Rem 870 magazine replacement springs

[Ram Rod]

Want to ask where to get some of the best replacement magazine springs for extended tubes?
I'm going to get some for my 870 Police Magnum with 6 shot tube. During my search I've seen the 6-7 shot springs so guessing they are the same length or just cut some off for 6 shot?
I do want quality springs, not just cheap replacements. I've seen the Wolff extra powers for $8.99ea or 5-PK for $35.99
Should I even go for 20% extra power springs if I'm going to change every year?

[BKinzey]

Wolff would be an excellent selection.

I wouldn't change the springs every year. Springs wear out due to use, expanding and contracting. A fully compressed spring doesn't wear out because it is compressed. So unless you are shooting a lot, like competitively, I'd just do function checks. Most people won't wear out shotgun springs in a decade, probably more.

Yeah, I didn't know anyone other than Wolf made springs for guns.

The price of Wolff products is quite commensurate with the quality. I think you don't need to consider other alternatives.

Do you have any recommendations for affordable alternatives by any chance? Not a fan of salvage or used parts...
