If you run a Ruger P94 in .40 S&W and want more rounds downrange between reloads, the ProMag 20-round steel blue magazine gives you serious capacity without swapping platforms. This extended magazine holds 20 rounds compared to the factory standard, making it a practical choice for shooters who value sustained fire at the range or want a backup mag stack with increased cartridge count. The steel blue construction and reinforced design are built to handle the rigors of regular use.
ProMag engineered this mag with a heat-treated blued-steel body for corrosion resistance and durability. The follower and base plate are molded from a proprietary DuPont Zytel polymer—a material choice that balances weight savings with reliability. That polymer base absorbs impact and helps protect your floor or gear when you're doing mag changes at speed.
The 20-round capacity makes this mag an economical way to extend your P94's firepower without reaching for a different caliber or platform. Whether you're running a dedicated practice session, setting up for a match, or simply want a deep magazine in your rotation, this ProMag delivers straightforward, no-frills capacity for Ruger P94 shooters.
