It is a R-R frame and the right side looks OK, though the markings might be a little light. But the frame color is not quite the same as the slide. The little inspectors mark below the magazine release on the left side is also missing, and the lengthwise striations could indicate that the frame was belt sanded and re-parked, which would explain the missing FJA. The grips look to be the wrong color, but that could be a trick of the light.
