Amen! Jack's is a second home to many an old Spanish gun owner...IF you find yourself in need of a part, look to this outfit:

If a listed part is out of stock, don't worry they'll make more soon enough, and the quality of the parts that they manufacture is top notch.
If a manufacturer and model or specific part are not listed, call them.
They often have what you're looking for, just haven't gotten it cataloged online yet.
well, old guns of all types
