ok. ive done some research on the 12rd'ers with some luck, but still have some questions. i'm gonna start from scratch, so please excuse my ignorance. 1. does steyr make or sell stock s9 12rd. magazines? if not, they should. anybody know if they're gonna be making them in the future if they don't already? 2. what is the difference between the followers, baseplates, springs, and magazine bodies for all steyr mags? i.e. m9 14rd, s9 10rd, s40 10rd. 3. could i make a 12rd'er from existing s9 10 rd mags? just replace the baseplate with an m9 14rd baseplate? (if the baseplate in the s9 mag is taller.) 4. are the followers in 9mm mags different from .40 caliber mags? 5. to those who have done it, what does your s9 12rd mag consist of? i.e s40 mag body, s40 spring, m9 baseplate, s9 follower. im asking this because im horrible at altering feedlips. i have a tendency to overdo it. :roll: id love to find a way to do it without altering anything except swapping parts. HELP!!
