msg73 1 Posted December 11, 2014 I'm looking to get an open and possibly limited 2011 gun but have no idea how to get the mags for it. Specifically, I would like some 140mm STI mags with it pinned appropriately (e.g. riveted?) to limit it to 15rds. What can I do? Quote Share this post Link to post Share on other sites
NYMetsFan86 9 Posted December 11, 2014 you can find a sight that will let you have the mags shipped to an FFL dealer, then that dealer can permanently block the mags for you. I know Steve from Monmouth Arms does this. Quote Share this post Link to post Share on other sites
ronhonda 86 Posted December 11, 2014 RTSP has 15 round mags And they are a STI dealer. Quote Share this post Link to post Share on other sites
raz-0 1,256 Posted December 11, 2014 For 40, 126mm mags = 15 rounds no pinning needed. Quote Share this post Link to post Share on other sites
