what is the difference between ruger mkI, mkII, and mkIII .22lr pistols?

Question

do they come apart the same way, etc?

Answer 1

The MKI & MKII come apart the same.

The MKIII's have a magazine disconnect and you have to leave the magazine in it to dry fire it for disassymbly. But you have to take the magazine out in order to have clearance for the take down lever to pivot.

It's more work to take apart the MKIII's. But the owners manual with show you how to break it down for cleaning.

MKI's did not have an external bolt catch. You had to hold the bolt to the rear and put the safety on to lock the bolt open.

MKII's have a bolt stop lever above the grip on the left side. so you can push down on it to release the bolt or up on it to lock the bolt open when you hold it to the rear.

MKIII's have the external bolt locks just like the MKII's.

The MKI & MKII have magazine release levers on the bottom of the grip. you cam it back to release the mag. The MKIII's have a button on the left side behind the trigger area.

The MKI & MKII did not have magazine disconnects. (you can't fire the gun if the magazine is not in it.)

Hope this answers your question for you.

Answer 2

Basically the same with minor improvements to the Mark IIs like cutouts to improve access to the cocking ears on the bolt, a slide lock/release button, and last shot bolt hold open. The Mark III has an improved magazine release button.
They are superb, well made, real accurate, and nearly indestructible pistols. I don't believe you can buy a better .22 pistol. It's called the 'Standard' as in the standard by which all others will be compared. In other words, if your .22 pistol isn't a Ruger Mark I, II, or III, it's not as good.

Answer 3

The Ruger Standard (the predecessor to the MK I), MK I, MK II, and MK III are all on the same basic design.
To my knowledge the only major changes in function was late in the production of the MK II when Ruger added a Bolt back on empty feature.
Where as when the magazine is empty the bolt is blocked back, and must be released once reloaded.
I have the first 3 models Standard, MK I and early MK II and none of mine have that feature.
But as to the tear down and reassembly these 3 models and including the MK II 22-45 deal with the same basic component parts groups.
When I teardown, clean and reassemble any one of my 3 I do so in the same manner.
Schematic attached of two variations so as for comparisons ONLY.
But in my opinion your answer is yes, the are all basically the same.
Hope this was of some help.

D58

Answer 4

The MK III (which I would not buy-even at a discount) has a frame mounted magazine eject button (like a centerfire pistol) and an ugly loaded chamber indicator that sticks out like a sore thumb. D58 was forgot to mention that the MK II aslo has a 10 round magazine in contrst to the 9 round magazine that the Std. and MK I had.

Answer 5

i've got owned the standard vehicle and the MkII with the bull barrel yet have basically seen the MkIII My basically criticism relating to the MKII is that it somewhat is rather very barrel heavy, I want the previous usual vehicle's pencil barrel for weight distribution does not something in any respect except you inspect it the project of the loaded chamber indicator inflicting unintended discharge replaced into fastened awhile back, it somewhat is extremely bumped off if it bothers you I hate locks yet like the actuality that the magazine launch is extra American friendly The previous heel launch is a Euro layout The magazine disconnect provides some variations that makes disassembly/reassembly extra stable I bumped off the MD from my hi capacity and it made the gun lots extra advantageous, according to danger an analogous could nicely be finished with the MKII

Answer 6

Ruger Mk1

Answer 7

To add to D58!
I read in shooting times that they also changed the link on the cross pin to aid in disassembly. I own a Mk II and to my knowledge the differences between the three is MkI,II,III is changes (they call them improvements) to the previous design. Like S&W does with there auto pistol IE 459, 5906, 6906.

Answer 8

I'd trust D58. He give good answers.
