I have one for my 627. It's pretty tight on retention but I'll heat it up and adjust it. My thought was that with so many N Frames out there, it must have been mine being larger than average. Overall, I'm happy with the product. It's loud but I'm not hunting with the 627 as a primary. The noise hasn't scared off any grouse I've shot with it and it's comfortable to carry or ride a quad with all day.
