The ProMag TAU21 extended 8-round 9mm magazine for Taurus 709 Slim gives your everyday carry or range sessions more runway between reloads. If you carry or train with a 709 Slim, you know that factory capacity sometimes feels tight—this extended mag steps up without dramatically increasing your profile, and the steel construction means it'll handle the wear that comes with active use.
Built from heat-treated carbon steel with a black-oxide finish, the TAU21 resists corrosion and stays reliable through regular carry, storage, and shooting. The magazine houses a chrome-silicon spring and injection-molded follower designed to feed 9mm rounds reliably, so you can focus on your shot process instead of worrying about malfunctions. Made in the USA, these magazines undergo the durability testing ProMag applies across their line.
Whether you're stocking spares for your EDC rotation, adding capacity for range days, or building a backup magazine supply, the 8-round capacity of the TAU21 strikes a practical balance—it extends your on-board round count without the bulk of the 10-round option. The extended body also provides a more comfortable grip purchase, especially useful if you have larger hands or prefer a more stable mag for administrative reloads.

Frequently Asked Questions
Will this ProMag magazine work with my Taurus 709 Slim?
Yes, the TAU21 is designed specifically for the Taurus 709 Slim and chambers 9mm rounds. Make sure you own a 709 Slim before ordering, as this magazine is not compatible with other Taurus models or calibers.
What's the advantage of the 8-round over the 7-round factory magazine?
The 8-round extended capacity gives you one additional round without the bulk of the 10-round option. The extended body also provides a longer grip surface, which many shooters find more comfortable and stable for reloads and control.
Is this magazine suitable for everyday carry?
Yes. The 8-round capacity is a practical balance between added capacity and concealability. The steel construction and black-oxide finish are designed to withstand regular carry and use in an EDC rotation.
Can I use ProMag TAU21 magazines for both range practice and duty carry?
The TAU21 is built tough enough for both applications. Its heat-treated steel construction and corrosion-resistant finish make it durable for high-round-count range days and reliable for carry use.
