Well, about a month ago I decided to upgrade one of my Glock 19's. I bought the +2 extenders for my mags. I haven't shot them since but, wondered if the 15 round mags would have an issue with the 15 round springs, with the 17 round set up now? So I purchased a set of Wolff springs for 3 mags. They are called the extra strength springs for the Glock 17 mags. Look good, but I don't want to have issues. Any thoughts?
