When I went in Top Dollar today there was an interesting 1911 on the shelf. It has an older Colt slide on an Essex frame. It did look like the ejection port had been lowered. It looked like they had used a stone to try and remove the markings from the left side of the slide. A "Kensight" adjustable sight has been stuck in the rear dovetail and a new front sight installed. The most interesting part was the front of the grip frame. The dots you see project from the frame like little spikes. I don't know how they made these. It gives a good grip though. Also has an aluminum trigger with overtravel screw. Maybe SumGy can offer some insight into it. The trigger pull was nice and I've never seen any grips like it has. It's marked $499. If it stays there long I might have to make an offer on it.
