Description
The Kimber Micro 9 is already a well-regarded carry pistol, and the TACMAG takes the magazine game up a notch compared to the standard flush-fit option. This is a factory Kimber magazine, part number 1200851A, built specifically for the Micro 9 platform (note: it is not compatible with Micro 9 RAPIDE models, which use a different magazine). You get 7 rounds of 9mm in a stainless steel body that holds up well to the wear and sweat that comes with everyday carry.
The big upgrades over a standard mag come from the inside out. A Teflon-coated follower reduces friction as rounds feed into the chamber, and the chrome-silicon alloy steel spring is engineered to maintain consistent tension over time. The result is reliable feeding whether you're running 115gr FMJ at the range or your preferred hollow point for carry. The finger extension at the base adds a noticeable difference in grip purchase, especially for shooters with larger hands who find the standard Micro 9 frame a bit snug.
The stainless body also features witness holes so you can get a quick round count at a glance, and the overall fit and finish is exactly what you'd expect from a factory Kimber product. Whether you're picking this up as a carry spare or just want a more ergonomic option loaded in the gun day-to-day, the TACMAG is a practical upgrade that doesn't change the footprint of the pistol in any meaningful way.

Frequently Asked Questions
What Kimber Micro 9 models is the TACMAG compatible with?
The TACMAG 1200851A fits the standard Kimber Micro 9 series chambered in 9mm. It is not compatible with the Micro 9 RAPIDE models, which require a different magazine. If you own a RAPIDE, Kimber makes a separate TACMAG version specifically for that platform.
What is the difference between the TACMAG and a standard Kimber Micro 9 magazine?
The TACMAG adds two key upgrades: a Teflon-coated follower for smoother feeding and a chrome-silicon alloy steel spring designed to hold its tension longer than standard spring wire. It also includes a textured finger extension at the base that gives you more grip surface on the pistol, which makes a noticeable difference on a compact frame like the Micro 9.
Will this magazine change how the Micro 9 prints or fits in a holster?
The finger extension does add a small amount of length to the grip compared to a flush-fit magazine, so it's worth checking holster fit before carrying. That said, the extension is modest and many IWB holsters designed for the Micro 9 will still accommodate it. When in doubt, test the fit before heading out.
Is this a factory Kimber magazine or an aftermarket product?
This is a 100% factory OEM Kimber magazine, manufactured by Kimber under part number 1200851A. You're getting the same fit, finish, and quality control that comes with the pistol itself, not a third-party copy.
What grain ammunition has this magazine been tested to run reliably?
The TACMAG is designed to feed standard 9mm Luger ammunition across a typical weight range. Real-world use has shown reliable cycling with both 115gr FMJ and various hollow point loads ranging up to 147gr. As with any carry magazine, it's always a good idea to test your chosen carry load before trusting it.
Does the TACMAG have witness holes to check round count?
Yes, the stainless steel body includes witness holes so you can get a quick visual on how many rounds remain without stripping the magazine. It's a small but useful detail, especially when checking status quickly during a range session or at home.
