"Bought two neither will push rounds up strongly enough to be in place to be stripped by the slide into battery. Spring may be too weak. Slide then binds on every shot."

"I purchase this magazine a few months ago. I shot at lease 500+ rounds with this magazine with no issue at all. I must be lucky to have receive a good mag, as you know pro mag are known to make bad mag. Base on my experience i might buy more pro mag magazine in the future."

"Total waste! Does not work, jams up pistol after first round. I assume junk spring but regardless it makes it completely worthless."
