625-3 Sights

[RetDet]

I obtained a 625-3 with a BEN serial nr,
4" bbl, 45acp.

The sights had been changed to XS, and the tritium is dim from age. I prefer the standard sights and will be restoring the original condition. At least more or less, as I will be using a ramp front whether or not those were standard.

S&W reports the standard front is 0.243" H and the rear blade is 0.106H.
The figures are at odds with those I have seen here in the past, which are front=0.30". I have not seen rear blade dimensions.

Does anyone have an as-issued 4" he would measure for me, or please direct me to accurate corroboration to the S&W dimensions?

Many thanks.

Oh, and WELCOME!

Was the front sight base modified for the XS sight?

While not the original sight heights probably the most common "upgrade" is to a .160 rear / .300 front. The .160 rear has a deeper notch and gives a better sight picture, be the front black or FO.

tennexplorer, I don't believe the ft sight base was modified for the XS. It appears that a heavy dose of sealant and the pin hold it in the factory slot.
tomcatt51, thanks. I will seek those sights. I used to have a revolver with a particularly deep notch, probably 30% deeper than my others, and as-issued from the factory, and I loved that sight picture.
