The more I look into getting a blue finished 1911, the more I'm wanting something with the older enhanced slide. The one with the flat top, angled cocking serrations, and none on the front of the slide. Is the Gold Cup the only model produced like this now? I saw a photo somewhere of one with this slide on a Govt. model. What years was this produced? As also with the officers model. I just like the looks better than the straight cocking serrations.
