My thoughts are....
....that I have owned three of the 1963 Remingtons and IMO the most disappointing thing about the revolver is the trigger design.
But my thought is that it would be tough to develop a fully enclosed trigger guard for such a small revolver that would accomodate the pointing finger of most shooters.
I can see why Remington settled upon the design they did.
