Z8 mag for g43 - Shield Arms Z8PM8NC Z8 Magazine 8rd Flush Fits Glock 43 Black

Really like the idea of this product, have had this 43 for a long time and never had issues with it. Usually would carry with the factory 6 round mag as a quick pocket carry gun. Have a few mags with various different mag extensions and never had issues on the range. Bought this z8 mag thinking it was going to be a game changer considering I have a 43x with the z15 mag and has performed flawlessly. Had continuous issues with either double feeding or failures to eject with the z8 mag. Ran about 50 rounds through it with the z8 mag and had at least 1 malfunction per fully loaded magazine typically within the first 3 rounds. Not sure if it has too strong of a spring or another issue, it is also very hard to get the last round in the magazine using anything but plain old fmj range ammo. Maybe leaving loaded for a long time will help with this issue but as far as using it as my new carry mag which is really what I was intending to use it for is off the table.
