Single Stack Magazine Spring Replacement Interval?

[BangSwitch]

How often should you replace the magazine springs in a 9mm single stack gun?

I checked my maintenance logs and I have north of 5k rounds in one set of magazines that's 3 years old.

Another batch of mags is newer, but shares similar round count.

 

Since they only run about $8ea, it's pretty cheap insurance.   (until I did the math on a dozen mags!)

 

I'm a big fan of the Dawson Precision 9mm 10 round magazines.  I've been using them for a couple of years now and find them to be very reliable.

Give Dave Dawson a call and see what his take is.

I called.
The answer was "the magazines will tell you.  When you have issues feeding the last round or second to last round - it's time to replace"
In general, they believe the 9mm magazine springs are good for 10-15k rounds

I agree 

BUT

Springs are cheap so buy new springs for the most used set and use the other set for practice and watch for the above signs then change those.

Changing the main set is more insurance so you don't get "told" by the mags during a match!

Yes I speak from experience!!!
