I have a Union Switch and Signal 1911A1 Slide. It's a replacement slide used but retains about 90% original finish. I was going to use it for a build but I want Novak Sights and a lowered ejection port. I can buy a Caspian already setup for this, and it'd be cheaper than paying a smith to alter this slide. I was going to post it for sale (prob on the (ehem, cough) CMP Forums), but I have no idea to ask. Any help would be appreciated.

Thanks
Justin
