100% a mag issue. Fix or replace the mag and ensure the bullet tip is angled up towards the feed ramp and it should feed the cartridge without issue. I generally tweak mags a little to ensure this is happening.
You can see the one Sid feed lip has been bent up a tiny bit, you can always "tune" metal mags with the correct tools. The one feed lip needs to be slightly bent down so it contacts better. There are a few videos out there on how to do this.
