New to Me Ruger Standard 22lr

[Labguy47]

I believe that's not a MK2- its a "standard", also known as a Mk1. Pretty sure what is on the left side is the safety/slide lock, with a heel mag release. If that is the case, mags from later models won't interchange.

Actually as long as they have the rounded mushroom style of the standard, MK I or MK II he’s good. It wasn’t until the 3&4 that they put a flat circle on. Same time they added a bolt release lever like a slide lock.

That's what I love about this site. If its a specific item being discussed, SOMEONE here is a subject matter expert on it. I actually learn a lot here.

It's not clear what post you are responding to. The "Standard" was the original tapered-barrel model, whereas the Mark I was a bull-barreled target model. So they are not the same.

Current magazines have a "bump" on the right side of the body, to engage the 1911-style mag release on the Marks III and IV. Nevertheless, they still work in the earlier guns with the heel mag release. (Perhaps the bump might make for a tight fit in some guns -- I tried them with mine and there was no problem.) In fact, the current magazines have provision for moving the follower button to the opposite side, so they can be used with the very earliest guns.

Collecting Ruger .22 magazines is a hobby in itself. The variations are fascinating. Nevertheless, Ruger always had an eye for backwards compatibility.

ETA: I don't think the flat versus rounded magazine follower button is a problem either.

I thought the "standard" was the tapered version, "target" was the loger tapered one, and the bull barrel was called the bull barrel on the earlier guns. I was under the impression that all of these guns became known as MK1 by default after the MK2 was developed. Mine is a short taper-barrel gun with heel release and safety/slide lock in one.

I bought my first Ruger pistol in 1972. Here's what it says on the end of the box:

RUGER MARK 1
.22 L. RIFLE -- BULL BARREL
TARGET PISTOL
Catalog No. T-512 5½" Bbl.
STURM, RUGER & CO., INC.
SOUTHPORT, CONN. U.S.A.
​

This is verbatim from the box, which I have kept all these years. (This was before the Mark 2 was developed.)

At the time, "Mark 1" was the designation for the upgraded target model. The plain ones were known as the standard model.

Really I quoted the post just like I did for yours. And you are correct in stating that the upper receivers are not the same. A lot of MK Is had bull barrels or elongated target barrels. A lot of MK IIs have what I would consider bull barrels or full circumference barrels that are practically the same width as the upper receiver. This trend continued into the 3s when the hunter came out with a bull barrel that had reliefs cut out to better balance the weight and added rosewood grips and an adjustable rear sight.

A Nambu pistol has NOTHING in common with the Ruger Standard/Mark design - it is completely different and has the trigger linkage running down the outside of the frame - the gun can be fired without even touching the trigger (like a Beretta). The Ruger does not have a slide - it uses a a cylindrical bolt in a tubular receiver.

This might be a little help in the take apart, reassemble department.

Here is my Mark I it dates to 1962 and has the optional wood target grips.

I always shied away from the standards since I was of the mind that adjustable sights were a must. Have had an MK1 Target, couple of MKII's and an MKIII. Few months ago, held my dad's MKIII Standard- out of all of them, they seem to be the most "handy" feeling. I am also a fan of the heel magazine release.

As far as spare parts, I'd say maybe an extractor or two and some recoil spring assemblies. They used to be cheap, but the only ones I can find now are the ones by Volquartsen- which allow you to replace just the springs and not the whole thing. I don't have any experience with those, but hopefully someone who does can chime in with how they are.

I always referred to the original fixed sighted tapered barrel guns as standard models. I had MKI made in 1982 with the 6&7/8" barrel and adjustable sights. But I am confused most of the times by the names they are given so don't quote me. Now I just have two of the old style guns with 4&6" barrels and fixed sights and the old style mags.

Ruger sells mags that will work in these guns but you have to swap the button from the right to the left side. Some in the feedback page said the button would drag in the slot in thw mag well. I had that happen once. I just took out the button and chucked it in a drill and spun it while dressing down the height with a file. Problem solved.
