Recently got a 1949 vintage 63. I have wanted one for years as a companion to a 1907. It is very accurate, but shows the age of the design every time there's a feeding bobble. My substitute for a "forward assist" is the tip of a screwdriver against the rear edge of the extractor. Also, mine refuses to feed hollowpoints. The tips are just flat enough that they catch the bottom of the chamber every time.
I bought a new recoil spring that I use with high speed ammo, and CCI Blazer functions and shoots very well. I shortened the original for use with standard velocity ammo, and it is quite accurate with those.
Like other things I could name, it's very likeable in spite of a few annoying habits.
