Ruger Mk I vs. Mk II

Saint

If I have a Ruger .22 pistol, how can I tell if it's a Mk-I or Mk-II, and is there a really big difference?

Second question:

WHat is the proper way to clean a Ruger Mk-II pistol, and a S&W .357 magnum, and do they need "complete" strip downs adn cleanings after every firing session.

MKI does not have a bolt release on the left.

If you strip it to clean it your going to need this and some luck (Practice)

Mk 1 doesn't have a bolt release at all. Also, the Mk 1 has the loading button on the rt side and doesn't have the machined cuts on the receiver rear where you grasp the bolt (slide).
I take mine apart every ten years or so. It's a pain to reassemble.

don' t listen to these guys [:D]all you got to do is get the hammer strut in the right spot and things goright together couple minutes tops , really it does only take a few minutes IF you do it a few times and get the hang of it ..
no bolt hold open lever on the Mark I , pull bolt all the way back and push safty up to hold the bolt open

I'm getting conflicting info here.

This weapon to stay locked open you needed to pull back on the bolt/slide, and push the safety (on the LEFT side) down. Pushing it back up released the slide.

The safety is both a slide lock/safety and slide release.

So what do you think? Mk-II or Mk-I?

Can I find out for sure with the serial number?

When did they stop making mk-I and start making Mk=II?

You don't need the serial number. On the rear of the reciever there are small cutouts on the Mark II to make it easier to grasp the rear of the slide to pull it back. These are very obvious & easy to see.
When they came out with the Mark II they also claimed they had made improvements to the trigger. If the price is nearly the same the Mark II is a no-brainer.

1982 was the change over year from MkI to MkII
The MKII is very obvious with the left side hold open with a slight cutaway on the top in the left grip this is absent on the MKI
The last MKI ser# 17-70981
The first MKII 18-00001
Post your Ser# and I will tell you when it was made

on the Mark II , on the left side , behind the grip is the safty , forward of that is the slide release lever , which is a smaller metal tab that sticks out from the top front part of the grip , there is a small cut out in the grip that allows the lever to move down when you release the the slide ,
also on the Mark II if you have a empty mag in the gun , and pull the slide all the way to the rear it should lock open , also when you are shooting it, when you run out of ammo it should lock open . the Mark I DOES NOT DO THIS


On the Mark I on the left side there is ONLY the safty , if the slide is closed and the safty is in the safe position the bolt/slide will be lock , with the safty in the fire position the bolt/slide is free to move rearward ,, IF you want to lock the bolt in the Open position you need to first pull it all the way back and then move the safty into the safe position

Simply said,the MK 2 bolt stays open after the last round is fired.The MK 1 does not.

As mentioned above, the Mk II has 2 conveniences lacking on the Mk I; the bolt hold-open and the receiver taper to more easily grasp the bolt. Note that later Mk I's have mag button on same side as Mk II, and I believe, use the same grips as Mk II. The EARLIEST of the Mk I,s have an advantage over the Mk II. They have MICRO sights rather than Ruger sights, and a lovely trigger action that the Mk II does not have. In the early days I believe that they worked them over at the factory. Either pistol is a wonderful value.
