I have done a search and come up with 1,965 responses, but none of them answer the question: What are the (major) differences between the three Marks? Can you help?

TIA

Tom
 
The first generation, of which the Mark I was the target version, had no "hold open" feature after the last round was fired. The safety also funtioned to lock the bolt, in either the open or closed position.

The Mark II, in all its versions, separated the bolt lock and the safety, and added the "hold open" feature.

The Mark III moved the mag release to the same position as found on a 1911... an improvement. Unfortunately, it also added a loaded chamber indicator and a magazine disconnect.... bad things, according to this old fart.

All three generations were available with either a 4" or 6" light tapered barrel with a rear sight adjustable for windage only. Then, there were numerous bull barrel, heavy tapered target barrel, fluted heave barrel, slab-side barrel, and who-knows-what options. These variations included a rear sight adjustable for both windage and elevation. Later Mark II and all Mark III pistols were drilled & tapped for a scope base that takes Weaver-type rings.

I seem to remember that the MK I also only held 9 rounds in the magazine.

Thank you very much for this, I was wondering about the difference between Marks I II III and 22/45's. Just the Zytel frame.

wwb -Thank you much! I think I will be looking for a MarkII.

Best,
Tom

Allthough you really want the Mk 11 ,if you happen onto a good deal on a Mk1

you would be wise to snag it up. I say this because other than the last shot

bolt lock ,they are the same and like the 129.00 SKS /W/box cleaning gear Ect.

Pretty soon the masses will catch on to the(TRICK)and you won't find any of

those Darned old bargan MK 1 or 11's anymore.

Well said, Bob. I have noticed the prices creeping up on the MKI's, and some of the MKII's are already getting to be pricey. Still, there are tons of bargains out there, and if one looks regularly, should find enough bargains to do some horse trading for the ones that hold price on the tab bit high side. My eyes are scanning around for one of the 6 7/8" MKI heavy taper target models. I've seen those from under 2 Hunskies all the way to 5 Hunnert!

I wonder if Ruger has ever thought of trying to get the .22WRF chambered in a Mark III? Maybe make it a double stacker and a couple of different barrel lengths..... Hmmmm...... Dear Santa......

..and the Mark I comes without the owners manual printed on the barrel...

Sorry but the last MK-Is had this warning, some time in 1978 to 1982. Serial number range, of course Plus or minus. 14-85000 to 17-8XXXX.
 
As luck would have it, I found a very nice Standard at the local gun show over the weekend and bought it. There are a few rust spots under the grips on the stamped frame, and a lot of old lubricant in the action being protected by layers of dirt, grime, powder residue, and, I assume, some metal dust.

I cleaned it thoroughly and am pleased with the results. Serial #888xx

My MarkI target holds 9 in the mag.

BTW, it has been a great range weapon. Fires pretty much everything I put through it. Very accurate. Never done anything to it besides clean. Great trigger action.

NOBODY...NOBODY, has gotten the differences between STANDARD, [Change]I, [Change[ 2, and [Change] 3.

The suspense is killing us. Please enlighten the uninformed. :o

The Mark III ... it also added a loaded chamber indicator

Although I find this feature unnecessary (who doesn't rack the slide to see if the gun is loaded... oh I forgot the Hollywood types) is there anything negative mechanically that this "feature" causes?

There have been some folks who experienced extract/eject problems with a Mark III.... removing the LCI cured the problem. Most folks, however, have had no problems with them.
