I had a little trouble installing my extention on my Nova.

The spring appears really long- but only because it hasn't been compressed and taken a set. When I compared the stock spring with the factory extended mag spring I noticed that the stock spring's spirals were noticeable closer. When I first assembled it, I could only load 4 rounds. I left the rounds in the tube and carefully unscrewed the tube, then barrel retaining nut. As I unscrewed, I heard the spring jump in the extention. After that, I tightened it back down and could load 7 2 3/4" shells.

I think that the spring might be pinched when you first install it, due to the uncompressed length. I suspect that a coil of the spring gets caught in the threads between the end of the mag tube and the barrel retaining nut. Upon examination, I notice a small ledge in the middle of the nut.

Hope this helps.
