Current Beta Version: 0.1

Fully printable +4/5 (depending on springs used) magazine extension designed to be directly compatible with the S&W M&P 9 Competitor, with the factory flared mag well. It should work fine with any other M&P9 model, however. It's also meant to be 140mm USPSA compatible. If you're interested in helping with the beta, find me on Element.
