ProMag Tisas PX-57 Handgun Magazine 5.7x28mm 20/rd

The ProMag Tisas PX-57 Handgun Magazine is a 20-round replacement magazine built specifically for Tisas PX 5.7 pistols chambered in 5.7x28mm. It gives PX 5.7 owners a dependable full-capacity feeding source for range days training and everyday carry loadouts and it does so with a durable all-steel body engineered to take repeated loading seating and rough handling. For a caliber that thrives on high round counts having extra 20-round magazines on hand keeps you shooting instead of reloading.

Fit and function are the whole point of a magazine and this one is dedicated to the Tisas 5.7x28mm platform rather than a one-size-fits-all design. Because it is dimensioned for the PX 5.7 it drops in locks up and feeds the same way your factory magazine does which makes it an easy choice for shooters who want backups that behave predictably. The 20-round capacity matches the intended layout of the pistol so you get consistent stack pressure and reliable presentation of each 5.7x28mm cartridge to the chamber.

Construction is where this magazine earns its keep. The body is formed from heat-treated steel and finished in protective black oxide a combination that resists wear and corrosion while standing up to the daily grind of a working magazine. Inside an injection-molded follower guides rounds smoothly and consistently to prevent misfeeds. The magazine spring is formed from heat-treated chrome silicone wire for lasting resilient tension that holds up over thousands of compression cycles. The result is a magazine designed to feed as confidently on its five-hundredth load as it does on its first. It is also proudly made in the USA.
