View Full Version : Ruger Mk I

04-26-2010, 2:53 PM
I was at the local gunship perusing their firearms and I saw a ruger mk I on consignment for 250 w/3 mags looked to be in good condition. Just wondering if that was a good price and if there's any issuesi should be looking for with the mk I. Also they had a 22/45 for sale for 295 Im wondering if that's a better deal.

Which version is it? Bull barrel or standard - Either way it's a decent deal - I personally do not like the 22/45 due to the grip -

It looked like a standard 4.5" barrel. The bull barrel is thicker and more rounded I believe(feel free to correct me if Im wrong) and this one was thinner and tapered to the end.

Also I was wondering if one was easier to take down or clean than the other? I recall someone saying that one of the models was a PITA to clean and reassemble.

The Ruger MK I / II / III take down procedure is the same EXCEPT the Mark III has the magazine disconnect. The take down procedure requires at two points to do a dry fire. The magazine has to be in. And then it has to be out at other points. I call it the Ruger Hokey Pokey dance. So for a Mark I, it will be slightly easier than the Mark III.

When I purchased additional magazines for my MK I (Ruger mags), they did not have a metal base pad. The plastic base pad of the magazine had a gap which would get caught in the magazine release latch. I had to modify the magazines because of that. MK 1 is a 9 round magazine.

The 22/45 has a different grip angle and you may be able to get more aftermarket parts for it, if that is of interest.

I'll guess that the MK 1 has fixed sights, I don't know my 22/45 history well enough to say if that one has fixed or adjustable sights. Take that into account as well.

I've got a Mark I and two Mark III's. Nice guns.

Here's one offered by a Calgunner in LA. http://www.calguns.net/calgunforum/showthread.php?t=286209
If it is as clean as it appears, I would snap it up for $300 although I would prefer a MKII because I'm a shooter, not a collector.

I have an old one that shoots great. Keep in mind that the grips are also different than the II and III and are hard to find.

So how old is the mk I? I'm just looking for something affordable and shootable.

If you have the serial#, go on the Ruger website and you can see the year it was made.

I'm a believer that the Mk II is the best version.

That said, any iteration of this pistol is a fine shooter.

I ramped my front sight, installed a flourescent green insert, Clark Custom trigger and a BoMar rear sight.

Friggin thing's a laser.
