Can't get Cattlemen revolvers to shine online in PC

[Vendetta]

I'm having problems with the customization of the Cattlemen revolvers on PC. After customizing my Lemat revolvers with silver and gold with full engravings which came out nice and shinny, I added pearl grips to one of my Cattleman revolvers and made all exterior medals silver, however the gun just will not shine.

It has this matte appearance similar to the look of silver weapons when viewed on the table at the gun shops. I really don't have any idea of what I can do here to make this revolver shinny. Never encountered this before where guns will not look shinny after adding silver to them. My Cattleman revolvers on Xbox are all silver with full engravings and gold inlays and they shine. These revolvers on my PC do not have full engravings but I wouldn't think that would effect anything.

For reference, the revolver on the left side in first person is factory stock medal while the revolver on the right side is all silver. Anyone ever encountered this before?, any tips to really make silver guns shine?. Only thing left to do that I can think of is contact Rockstar support.
