Good afternoon all! I wanted to share a little troubleshooting tidbit I came across recently.
I have a beautiful German P220 that I've owned for 15+ years now, and it's likely twice that old (purchased used). I have some of the magazines that originally came with it, along with a bunch of Sig OEM and ACT magazines that I've purchased after the fact. I can't count how many rounds I have through this weapon. As one of my favorite pistols, round count would have to be in the thousands (probably around 3-4k if I had to guess).
During my last range session, I had a few failures to feed, where it seemed like the slide was outrunning the action and failing to grab/chamber a new round. Checked what I could at the range, re-lubed her and ran it the rest of the day and only had one more hiccup.
When I got home, I thought I'd do a real deep clean of the gun and magazines. When I took apart the mags, I noticed that the springs on the OEM Sig mags (likely the oldest ones) were noticeably shorter in their "relaxed" state vs the ACT springs and the other newer Sig mags.
Ordered some new springs for the old ones, left the newer ones as-is.
Average relaxed length of the "tired" springs: 6.25"
Average relaxed length of the other springs: 7.5"
Average relaxed length of the NEW springs: 8.25"
Made it out to the range this weekend with the new springs. 100% functionality, ran 4 full magazines full through each of the units that has a new spring.
I know deep down we all know that magazine springs ARE a wear item, but definitely one that I rarely (if ever) think about. I'm just glad that my FTF was an easy fix and wanted to share, hopefully save the next guy some heartache!
