1958 to 1970

The Ruger “Bearcat” .22 single action revolver was first announced in the August 1958 issue of the National Rifle Association’s American Rifleman magazine.  Sturm, Ruger & Co. began shipping these fine little guns the same month.

The original Bearcat had a one-piece cylinder/grip frame made of an aluminum alloy that was blue anodized, a 4” steel barrel, six shot non-fluted steel cylinder that was roll marked with a “Bear and a Cougar” scene and with the words “Ruger” and “Bearcat”.  The gun had a Colt style fixed grooved rear sight and a ¼ inch tall fixed front sight with no base.  It also had a steel ejector rod housing, a concave faced ejector rod button, and a gold/brass colored anodized trigger guard.  The grip panels were rosin impregnated rosewood without a medallion.  The gun’s overall length was only 8-3/4 inches and it weighed in at a scant 17 ounces.  The suggested retail price was $49.50.

One of Bill Ruger's favorite automobiles was the Stutz Bearcat and it is said that he named this revolver after that automobile.  It is also believed that the 1858 Remington New Police percussion revolver inspired many of the styling characteristics that can be seen in the little Bearcat.  As you can see from pictures in this article, these two revolvers demonstrate an amazing similarity.

Gun enthusiasts and outdoorsmen quickly took a liking to this light, compact, quality made, dependable revolver and its introduction was a great success.  It quickly became a favorite sought after trail gun or backpack “kit” gun.

The Bearcat was so popular in fact, that due to favorable sales volumes, the August 1958 introductory price of $49.50 was reduced to $39.50 in March 1961.  It was not increased again until 1969 when the suggested retail price went to $44.00

During its production the gun had several variations, but its original design remained virtually unchanged during its 12 year production period.   Some of the most notable changes were the use of a shorter front sight (reducing the height from ¼ inch to 3/16 inch), changing the ejector rod housing from steel to anodized aluminum,  replacing the concave/dimpled ejector rod button with a flat faced button, and the use of oil filled grip panels with the trademark Ruger Eagle logo stamped into an aluminum medallion.

The Bearcat’s serial numbering is also a very interesting subject and has created much discussion over the years by collectors.  Varying opinions still exist today.

The Bearcat’s serial numbering began with number 1 and continued through 999.  These guns were first shipped beginning August 1958 and some in early 1959.     Then the so-called “Alphabet” Bearcat series was introduced.  The “Alphabets” had a 3-digit number preceded by a letter of the alphabet (i.e., A001, B458, C937…..Z999).  All of the letters of the alphabet were used in this numbering scheme except the letter “O”.  The first “Alphabets” were shipped in October 1958, during the same time that the first 999 guns were still being shipped, and continued until early 1960.  It is not known by this author exactly why the “Alphabet” numbering system was put into production.  Some believe that due to intense competition in the gun industry, Bill Ruger changed the numbering system to confuse the competition and conceal the actual number of Bearcats being made.  Maybe someday we will find out the real answer, but it sure makes for an interesting group of highly collectible and desirable Bearcats.

Discussions often center around just how many of the Alphabet guns were made by this relative small upstart of a company.  If 999 of each alphabet letter were produced this would be about 25,000 Bearcats produced in about 18 months.   One must remember that the company was also making the Standard Auto and Target model pistols, the Single-Six .22 revolver, the .357 Magnum Blackhawks, the .44 Magnum Blackhawks, and had just started production of the Super Blackhawk during this period.  Many collectors do not believe it would be possible to produce that many Bearcats in that short of a time and think that many blocks of numbers within the letters were skipped making it far less “Alphabets” made than one might think.  These “Alphabets” certainly make a very interesting and desirable variation of the “Cat” for the collector to peruse and obtain.  They will bring a premium when found in excellent condition.

In March 1960 a few special production guns were made in the serial number range 1000 to 1999.  Only a few are known to exist and are extremely rare.  Serial numbers from 2000 to 114730 were made March 1960 to December 1968.  The height of the serial number itself was changed at about serial number 35,000 from 1/16 on an inch to 1/8 inch. Then due to the “Gun Control Act of 1968”, all firearms manufactured had to have its own unique serial number…no two guns could be numbered the same number.  Thus Ruger introduced its “prefix” numbering system in January 1969.  The Ruger Bearcat had the prefix of “90” added to its serial numbers.  Known are serial numbers 90-00022 to 90-25622.

There are several very interesting and scarce/rare/very rare standard and non-standard variations of the Bearcat.  A collector can put together a fine and interesting collection if they can obtain many of these different standard and non-standard variations.

Estimates range from around 140,000 to 160,000 of these fine little revolvers being made in its 12 year lifetime from August 1958 through June 1970, when Bearcat production ceased.  They are great guns to collect and a handy “kit” gun to own and shoot.


 S/N 1 - 999

All standard features of the first guns.  Also may have fluted or  non-fluted staked front sight or a capped or drilled through  base pin latch nut.

“Alphabets” S/N A001 – approx. M500

All standard features of the first 999 guns.  I believe these all have fluted staked front sights.

“Alphabets” S/N approx. M500 – X165

The concave/dimpled ejector rod button was changed to a flat faced button.

“Alphabets” S/N approx X165 –Z999

The front sight blade was shortened from ¼ inch to 3/16 inches to lower and improve the point of aim.

S/N 2000 - 35000

Flat faced ejector rod button, shortened (3/16") front sight blade.  Steel ejector rod housings (ERH) were used on most of these 1/16" serial numbered guns.  A few blue anodized aluminum housing can be found on some Bearcats beginning in the 33000 serial number range.  

S/N 35000 – 114000

The grips were changed to oiled walnut with a light stamped Ruger Eagle trademark logo medallion and the larger 1/8 of an inch serial numbers were put into use.  A mixture of steel  and blue anodized aluminum ejector rod housings were used on the guns at the beginning of this serial number range.  At about 50000 the aluminum housings took over almost totally.  It is estimated that about 15,000 or so of this variation had the steel housings.  Most of these guns had a “SR” intertwined inside of the Ruger eagle logo in the barrel address with about 5000 of the guns toward the end of the range not having it.

S/N 107000 – 114000

The medallion in the grip panel was changed to a heavy stamped trademark Ruger Eagle logo at the end of 1968/beginning of 1969.

S/N 90-00001 – 90-25622

In 1969 the serial number had a “prefix” of  “90” added due to the “Gun Control Act Of 1968” that required every gun manufactured to have a unique stand alone serial number.


Duplicate serial numbered guns

These guns erroneously had serial numbers the same as other Bearcats.  When discovered they were stamped with a “D” prefix or suffix to the serial number.  Very few known.

Trade show samples and seconds

These guns were sold, probably at a discount to distributors and were stamped with a “S” on the bottom of the cylinder/grip frame or suffix to the serial number.  Very few known.

999XXX serial numbers

Out of sequence six digit serial numbers used in 1968.  May have been some type of duplicate numbering scheme?  Very scarce with only about 1200 believed made.

“Blackguard” Bearcat

Black anodized or “japanned” finished trigger guards, 109 believed made.  Highly sought after by collectors.

Trademark Application Guns

Two or three Bearcats were roll marked “Service-Six", "Speed-Six", and perhaps one "Security-Six”.  Used by Ruger to apply for trademark when beginning the double action “Six” Series of revolvers.  One of a kind guns.

Special Order “Gun Writer” gun

S/n 1000, a special order by Bill Ruger for writer Bob Wallack.  It has a tall front sight and a flat faced ejector rod button like the “L” to “X” series Alphabet Cats.  One of a kind gun.

Inscribed Bearcat

Inscribed on the grip frame backstrap, “To Herb Glass from Bill Ruger”.  This gun has two one of a kind features, a 3/16 inch brass front sight and a milled notch in the left side of the receiver so you could view a loaded cartridge case rim.  Only one made, s/n 16.

Engraved Bearcat

In the factory collection.  Engraved by John Warren on special order from Bill Ruger.  S/n 43813, the only Bearcat engraved by factory.


If anyone has any additional information on these little guns it would be most appreciated.  As you can see, the Bearcat has many interesting standard and non-standard variations that can keep a collector real busy for quite some time attempting to obtain good specimens.  These are great little guns….I suggest that you all get you a few!!

Another view of #16’s inscription.



View of the one of a kind factory “milled notch” of the left side of the receiver of Bearcat #16.  This was done so you can see the cartridge rim of the case in the loaded chamber.  Bill Ruger performed this alteration at the request of Herb Glass after he had tested and returned the gun.  Bill also had the Bearcat  inscribed on its grip frame backstrap and later sent it back to Herb as a gift.



View of the other alteration requested by Herb Glass after testing #16.  A shorter 3/16” fluted staked “brass” front sight blade was installed.  This is the only Bearcat with these factory alterations.
