I have been looking for a new rear sight for my S&W 66-1 ...
They are hard to find , or I am inept at searching for one ...
All help is appreciated , Thanks ...Barney:seeya:

Check Brownells or Midway. Check the rear sight width of the old sight.

A 66-1 would, assumably, have a blued rear sight and likely a white outline on the blade. My 66-1 is so equipped. I know that no dash 66 had a fully stainless rear sight and that would probably be harder than hen's teeth to find. Bear in mind that the assembly for 2.5 inch might differ slightly from the assembly for a longer barrel length.

I don't find a complete assembly at Brownell's, only rebuild kits (over $100) and a few blades. I did locate this assembly (http://www.e-gunparts.com/product.asp?chrProductSKU=300640) at Numrich for $57.50. It's listed as for a 19-5, but that should be correct to a 66-1. I also found this one (http://www.e-gunparts.com/product.asp?chrProductSKU=300520) for just a bit more which says it's for a 586-3 and is a white outline. I'd think that would work, but it would always be best to do a bit of test fitting before you try to completely install.

Last resort would probably be a call to S&W.

+1 on Midway. I didn't realize they had such a good selection of parts:

I have dealt with both Brownells and Midway... Both are good online sources...

I just replaced one on a 686 (just bought the whole assembly, it's only $5 more that just a blade) from Numrich and it's listed as a model 19 or something like that, but it's the same deal. What's important is to make sure you buy the right height - get out the calipers and measure the existing one and buy that (unless you're putting a new front on). You then go by the barrel length as well, some are different.


You want part 10-18, one of those 4 variants (well, 2 variants of 2 barrel lengths). Unlike the 686, it appears the 66 only had one height and never changed.
