Pro Mag Industries Magazine for S&W M&P10 Features The ProMag Magazine for S&W M&P10 holds 20 rounds of 10mm Auto and is built specifically to fit the Smith and Wesson M&P 10mm series of pistols without fitting the M&P 9mm Shield 9mm Shield Plus 9mm or Shield EZ 9mm models. Heat treated steel construction gives the magazine body the strength to withstand repeated loading and unloading while the black oxide finish adds a layer of corrosion resistance for long term storage and field use. An injection molded follower keeps rounds feeding smoothly and consistently from the first round to the last. This combination of materials keeps the magazine functioning reliably across range sessions and duty carry alike. A heat treated chrome silicone wire spring provides the tension needed for dependable feeding a detail that matters most as the magazine nears full capacity and the spring works hardest. ProMag builds this magazine in the USA keeping manufacturing standards consistent and quality control tight across the production run. Owners of M&P 10mm pistols looking to add spare magazines for range use training or backup carry will find this a straightforward affordable option. The 20 round capacity gives shooters extra rounds on hand for extended range sessions or competition use.
