ProMag S&W M&P45 Magazine - 13 Round
The ProMag SMI-A16 is a 13-round replacement magazine for the full-size Smith & Wesson M&P 45 chambered in .45 ACP. The body is built from heat-treated steel with a blued black oxide finish, paired with a heat-treated chrome-silicon wire spring and an injection-molded Zytel polymer follower for dependable feeding. An extended polymer base plate adds three rounds over the standard 10-round factory mag without affecting fit. A solid pick for range training, competition, and home-defense spares for the M&P 45 platform. Does not fit M&P 9mm, M&P Shield, or Shield EZ pistols.

Feed exceptionally wellI recently purchased two of these magazines after looking online for a model that holds more than 8 rounds. They feed exceptionally well. The only minor issue I encountered is that they don't fit perfectly but they're very close. Additionally, I got two of these extended magazines for the price of one Smith & Wesson extended magazine. Thank you, guys! I love them!
