Default 1903 front sight installation question

I installed a new front sight base on my 1903, but now the spline notch and pin hole on the base do not match. It appears that the notch on the spline needs to be drilled out to match the pin opening. Is this standard procedure when installing a new base? or am I missing something. All parts are USGI, want to make sure i am going about this correctly, any help would be great.

It's not unheard of.

A little work with a tiny round file on the spline ought to fix you up.

Another option is to try a bunch of other front sight bases to see if you can find one that lines up better.

The pin hole was drilled after the front sight base was pressed on the barrel. Therefore, no two pin holes are exactly alike. Your dilemma is common. A re-drill or a little filing as described by M1Garandy should solve your problem.

Hope this helps.
