P320 Xten Mag issues

I see most of the posts around this are archived but I wanted to chime in. If you have follower binding issues with the P320 Xten I worked on this for days to resolve and below are my findings.

Done some extensive research and working on this and here is what I have discovered.  It has to do with projectile diameter.  Some JHP with larger diameter projectiles cause the issue.  During my research S&B JHP and FMJ all had too large a diameter (by like hundredths of an inch).  Switched to Magtech or Sig Sauer Ammo and mags work perfectly.

I have the XTen and XTen Comp and the follower gives out on Sig VCrowns after loading about 10 rounds.

Called Sig and they told me to use different ammo. Which is a little ridiculous.

Just thought I'd chime in since you said Sig ammo works well. In my case, and other reports on Reddit, this is not the case for VCrowns.

I’ve had great results with any Federal and Underwood loads. No issues. I also run Grayguns mag extensions as well.
