replacement mag spring for mossberg 590?

[savasyn]

I'm considering picking up a replacement mag tube spring for my mossberg 590. The factory one still works, but it seems to barely kick out the last shell from time to time(weaker than when new). This is one of my HD guns so I want it to be 100% reliable.

Are there any aftermarket springs worth looking at or should I just get another factory one?

Thanks!

I recommend a Wolff spring. http://www.gunsprings.com/index.cfm?...&cID=2&mID=103

Wolff, clean and polish the inside of your mag tube.

I used Wolff with good results. pretty inexpensive also.
