Ruger Mark I rear sight?

[upnorthwis]

Is the Ruger Mark I read sight drift adjustable? Hits 2-1/2" left at seven yards. Doing this for a friend and don't want to try to move something that's not supposed to move. She's got the original box and instructions with it too.

[Shawlerbrook]

Yes they are. I replaced mine with a fully adjustable sight.

Thank you. I saw that sight as an option and I'll mention it to her. Although at this time she would be adjusting it to account for a massive flinch. Yes, even with a .22. I'm working on curing it.

The early Rugers,, with the fixed sights were called "Standard" models. The rear was a drift adjustable one,, but no adjustment for elevation. The "Standard" model went into the MK II & MK III series. It became the main way to discuss the fixed sighted guns.

So, to clarify things a bit,, there are MK I's that have factory adjustable sights.

There were also aftermarket sight kits to put adjustable sights on a Standard Model. (I know,, as I have a set in the package here.)

The original MK 1s had heavy tapered barrel 6”+ and micro rear sight. There were several after markets, Millet being most popular because it was cheapest.

This one must be the Standard Model. Serial # 10-61XXX. Nice original box too.

Leave the gun alone. Correct the flinch.

Rear sight can be drifted. But dont bother. Different ammo, different bullet impact.

Adjustable sights will require a new front sight.

Leave the gun as is, for collectors value.

The picture shows a nice later production Standard Model. (Model RST-4)
As for collector value, there is not a huge interest,, as those guns were made in fair quantity. But a complete package,, like shown (well, it doesn't show the brown shipper, or the wax paper,) is very nice. I noticed the one slotted magazine,, so it has the A-54 frame. And as for the year of production, it was made in 1970 according to the serial number.
You can drift the rear sight,, and it can be drifted back into position when the shooter learns to not flinch.
But as noted,, it's best to work on the flinch first.

50 year old gun. Was my first MK1.

[upnorthwis]

It shoots left with me shooting it too. (and I'm really good). Tried to move sight yesterday with a one pound hammer on a brass punch and it would not budge. Was thinking about making a fixture for putting it in a vise.

[contender1]

That old of a gun MAY have dried grease,, or even a little rust under the sight. A padded vise is a must for tapping on sights. And remember,, a LITTLE movement goes a LONG way.

[upnorthwis]

I am done with this sight. Brass drift pin is leaving indentation marks in the steel sight. Her brother says he will look at it. It's all his. Last thing I need is to damage someone else's gun by hitting it with a bigger hammer. There is not a spec of rust on it either.

a drop or 2 of Kroil

[upnorthwis]

Gun is not in my hands anymore, and not a moment too soon. Can't even imagine a dovetail sight taking that much of a pounding and not moving. I'll have her tell her brother to try Kroil.

A little off-topic, but that's a nice gun.

As stated, Ruger made a lot of them and the collector's value isn't huge but that's a fairly nice one.

Most of those Standard Pistols were used hard and used often. So finding one with a nice finish and with the box is a bit better than average.

While not a super rare gun by any means, still a bit special.
