When to replace the recoil spring and magazines on a pistol

A pistol is a machine, and parts of a machine wear out. The first to go are the springs: the recoil spring (which returns the slide forward) and the magazine springs. A tired spring doesn't look broken, but it causes feeding and ejection failures at exactly the wrong moment.

What wears, and how fast

The table is a rule of thumb only. Numbers vary by manufacturer and model, and the manufacturer's instructions come first.

Part	What happens when it wears	Typical replacement interval
Recoil spring	Slide doesn't return fully, feeding failures, sharp recoil	A few thousand rounds, per manufacturer
Magazine spring	Round doesn't rise, failures on the last round	When failures appear, or every few years under heavy use
Trigger spring and trigger parts	Soft or slow trigger	Have an armorer inspect
Barrel and sights	Larger groups	Rare on a personal pistol

If you carry daily and shoot little, wear is slow, but springs still tire with time. A magazine that sits fully loaded for months isn't necessarily "ruined", but it's worth rotating your magazines now and then.

Signs it's time

• A casing that doesn't eject or jams in the ejection port;
• A round that doesn't chamber fully;
• The slide doesn't lock back after the last round;
• One "problem" magazine while the others work. It's almost always the magazine;
• Dents or rust on the magazine body.

What to do in practice

1. Check the manufacturer's instructions for the recoil spring interval.
2. Mark your magazines (number or color) and note which one had trouble.
3. Replace a problem magazine, don't force-fix it.
4. Recoil spring: replace per the manufacturer. You can do it yourself if it only needs field stripping, otherwise use an armorer.
5. After replacing, test by shooting at a licensed range before trusting the pistol for carry. Fire at least a hundred rounds with no malfunctions.

As always, anything beyond field stripping is left to an armorer. And before any work on the firearm, unload it and verify it's empty.

Track it instead of guessing

The common problem: nobody remembers how many rounds went through the gun since the spring was changed. In Kadurim every firearm has a total round counter that updates with every session you log, and a maintenance list. Add an item, for example "recoil spring, every 3,000 rounds" or "optic battery, every 12 months", and set the interval in rounds, months or both (whichever comes first). When it's due, or close to it, the item shows on your home screen. After you replace it, tap "Done" and the count starts over.

The starting numbers are suggestions only: change them to match your manufacturer's instructions. Cleaning stays separate, with its own interval: how often to clean a pistol. And for the counter to be accurate, log every session. The same idea works for optic and weapon-light batteries.
