Mid-cap magazines fail in a predictable way. The spring tires, the follower picks up a burr or a bit of a broken BB, and the mag starts leaving the last ten or fifteen rounds sitting in the body. Nothing about the shell is worn out — the moving parts are.
This is the full set of those moving parts. One long spring, one short spring with its plastic connector, a spring guide with its screw, and a PTS Enhanced Magazine Follower. The springs are nickel-plated piano wire; the follower and connector are ABS, moulded in orange so you can see at a glance which parts in a stripped mag are the new ones.
It is a bench job rather than a field repair — you are taking the base off the mag and working inside it — but it is a short one, and it is the difference between a drawer of half-trusted magazines and a set you will actually put in a rig.
This is the EPM1 kit. PTS list a separate kit for the short EPM1-S, so check which mag you are rebuilding before you order.

Frequently asked questions
Will this fit my EPM1-S? No. PTS make a separate spring kit for the short EPM1-S. This one is the EPM1 part set.
Do I need any special tools? No. The magazine base plate comes off and the spring guide screw is the only fastener. A small cross-head driver and somewhere flat to work are enough.
How do I know it is the spring rather than the mag? Load the magazine fully, then hand-cycle rounds out of the lips. If the last handful will not lift, or the follower drags and stops, it is the spring and follower — the parts in this kit.
What is the Enhanced Magazine Follower? PTS's own follower design, supplied in orange ABS. It goes in as a like-for-like replacement for the one already in the magazine.
Is it worth rebuilding a mag rather than replacing it? That depends how many you have. A rebuild takes a few minutes and returns a mag to full capacity; a shell that is cracked or a set of feed lips that are chewed is past saving and wants a new magazine.
