My question is because FN store states that the 509 CC magazines are compatible with other 509C models.i don't have one yet but my guess is going to be no since the LS Edge take a different mag than the 509 series does.they are also almost twice the price of a standard mag as well.
i don't know the exact specifics but the baseplate on the LS Edge mag is different to interface with the flared mag well kinda like the HK USP Jet Funnel setup. that and the fact that LS Edge mags are about $80 each. i did get mine when they had the promo with 3 free mags so i have 6 total.I do know that the LS edge full size magazine functions in the CC- interchanged to two myself in the store with the same question. What is different between the 509 and LS Efge mags? I know the FNS mags are comparable with 509 platforms with base plate change.
I have a 509C and a 509 tactical and I have tried to find a sleeve for the 24 round mags that will allow a fit into the 509C and every time I read a description of a sleeve that will cover the magazine to fit the 509C I order it and it doesn't work. Aftermarket is not very good for the 509 pistols.
