Pro Mag Industries Magazine for Ruger Max-9 Features The ProMag Magazine for Ruger Max-9 is built around a heat-treated steel body finished in black oxide giving it the corrosion resistance and durability needed for daily carry or long-term storage. Its 10-round capacity matches the Ruger Max-9 s factory magazine specification making it a genuine drop-in spare rather than an aftermarket compromise. The injection-molded follower is designed to track smoothly through the magazine body helping keep feeding consistent from a full magazine down to the last round. A heat-treated stainless steel spring rounds out the internals providing the reliable spring tension a defensive magazine depends on. Made in the USA this magazine gives Ruger Max-9 owners a domestically produced option for expanding their magazine supply beyond what shipped with the pistol. Having extra magazines on hand is valuable whether the pistol is used for concealed carry home defense or range practice since a spare keeps the gun running while a backup stays loaded and ready. The black oxide finish also helps the magazine resist the wear that comes from repeated insertion and removal from a holster or magazine pouch. For Max-9 owners looking to add a reliable purpose-built spare this magazine is a straightforward choice.
