Scored one of the Lipsey's run of .32 magnum Bisley's Excellent fit and finish, .314 boolit is a slip fit in the cylinder mouths, and the forcing cone is free of gouges and rings. And it shoots well; just 6" high at 25 yards, 5" high at 50 and 4 " high at 100. Rear sight is screwed down tight. For giggles I was able to hit clay birds at 100 yards by holding 1 bird low and a hair right from a sitting backrest position. Tried different loads and all shot high.My thought is that there may be a different front sight for the .32's as opposed to the .22's and I got the wrong sight.

Really don't want to send it back because it shoots good and don't want it messed with. Is a different sight available?

My 3inch first run 327fed sp101 was the same way. I bought an appropriate thickness piece of brass and filed out a new front sight blade. Got enough brass left for about 70 more, cost about 5$ and an hour's work. There might be a blade for yours , no luck on the sp101, therefore my project.

What weight boolit were you shooting?

Lighter boolit and or faster velocity will lower your impacts.

88 and 100 grain boolits. 100 grains were loaded over 4.0 of unique and 3.0 of red dot. Shot fine in another 4" .32.

I would try the Lyman 3118 or a clone thereof. I know I have older Smith Hand Ejectors and they like the heavy bullet the best. My clone mold of the 3118 comes out right at 115gr. They shoot well.

I don't need to tell you that a higher front sight or lower rear sight is the answer because you already know that.

Is there a possibility there's something interfering with the rear sight that is preventing it from bottoming out? Perhaps a burr or the spring under the sight is binding?

A taller front sight wouldn't be difficult to fabricate if all else fails.

This front sight is one piece with the base and held on with one screw.

If the rear sight is truly bottomed out (Petrol& Powder's suggestion is a good one) and you can't find a higher front sight you may be able to file down the top of the rear sight and deepen the notch accordingly. A set of jeweler's files are your friend here. I have done that on several Rugers over the years.

It sure sounds like a taller front sight blade would do the trick. You ought to go ahead and make one for your gun. But maybe someone already makes one. I don't know.

Well if you're going to re-do you sights you might as well set them up to me more useful/forgiving. If it was me I give the sights 8 clicks up and re-test @ 25yds.

25yds ='s 900 inches
right now your 6"'s high @ 25yds
Distance from front sight to rear sight blade???

Example:
I'll use 9" for the sight radius/distance from the front sight to the rear sight.

9 * (6"/900)
6/900='s .00666666
9 x ..0066666 ='s .06"

You would need to add 60/1000th's to the front sight or take off 60/1000th's off the rear sight.

I'd go up 8 clicks and re-test @ 25yds. Measure your sight radius and use the formula above to figure out how much you need to add to the front sight or subtrack from the rear sight.

Using a tight fitting screwdriver remove the front sight and fashion a .06 brass or aluminum spacer to fit under it. Screw the sight back on with a bit of lock tight and you should be shooting center. Use a magic marker to blacken the aluminum shim if it bothers you. I did that years ago to get a Single 6 22 mag sorted out. If you run a bead of clear fingernail polish around the seam after you screw the sight back on it will make the little gap less notable. What you may also try is to cut a piece of inner-tube to serve as your spacer.
Brownells may be able to provide you with a higher factory-type sight.

I really like the shim idea. One source suggested soda can for shim material.

I would call Ruger and ask if they have a taller front sight of that style. The Mark II bull-bbl target used the same style.
Larry Gibson's solution is easy and works well also.

I see someone finally mentioned that you should call Ruger.

Simply put,,, a lower rear blade,,,, and or the addition of a taller front sight will be quickly supplied by the cost will be free quite often if you ask nicely. it won't change the gun in any way,,, and is an EASY fix.

Make the call.

While more expensive, Williams offers their Fire Sight set for the Bisley. My tired old eyes would approve of this option.

I have the same problem with a Ruger Bisley but with fixed sights, I called Ruger they sent me a new front sight, when it arrived, it was the same height, I ended up keeping the new sight to install if I ever sell the gun, the old sight I built up with Liquid Steel,filed everything square then using my pet load kept filing the Liquid steel down until I reached the POI I wanted. Also used a black marker to make everything look the same.

Tack a nice piece of brass to the front sight with JB weld and file to your desired point of impact then shoot alot until you're happy with the DOPE. Now you can get or make a replacement sight or solder a piece on to make the same height and file it to nice contour. I did that with my New Vaquero and was never sorry.

I just use JB Weld to build up the front sight, file it down the next day at the range to get it where I want it using a finger nail file & paint it black with a magic marker. It's easy to take off if you need to. Done it one a lot of my Rugers.

Ive filed a small flat on the top of the front sight and soldered on a piece of brass several times. Careful filing and shooting will dial it right in.
Ive also used a piece of brass brazing rod on a couple guns. My old Webley has a V notch rear sight and a brazing rod front. Best sight picture of any gun I own. If you hold it on a grouse head and squeeze easy you won't have to eat supper from a can.

Did the know weld on a B84, only lasted a couple years. I wondered about soft soldering a brass pad, y'all have ovaries me to get on with it.

Ruger sent me a new front sight that is identical to tbe one on the gun. I have some epoxy putty I could use and JB weld but the JB weld is pretty runny. Now I nave a project.

With the JB Weld I use some release agent on some light plastic or wood & then clamp them with a small clamp. Then add the JB Weld & it works quite well, just use more than you need & file off the extra to square at the range.

Took the revolver and the spare sight to the gunsmith. I suggested that maybe a steel ruger sight base with a pin in blade might be able to be screwed on if drilled like the single six base. Gunsmith said he could probably make something. Kinda annoyed that it came to this but it show much potential and didn't want to send it back since it was dimensioned properly and finished up good.

How about just adding a small weld to the top and filing it back down to the desired height and re-bluing?

Or threading for a small Allen head screw and then filing the screw down to the desired height?

Or cutting the blade off the base, drilling and counter sinking the base from the bottom to hold a taller blade ?

Or cutting the blade off, milling a length-wise dovetailed slot to accept any number of taller blades ?

With a spare base, the possibilities are only limited by your imagination.
