I have a pietta Griswold & Gunnison .44. It shoots about a foot and a half high at 25 yards. Any way to adjust the sight so i dont have to aim so low?
 
Have you thought about a temporary front sight? Just make it a little taller than the one on the revolver. The temp sight can be just about anything. You can probably hot glue something to last you long enough for a few shots. Even a bit of duct tape would do. If it gets you close to where you want to be, make a new sight. Leave it tall so you can adjust it with a file. :hmm:
 
Like bushhippie said.
Deepen the hammer notch.
I have G&G also but in 36 cal.
It shot a bit high and the deeper notch worked.
I also opened the rear notch for a better sight picture.
 
(1) Change loads: more powder ususally gets a higher point-of-impact, so try to reduce the charge.

(2) I'd be very reluctant to change the hammer by removing metal. You would need to reduce the height of the flat above the hammer, not just the notch. You could really butcher the looks!

(3) Raise the front sight. You can calculate the amount with the ratio of the front sight height to the sight radius to the amount high at the distance.

Or try some duct/masking tape to the front sight to get an idea of the amount you need to raise it.

I'd try at least 1/4" more and see what happens.

(4) I don't know how Pietta holds the fron sight. You can fabricate another higher sight from brass sheet stock. You will probably need to remove the existing front sight, maybe its a screw-in, or swaged-in. Once out, you could try to reproduce it in brass (easy to work) but a higher profile

However you remove the front sight, it is an irreversible action, so be prepared.
 
Thanks for the suggestions guys. I looked at the sight, it may be threaded. so im hoping. If not, I have these welding sticks that when you heat them they turn to liquid so if i could pour into some kind of sleeve or mold. Maybe lol. As far as the charge, its a foot and a half high with 15gr fff. I dont really want to go down anymore.
 
You might want to try using a heavy powder load instead of a light one. It might lower the point of impact.

If I'm wrong I'm sure someone will correct me but pistols are weird things when it comes to velocity and the point of impact.

One would think that a heavy powder load and high velocity would raise the point where the ball/bullet hits but it isn't necessary so when it comes to a pistol.

With a high or a low powder load, all pistols recoil quite a bit.
A lot of this recoiling happens long after the ball/bullet has left the barrel.

If the powder load is small, the ball/bullet is moving slower so it stays in the barrel longer and the recoil of the gun ends up pointing higher by the time the ballet/bullet gets to the end of the barrel.
This makes the gun hit high.

If the powder load is large, the higher velocity of the ball/bullet will get it out of the barrel faster while the gun is just starting to rotate because of the recoil.
This makes the gun hit low.

I'm not saying more powder will solve the problem with the gun hitting too high but it will have an effect in the right direction.

Speaking of all of these old Civil War type pistols hitting high, almost all of them do it.

I've heard they were supposed to be sighted in for 50 or 75 yards, depending on who I'm listening to.
Whichever it is, there was supposedly a directive given to all soldiers who carried a revolver in the CW.
"Aim at the belt buckle" was the advice.

The way most of these pistols shoot, if a person aimed at the belt buckle at 25 yards he'd probably hit the man in the chest.
 
The Pietta front sight will be pressed tightly in a hole. You can grab it with pliers and pluck it out. I have seen old ones that the sight is threaded and will unscrew. That hole can be drilled and tapped for a No.6-48 screw and then the head can be file off for a taller front sight.

Here's a video fixing the problem you have. This guy is sighting in at 15 yards instead of the 25 you talked about, so I'm thinking it should be about the same distance to modify your hammer.

Hope this helps.
 
I tried a little rigging, pulled the sight out. cleand the hole. took a brass finishing nair and filed the head untill i could wiggle it into the hole. took it out and heated the barrel very little. still touchable. then headed my welding stick and dripped it into the hole. quickly put the nail in and wiped the excess. Let it sit for a while and all set. Now I just have to cut and grind
