Ruger 22/45 - I need some info.
I just bought a used Ruger 22/45 Target Model.
It's in good condition, but other than the serial # on it - I have no idea if it's a Mark II or III.
Or when was it made?
Any advise on how to find this out.
I want to buy a couple of mag's for it
Do the 22/45 mags fit both Mark II & Mark III 22/45"s or are they different?
Thank you for your help.
use the SN to find the year of MFG

MKIII will have a loaded chamber indicator and magazine disconnect. The polymer lowers will look different from the II to the III as well.
The MK-III will have the loaded chamber indicator bar visible on the left side of the receiver tube (large green oval), and should be stamped MK-III (smaller green oval):
The MK-II will not have any slot or bar visible on the left side of the receiver tube, and will be stamped similarly to the photo below (my own MK-II 22/45):
Ruger shows a different part number for the MK-II 22/45 and MK-III 22/45 magazines, so I assume there is some kind of difference between the two models. I don't know if the mags for one would function in the other, as I have only bought/used MK-II mags for my MK-II pistol. Links to each, at Ruger's online store:
"Placement is power" -- seen in an article by Stephen A. Camp
(RIP, Mr. Camp; you will be remembered, and missed)
That is very helpful.
By the way if you are interested - here's a good source on Ruger .22 information

The magazines are, unfortunately, different.
Mk II mags won't work in a Mk III.
I haven't tried the Mk III mags in a Mk II yet.
