This is the new factory Smith & Wesson M&P FPC 9mm 23 Round Magazine. 

These versatile high-capacity factory magazines from Smith & Wesson were designed for the new M&P FPC (folding pistol carbine) but are also compatible with the new S&W Response and other select M&P9 pistols.

With a stainless-steel body and a corrosion-resistant finish, durability will never be a cause for concern. Inside the magazine is a polymer follower on top of a high-tensile steel spring that delivers smooth and reliable feeding. 

A polymer grip adapter spacer is included to provide a flush fit and seamless aesthetic. Additionally, the magazine features side-facing numbered witness holes to provide a quick and easy visual round count.

The FPC would make a fantastic truck or backpack gun, given its higher capacity and folding ability. In both of those scenarios, the more rounds you have at your disposal, the better. That’s where these 23-round factory magazines can help. 

Since the FPC features in-stock magazine storage for up to two additional magazines, buying just one wouldn’t make sense. Add a couple to your cart and prepare for a fully loaded FPC!
