I just got this baby in the mail a few days ago. It is to replace my Diana 5G Magnum , which I sold. The built quality is what one would expect for a Diana product. I tested it out in the garage , and will go to the range in a few days. Tom Gaylord has got speeds over 700 FPS. I will probably put a scope on it , but I wanted to shoot it with open sights first. It does have 11MM grooves for scope attachment.Do not hesitate to get one if you want a fast , hard hitting pistol..
