I have 4 shields, 2 Shield 9mm (Safety No safety) 1 Shield 40 and 1 Shield 45. I have not had one single issues with any of the magazines. The 9mm no safety i shoot and carry the most has been 100% flawless with factory 7 and 8 round mags. I also use the Magguts +2 springs which have been equally flawless. recently attended a Steel frenzy course (700 + round count) used my Shield 9mm for most of that course with NO issues. S&W may had a bad batch of Shield springs, But for the most part they work and work well
