Problem with 930SPX extended mag tube

[Cletus1]

Hi everybody. I'm new to this forum and to tactical shotguns. I recently bought a used 930 SPX and was pleased to find out that it performed great with zero malfunctions...until I installed a Nordic tube/barrel clamp.At that point,I could load 5 rounds in the magazine,but it would bind up when I tried to load the sixth. Take the clamp off and it works fine.I noticed that as I was unscrewing the mag, it had a slight wobble.So, it seems that when the clamp pulls the magazine to a slightly different angle, it causes the follower to bind.Should I try a Nordic +2 mag?

Silence is golden.

Sooo...a guy walks into a bar and asks" Hey bartender, whats the difference between ignorance and apathy?" The bartender says " Man, I don't know and I don't care." Get it?

Nordic mag tubes are thin walled ali, tighten the clamp too much and it will constrict it.
Also make sure it stays in line with the barrel when you tighten it.

Does it work if you swap parts back to the OEM configuration???
