Would like better sights on my 60-15. Mostly the shallow rear is what I'm finding hard to replace.
Most sights I like are made for K frames. I believe the k frames have a larger sight which is just what I want. Don't think the complete rear assembly from k frame will fit on j frame. But I'm wondering if just the blade part would fit?

These seem to fit the screw set for all j frames. Don't know for sure.
Smith & Wesson Rear Sight Assembly .086 Black J-Frame
My 60-15 has sights which work with all I shoot in it, .38 HBWC, .38 Berry's 125gr and 158gr JHP, and rarely .357 158gr JHP.

Not sure if the blades for a K-frame would fit, but they would be too tall and mess up your point of aim. You need a blade that's .086" tall, and I seem to recall the lowest K blade is about .106".Your best bet is to look for an aftermarket sight, maybe a fiber optic.

If you replace the rear with a larger/taller sight you likely need to add a taller front sight which I could not imagine you would not wish to do anyhow. There is a sight height calculator at Dawson Precision to give you a good idea.

Sight Calculator

I replaced the fronts for fiber optic on a 617 and 60 but cannot seem to find them on Dawsons website any longer.

When you say "Larger sight" which isn't very specific, and from what else you say we can only presume what you mean.

You won't find an off the shelf product that I know of, to do what you want/need. So I'm sorry of that's what you're looking for. However, none of the suggestions below are rocket science:

1. If it's a larger rear sight NOTCH in the sight blade, file it or have it filed deeper and wider. 10 minute job.

2. if you need a front sight blade which is already a full 1/8" wide, replaced with a wider blade, it's simple since you're gun is stainless you have a blue steel blade pinned into a mortise in the sight base. (common owner or gunsmith work), 10 minute job.
Or here's a do it yourself glue on front sight for single actions. Just use it backwards on your S&W front sight with a little filing to fit: Sure Hit Sights

3. If the rear sight blade is not high and/or wide enough, replace it with a K/L/N size sight blade fit (filed) to the smaller J frame rear sight base. Including filing the blade's sight notch wider and deeper. 30 minute job.

If you don't have the filing skill for #1 or #3, there's any number of gunsmiths who do. And skills for #2 as well.

Hope this helps,

How much is point of aim difference on that assortment of rounds?

That's the problem. No one makes aftermarket rear sights for j frame. I know there taller and would require taller front sight

Thank you. Meprolight is one of the ones I really liked.. filing won't work well on dot sights or fiber optic, guess I should have mentioned those.
The meprolight sights only replace the blades front and rear. I know the base size is different so sights that replace the base also will not interchange. What I'm wondering is if just the k frame blades can be installed front and rear? If for example they fit on the bases with front and rear both being 1/4" taller than factory j sights I would think k frame sight blades could be used on J frame. Of course rear sights that require rear base replaced would not working without machine work being done

As I posted, the K frame rear sight blade can be fitted to the J frame rear sight base.

All you need to do is file the K frame rear sight tang a little narrower on each side to fit the J frame sight slot. No machining needed.

See/read Post #5 here: V or U Rear Sight for Adjustable J-Frame

So whether you use the K frame blade or the entire K frame rear sight, some fitting by filing is required.

The front blade on your Mod 60 is the thickest made by S&W, 1/8". K, L or N frame front sights are not any wider.

I think I understand what your saying now. Thought you was talking about filing the depth of notch to match front sight. Have you ever tried swapping k and j frame sights?

If you mean front sight, yes:

This is a 1966 Mod 30-1. My homemade non-factory target model, made into a .32 'Kit Gun', 4" J frame target model.

.22/32 Kit Gun adj rear sight, J frame Type 2, and K frame 1/8"
ramped front sight w/sight base. The original front sight on this fixed sight gun was only 1/10" wide.




If you mean rear sight, no:

I've only put a post war S&W J frame micro click rear sight on a pre war target I frame that was missing the pre war sight. Same process as installing a K frame sight on a J frame; the tang needs shaving .015" per side to fit the J frame milled slot in the top strap.

Depending on which K target sight you use, you may need to drill and tap a new hole in the top strap slot to line up with the front tang retaining screw. And just a reminder, although the rear blade will be larger, the notch is the same size as in the J frame rear sight blade.

Well, they do, but maybe not what you want - they're for the purpose of turning your gun into a fixed-sight model (D&L Sights.)
HiViz used to make an adjustable fiber-optic sight, but I'm not sure if they're discontinued. There may still be some on Ebay or other similar sites.
The blades made for K and larger frame sights are too big for the rear sight frame on the J. As was already said, your best bet might be enlarging the notch on yours - but that will almost certainly change the point of aim so much that the sight will no longer be useful.
Unfortunately, other than a complete "ground-up" customization - which is not beyond being done, of course, provided you have enough money for it - your best bet might be to just leave it alone.

NO, no, no....enlarging the sight blade notch will not affect the point of aim one iota. The notch can be made as deep and wide as you want.

As long as the top edge of the sight blade is not monkeyed with and the notch is widened evenly on each side, point of aim does not change.

So if you swap in a K frame rear sight blade which is larger, the pt of impact will go higher before even touching the notch; and has nothing to do with enlarging the notch. If one does fit and install a K frame sight blade, that's what the elevation adjustment is for. If there's not enough adjustment, lower the top edge of the blade with a file.

Enlarging the notch on the original sight blade will change nothing except for an improved, easier to see sight picture which is the stated need.

OK.... but I'm gonna have to think about that for a while.
I'll pull out my 60-10 and compare to a K sight too. I'm pretty confident that the blades are not interchangeable.
If I'm wrong, I'm wrong, no excuses. I'm also stubborn, so further study will be done.

You ARE RIGHT, of course they DO NOT interchange! I think you may be speed reading because I've said that in my posts where I mentioned the K frame sight blade swap, including my last post you quoted:


"Fit" DOES NOT mean install, "fit and install" means to be fitted, to file, to make fit, modify etc., so it CAN THEN be installed.

No worries, it happens to all of us!

Well sir, you are probably right, so I'll give you the tip of the hat.
Speed reading and thinking out loud don't mix...guilty as charged. Thank you!
