Adjusting sights vertically
 
My brother has a .22 revolver that he recently got and the sights are adjustable left and right but not vertically. I was thinking of putting a shim under the rear sight since it shoots so high. Is this a bad idea? What should I use as a shim?
Thanks

Shimming the rear sight will make it shoot higher. Bet it is the sight picture, user error. The top of the front sight needs to be level w/ the top of the rear sight. This link has a pic.

Well all 3 of us had the same problem so... I have shot iron sites on other guns without difficulty so I think I know how the sight picture should look.

Best of luck then. Go ahead and shim the rear sight while you are at it also. You sure fouled that up. That is why I said user error. You don't know. You may think you are correct, but sadly you are not.

jpattersonnh is correct raising the rear sight will raise bullet impact. Could file down the rear sight.

Sorry for being short. I really was attemping to help. Many mistakes are made w/ those not accustomed to certain firearms. What kind of .22 revolver?

Would have to very carefully reshape the rear sight notch if a goodly amount of adjustment is needed, but yes, that would work.

It is a tanfoglio single action. Not many out there but it still goes bang so it is fun. Any suggestions for what to use as a shim? I thought a couple pieces of paper so I could gradually bring it up but I don't know how that would hold up.

Really, raising the rear sight will make it shoot higher. Bullet strike follows rear sight adjustment, meaning rear sight up, bullet goes up, left/left, right/right, down/down.

If the gun is shooting high, you want to lower the rear sight, or somehow raise the front sight, as bullet strike goes opposite of front sight adjustment. The only way I can think of to adjust the front for elevation is to weld metal to the top of the sight, and then shape it with a file.

I'd just adjust my hold. It's not like you're after long range accuracy.
