    I just went through this with one of my firearms. I was getting malfunctions with three (3) separate magazines (Its a Sig, with factory Sig magazines so by no means a cheap bran). I changed the springs out and have had no problems since. Upon comparing the springs there was a huge difference. I can send you a picture if interested. The mags were approximately 15 years old. Just food for thought…..Thanks for posting vids!
