well it's more metallic feeling, the retro feels smoother in a way. not to say it isn't smooth, it just feels different. also I was using it with a return spring which took a little getting used to (it's a fairly stiff return spring), but I liked it a lot. Not as quiet as the Retro, and not as light, but a straight shooter. My greatest concern with it was how uncomfortable the grip was compared to the Retro, especially the second finger against trigger guard (even with gloves), but keep in mind these parts are manually machined, even the radius down the back of the frame is clearly hand-cut with file!
