I waited about 3 months for my 2 mags and $50. After about 2 months, I sent them an email asking them if they received my paper work. I received an email back saying they did, and gave me my process number. About a month later they both arrived.
Mags for M&P's are impossible to get right now. Who ever is making these things needs to up the production.
