I sent my Gold Combat Stainless in for some cosmetic gripes. The good folks at the custom shop took super-good care of me. They replaced the slide stop, among other parts. The new one is a bit different looking than any other I've seen. The back side of the flat part has a relief machined all the way around the perimeter. The checkered "thumb paddle" part has a protruding shelf that really catches on the thumb for easy disengagement of the slide stop apparatus. The part directly under that is concave (dished-out) rather than convex. It is pretty spiffy looking and has really peaked my interest. Anyone else ever seen one like this? Brand? Thoughts?
