Did S&W offer more than one height of rear sight blade? If so, how would I determine which one is in my gun.
My 63 shoots high, even with the rear sight as low as it can go. No way to put in a taller front sight.
Thanks.

You can measure the height of your existing blade using a micrometer or caliper.

S&W offered three different blades for the model 63 rear sight, a .101" and .128" for the 4" barrel, and a .086" height for the 2" barrel.

If you decide to change the blade, you'll also need a new windage screw and nut, and possibly a new plunger and spring for the J-frame sight assembly. (the J series screw and nut are smaller than the ones for the larger rear sight assemblies that fit the K, L, and N series revolvers)

rear sight

When you take the rear sight apart do it inside a big zip lock bag, I've lost several detents over the years. Once they fly it's almost impossible to find them.

Much depends on how you hold the revolver. My 63 shoots about 5" high at 25 yards with CCI SV ammo if I shoot bullseye style with one hand. If I hold it extra firmly, the point of impact will come down. Also, HV ammo will bring the point of impact down some and using a two-handed hold will bring it down more, maybe even to point of aim. Just some things to consider before changing a rear sight blade.

This will all vary a bit from shooter to shooter, but generally I've found the above to be true for virtually all revolvers.

Thank you for the responses.
I will give her another outing before I do anything. The last time, was the first time that I shot this gun.
Part of the issue might be that my old eyes don't pick up the red ramp as well as they should.

J-frame guns, regardless of the chambering are not easy to shoot well unless you're an experienced handgun shooter. If you're in that less-than-skilled category like most of us, give yourself sufficient practice time before making an assessment on changing out anything. Good luck-

I agree. As much as I like the size of j frames, and the looks of 63s in particular, and have owned a 63 and 317 in the past, they don't so well in my big paws. I will however, give it more range time.
Hoping to snag a 617 that I know about. If so, the 63 might be going away.
I'm no longer in collector mode. One .22 revolver will do.
