At a glance:
- Shot-peened spring offers longer life than factory spring
- Reduces failure-to-feed issues
- Replaces old, broken mag springs
Upgrade your Ruger® Mark™ Series magazines with aftermarket Ruger® magazine springs from TANDEMKROSS. Magazine springs wear and tear over time, reducing the performance of your magazines and resulting in failure-to-feed issues. Don't let an underperforming or missing spring derail a shooting sports competition or day at the range!
The Green Springs Magazine Springs for Ruger® Mark Series (3-Pack) are shot-peened for a significantly longer life than the factory spring. The upgraded magazine springs reduce failure-to-feed issues and are an ideal replacement for your old, broken magazine springs. Sold in 3-packs, "Green Springs" are an ideal upgrade to keep in your range bag for easy maintenance on the go.
The dark green color of the magazine springs is a simple way to show your #TANDEMIZED pride and keep your upgraded springs separate from factory springs.

Great replacement- install tip
If you're having trouble keeping the spring straight during install use a small diameter rod or screwdriver inside the spring. It will make it easier to slide in and insert. These are slightly longer than the OG Mark III 22/45 lite mag springs but work way better.

Green Springs MK Series Rugers
I've got a mix of older and newer 22/45 mags, some of my older mags were starting to act up a little bit and cleaning them didn't seem to help so I bought these mag replacement springs and they've seemed to solve the problems that I was having with feeding the ammo.

Magazine springs
Springs arrived in for me to install before a "steel match". Worked perfectly. Very pleased. No failures to feed.

more springs
Third set of ordered springs. Unless I use my Marv IV Lite to drive tacks, I should be set.

Green Springs
I had issues with my Ruger MK III magazines for a while. Prior to installing the springs I was at ~ 20-40 % failure rate. So after replacing the springs the pistol behaves like new. No FTF at all after 100 round. This is a great product

Ruger mk3 22/45 fail to feed fixed! MOSTLY
I had to replace my old magazine springs and I was so lucky to come across Tandemkross. It was a little more than oem but their "about us" wanting to fill the gap to make our Rugers more reliable caught my attention. I was fighting to get the first one on and it was a night and day better as it was stiff! It was way longer than the old oem magazine spring. The next one gets easier. I bought a couple new ones probably two years ago and those exhibited fail to feed. Dreadfully, I bought another set of three green springs and it fixed it. The rest was because the feedlips was needing adjustment.

Springs work well
These work well. I was looking to replace my old springs and noticed there at TKs site. So far, so good.
