Welcome to the forum! Take it to a gunsmith. What you should have done to start with. If you need to work on a gun, and have no experience doing that work, it's always better to let those that really know how, do the job.

 

Ouch, that sucks.!!:banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead::banghead:

 

File it down to a smooth flat base, make a new sight from steel, silver solder it on.

 

I would take it to a good gunsmith. That sight (as I am sure you know) is part of the barrel. I would see what they have to say. Thats not a cheap gun.

 

Take it to a reputable gunsmith and if he isn't busy,
should have you out of there in 45mins.
Depends on whether he has the right height.
You can do it yourself, but I don't know what
Ruger uses to secure them now....solder or epoxy, or.....

JLA can surely tell you what they use.
You can also alter the front sight at this time if you wanna spend
the money. Have a Blackhawk sight put on [drill, tap, screw] but
I don't know if you can get the height or what it would look like
with the trough rear. Or have both sights changed to target.

 

That might not be a bad thought.

Find out where the sight, as it is now, hits "on". 50 yards, 100 yards, whatever. If that's a distance you might conceivably shoot, cool. Flatten the top of the sight, so you have a good smooth surface. Have a piece of blue steel silver-soldered to the top of the stainless sight. Then cut the blue piece to the right height that you wanted - for 20 feet or 25 yards, or whatever.

Now you use the blue portion for your closer, "every-day" shooting, but when you want to reach out, you raise it to the blue/silver junction. That's the spot for "long range" shooting.

Elmer Keith had horizontal notches cut in the face of his front sight, and gold wire in the notches. If he wanted to shoot at 25 yards, he used the top of the sight. Shoot at 50 yards? Use the top gold wire as the "top of the sight". Shoot at 100 yards? Use the bottom gold wire.

The picture is too big to post it, so I'll just link it.

The thing is, he did not have to guess how much sight to hold up. The gold bars gave him a mark. The silver/blue junction would give you a mark.

 

Elmer....what a man.....

 

I have a Vaquero with a lowered front sight. It was put on by a gunsmith and he did a good job. If you can find someone that does cowboy action shooting they should know of a gunsmith in your area that knows exactly how to set it up. They can also angle the sight for reduced glare which is a plus.
