Questions on Ruger 22 RF pistols

My understanding; please correct me in my errors. Standard Automatic then the first target model was called the Mark I. Then the Mark II was done as a 4 or 6" fixed sight sporter and variations were offered with target out fittings, all under the moniker of "Mark II". The 22/45 was a Mark II with the 1911 frame angle. The Mark III series made what changes to the Mark I, II, and Standard Model?
I have owned a 6" Standard Model for close to 40 years, great gun. I came into an early production Mark II 4" with box last year haven't fired it, It has been used but is very good. There are several variations of all models that I need clarification on.
Thanks for any info!!!

Ruger has managed to confuse people with their nomenclatures. Here's the skinny .... the very first 22 pistol that Ruger made was called a "Ruger Pistol" (1949-1951). The name was changed to "Ruger Standard Automatic Pistol" (1951-1954), and from 1954 to 1957, the nomenclature was "Ruger Standard Automatic Pistol 4 3/4". When the 6" barrel was introduced, Ruger dropped the "4 3/4". All fixed sight models from 1949 to 1982 were generally called a "Ruger Standard". The RST-4 had a 4 3/4" barrel and the RST-6 had a 6" barrel.

In 1950, Ruger released a model with adjustable sights called the "Mark I Target Pistol". It was identical to the Standard except it had adjustable sights and a 6 7/8" tapered barrel (T-678). Another model was added with a shorter 5 1/4" barrel (T-514) and finally a 5 1/2" bull barrel (T-512). All target models had a roll mark on the rear left receiver "Mark I Target Pistol".

In 1982, Ruger introduced the Mark II and here's where the confusion got worse. All fixed sight and adjustable sight models were called a Mark II. The target models with adjustable sights were called a "Mark II Target". The MK II was a redesigned version of the Standard/MK I. It had a 10 round magazine (9 round for Standards and MK Is) and a redesigned safety and bolt. The bolt would lock back automatically after the last round fired or it could be manually locked back. This change allows the shooter to charge the pistol with the safety catch in the SAFE mode whereas with the Standard/MK I, the safety catch was used to manually lock the slide back and could only be charged with the safety in the FIRE mode. This was a great safety feature, however most owners don't use the feature and many don't even know about it. Mark IIs were made from 1982-2005. During the last few years of production, all Target models were drilled and tapped for a scope and included a Weaver style scope base with each new pistol. The "Standard" nomenclature was dropped so fixed sight models were "Mark IIs" and target models were "Mark II Target".

More confusion .... In 1992, Ruger introduced the 22/45. There was never a Mark II 22/45 ..... even though most people call them a Mark II 22/45, their official nomenclature is just 22/45. The 22/45 had a polymer frame with the same "upper" as the Mark II. The grip angle was changed to 17 degrees to match the popular 45 cal 1911s, thus the name. 22/45s had a totally different magazine to accommodate the different grip angle. They also had a magazine release button behind the trigger, again much like a 1911.

It gets worse .... in 2004, Ruger came out with the new California compliant pistols. This was a redesign of the previous 22/45 and MK II. All 22/45s and all other models were called Mark IIIs. The 22/45 Mark III had a loaded chamber indicator, a key operated lock, and a magazine disconnect. The conventional Mark IIIs had the same modification plus they had a magazine release button behind the trigger instead of the butt release. Additionally, Ruger reinstated the "Standard MK III" with fixed sights. So now we have the "MK III Standard" with fixed sights, the "Mark III Target" with adjustable sights, the "22/45 Mark III" with fixed sights and the "22/45 Mark III Target" with adjustable sights. Both the Mk III and 22/45 are available in the "Hunter" model, which has a fluted barrel and adjustable sights.

I hope I haven't confused you even more.
