Description
When it comes to magazines, factory OEM is always the safest bet. This 10-round magazine is made by Taurus specifically for the G3C in .40 S&W, so you're not rolling the dice on aftermarket fitment or feed reliability. It drops in and functions exactly the way the pistol was designed to work.
The body is stainless steel with a corrosion-resistant black finish, which gives it solid durability whether it's riding in a range bag, sitting in a nightstand, or getting cycled hard during training sessions. The steel wire spring and durable polymer follower work together to keep rounds feeding smoothly and consistently, even after repeated loading and unloading.
A few features here are genuinely practical rather than just box-checking. The numbered witness holes along the spine let you do a quick round count without having to drop the mag and count by feel. The polymer pinky extension at the baseplate adds a bit of grip surface, which makes a real difference on a compact pistol where your pinky might otherwise be floating.
This is a solid pickup for anyone who wants a reliable spare to rotate in during range sessions, or for G3C owners who carry and want a backup ready to go. One magazine is included.

Frequently Asked Questions
Is this a factory Taurus magazine or an aftermarket one?
This is a genuine OEM factory magazine made by Taurus, part number 358-0029-00. It is manufactured to the same specifications as the magazine that came with your G3C, so you can expect the same fit and function right out of the box.
Will this G3C magazine work with .40 S&W G2C pistols?
There is some reported interchangeability between the G3C and G2C magazine lines, as the two platforms are closely related. That said, Taurus designates separate part numbers for each model, so for guaranteed fitment we'd recommend using the magazine designated specifically for your pistol.
What does the pinky extension do on this magazine?
The polymer pinky extension at the base of the magazine gives your bottom finger a place to grip on a compact-frame pistol, which improves overall control and makes reloads feel more natural. It is a small but noticeable improvement in handling, especially for shooters with larger hands.
How do the numbered witness holes work?
The witness holes are small openings cut into the side of the magazine body, each marked with a round count number. They let you see at a glance how many rounds are loaded without pulling the mag or counting by hand, which is useful during range sessions and when doing a quick chamber check before carry.
Is this magazine suitable for everyday carry use?
Yes. The stainless steel body with corrosion-resistant finish holds up well to the humidity and wear that comes with regular carry use. Many G3C owners keep one loaded as a spare and rotate through it at the range to maintain spring health and ensure it stays functional.
What is the capacity of this magazine?
This magazine holds 10 rounds of .40 S&W ammunition. It is a flush-fit design intended for the compact G3C frame, making it a practical option for both carry and range use.
