I own the .40 caliber version and it is a fine accurate weapon. The only downsides are parts and mags. They are expensive and hard to find. Had a small part issue and a buddy of mine who works on guns made it for me and installed it.
I think I paid $260 for mine years ago. I do think some S&W auto mags work in the 9mm version.
