The Smith & Wesson M&P45 magazine is a factory original replacement magazine designed to increase the capacity of the M&P45. The 14-round magazine holds four additional rounds of .45 ACP over the standard magazine, and compensates for the additional length with an ergonomic Grip Extension Sleeve. The Military & Police (M&P) magazine is made of steel and polymer and is made to Smith & Wesson's specifications and tolerances, using the same manufacturing and materials as the original equipment magazines to ensure perfect fit and operation. |
