SKU: WRMESW-5-4P
The Warne Mag Ext S&W M&P 9/40 +5/4 is a magazine extension designed to increase the total ammunition capacity for Smith & Wesson M&P pistols chambered in 9mm and .40 S&W. This accessory adds five rounds for 9mm and four rounds for .40 S&W to the standard factory magazine capacity, enhancing the overall round count without needing a completely new magazine body.
The magazine extension functions by replacing the factory basepad with a longer aluminum or polymer extension that maintains magazine geometry and feed reliability. Installation is straightforward and requires no gunsmithing, making it an accessible upgrade for shooters looking to enhance their magazine capacity for various shooting scenarios.
This extension is particularly beneficial for shooters engaged in higher-round-count training drills, competition stages, or those who prioritize spare ammunition capacity during range sessions. While designed to fit S&W M&P pistols, users should be aware that extended magazines may require holster adjustments for optimal fit.
