Can anyone recommend a good source for replacement springs for 17-rnd 9mm M&P mags?
I don't see them listed on the ISMI site, or the Wolff site (although curiously, Wolff does list .40 mag springs... ) Any other recommendations?

Thanks,

I think Kenny just has the "extra power" springs for extended base pads though, right?

they are fine for regular hicaps too.

Thanks Mike. Would you recommend the extra power ISMI springs over the stock S&W springs?

Now that I think about it, wouldn't it be the same spring for a 9mm and a .40 mag? Seems to me that whenever I see 9mm mag springs listed, they're described as "9mm/.40"

I'm not Mike, but I work with 3 guys named Mike, if that counts Here's my thoughts...

I run the extra power springs in all of my M&P .40 magazines, including those with the Taylor basepads, and the stock 15 rounders. They are of heavier wire, and I feel they assist with sure feeding. Especially important if you leave ammo in the magazines for any amount of time such as a carry gun or nightstand piece. I chucked my factory ones after 6 months, as they didn't have a lot of oomph left in them. The extra power ones are holding up beautifully after 7 months. Good stuff indeed.

It does count; Chris!
I agree, I would get use out of the stockers instead of just throwing them away; Im too frugal and the stock springs do work fine.
but yes, when time comes for new springs, the +10% is good with or w/o extensions.

I'm not Mike either but yes same spring for 9s and 40s for the M&P. The only reason not to use the +10% springs is you may not get 10 rounds in your "Jersey mags". If you are using standard capacity mags then no reason not to use them.

Not trying to rob Kenny of business, but did you check Brownells, I got some factory replacement springs there one time

Thanks Mike, and all you helpful "not Mikes" too...

I'm just now getting around to replacing my worn mag springs with the ISMIs that I picked up... I noticed that they don't have the bend at the top that the factory springs have to fit into the follower; did you bend yours yourself to fit? Is it imprortant to get the bend angle and length perfect like the factory spring, or will it work OK as long as it's bent good enough to fit in there?

Ok, so everyone has heard the addage of "if it ain't broke, don't fix it". I'm wondering what to think of my mag springs. How many rounds do you shoot through a mag before you swap the springs out? Do you just do it annually? I've got a variety of mags with a variety of rounds through them and I just can't decide what to do with the springs.

On another note I broke a base pad a few weeks back. S&W is supposedly sending me replacements (they're on back order now). How frequqently do you guys change out the base pads?

I bought a bunch of base pads to have as spares, their cheap. I've only had to replace 1, I check them after each shoot since I do a tear down and clean if they had hit the ground......

I can see significant difference between my 2 year old mag springs and the new ones.

If you're waiting on a basepad, I've got some extra. PM me your address.

Any one place where I can get the stronger springs and compact baseplates? Save on shipping.
