“I took some pics but they suck. The gun doesn't look anywhere near what it should. Me taking the pic blocks out the light from above and there's a shadow.”

I fought light for a while when taking pictures of my Smiths. I now wait for a full sun day, then find a shady spot and take my pictures in the shade. Eliminates the shadows and provides a good even light on the gun surface.
May give that a try.
Congrats on a nice buy
