Hi all, I recently bought a sti branded conversion kit and I got 4 magazines to go with it. However de magazines only hold 10 rounds and probaly 9 for real. I have been doing a lot of research this week and the information is very limited. I would like to upgrade the capacity of my magazines. Is there anyway i can do this? For instances can I use diffrent Baseplates and if so what kind? Or can I do some modifications on the follower?
