that would only allow the revolver to be fired if this smaller button was depressed while squeezing the trigger. This is very similar to the trigger mechanism on Glock pistols.
This meant that the springs would last longer and were less prone to breakage or taking a set.
Iver Johnson revolvers were offered in both a small frame version with a three to six inch barrel in .22LR (7-shot) or .32 S&W (5-shot), and a large frame .38 S&W version that came in barrel lengths as short as two inches.
When introduced Safety Automatics retailed for $4 to $6, which in today’s currency is about $125 to $150. It was one of these, serial number 463344, that anarchist Leon Czolgosz shot President William McKinley with in 1901.
The company produced a variety of other revolvers later in the twentieth century as well as shotguns, M1 Carbines, a .50 BMG sniper rifle, etc., with no real innovations like their initial efforts. However, notoriety still followed them as an Iver Johnson Cadet was used by an assassin to kill presidential candidate Robert Kennedy in 1968. Today, these old top breaks can run anywhere from $20 for complete but nonfunctional revolvers, to pristine shooters for $175. Production ceased in 1941, making them all C&R eligible with the bulk of the Second Models and the entire First Series classified as pre-1898 antiques.
Their most distinctive feature (when vetting other old top-breaks) is the distinctive “owl head” logo found on the grips. The owl was a Scandinavian symbol of wisdom and reflects the thought process that went into the design of these “cheap pocket pistols.” So much wisdom went into Iver Johnson pistols that their features were all later incorporated into not only other revolvers but also most striker-fired semiautos, nearly 100 years after Iver first produced them.

About the Author: Mike “the Mook” Searson is a veteran writer who began his career in firearms at the Camp Pendleton School for Destructive Boys at age 17. He has worked in the firearms industry his entire life, writing about guns and knives for numerous publications and consulting with the film industry on weapons while at the same time working as gunsmith and ballistician. Though seemingly a surly curmudgeon shy a few chromosomes at first meeting, Searson is actually far less of a dick and at least a little smarter than most of the Mad Duo’s minions. He is rightfully considered to be not just good company, but actually fit for polite company as well (though he has never forgotten his roots as a rifleman trained to kill people and break things, and if you look closely you’ll see his knuckles are still quite scabbed over from dragging the ground).
