Hi-Standard Question

[JCHannum]

Over the weekend, I picked up a Hi-Standard Sport King 22 auto. It is fixed sight. On the rear of the slide behind the sight is what appears to be a screw. I initially thought it was for windage adjustment, but on closer inspection, it is doubtful it is for that purpose. The question is just what does it do and how?

Jim,
I don't recall any screw there, does it look factory?
Could be the dovetail was worn and the screw used to fix the sight?????

[JCHannum]

Ken;
It is factory, I had another Hi-Standard with the same screw, and never could figure it out on that one either, but had no reason to fool with it. I want to add an adjustable sight to this one but don't want to destroy something in the process. It is serrated on the edge to add to the mystery.

Here's a photo;

I have no idea Jim, had never seen that.
Hope some one knows, I am curious as well.

Does it click when turned, appears to be some serrations there?

Maybe a trigger sear adjustment ????

Part of the problem is the wide slot does not accomodate a standard screwdriver and I cannot get it to turn without doing some damage to the slot. The slide is only about 1/4" thick in that area and the "screw" does not protrude on the other side.

I can usually dope these things out, but this one has me stymied. The gun is in nice shape and I do not want to goober up the screw slot.

Mine is much older HD model with adjustable sights. As you can see from the pic of the slide below.



The sight is held in place by this binding screw above the firing pin.



That binding screw is, in turn, locked by this screw on the underside of the slide.



If you remove the screw from the bottom of the slide it releases the firing pin. To adjust the sight you just loosen the srew on the bottom of the slide, then loosen the one above the firing pin.

Maybe the screw on your frame captures the firing pin mechanism? Of course I'm just guessing.

I looked at several of the manuals here:

Hi Standard Manuals

But none of the exploded drawings seem to show that screw. Maybe the owner of the site can help?

Jim,
Success, at least in part, no clue what a "wear Plug" is.

I believe that the plug you describe is not a screw or even a threaded part. It simply fills the seat for the adjustable rear sight and it was only relevant on the Sport Kings when the adjustable sight kit was installed. Thus the serrations. Note the position of the elevation screw in the above diagram for the adjustable rear sight, relative to the dovetail in the slide.

Maybe "wear plug" means it prevents wear of the serrations while the fixed sight is in place?

Thanks guys, wear plug it is and its function with the adjustable sight makes perfect sense now.

I have always admired the Hi-Standard pistols and lusted for their target models in the 50's. I had another one that I parted with a while back and ran across this one at a price I could not turn down. I am planning on a heavier barrel and adjustable sights for it, one more project on the list.

I picked up a Mauser 98 action at the same time and same very low price range, so the list grows.
