Description
If you're running the Kimber R7 Mako, you already know the gun is capable. What a lot of people discover after a few range sessions is that the biggest limitation isn't the pistol itself — it's getting a full grip with the shorter magazines. That's exactly where this 15-round extended magazine changes things. The grip extension adds meaningful length below the frame, enough to get all four fingers solidly on the gun instead of leaving your pinky floating. Folks with medium to large hands especially notice the difference, and the feedback from owners who've made the switch is pretty consistent: groups tighten up and the gun just feels more confidence-inspiring to shoot.
Construction-wise, this is a factory Kimber magazine, not an aftermarket guess. The body features aluminum construction with a corrosion-resistant finish, paired with a high-visibility blue polymer follower and a steel wire spring for reliable cartridge feeding. Numbered witness holes let you do a quick round count at a glance, which is a small thing that matters more than most people expect until they're standing on a range with a loaded gun.
The 15-rounder also ships with a textured grip sleeve that wraps around the extension for a better hold during shooting. It fits flush and functions cleanly in the R7 Mako platform — this isn't a mag that needs coaxing to seat or drop free. It's a factory part made to factory specs.
This magazine is a smart pickup whether you're adding to your rotation for range days, keeping a spare handy, or just prefer the feel of a fuller grip for your carry setup. One magazine is included per package.

Frequently Asked Questions
Will this 15-round magazine work in all R7 Mako models?
This magazine is designed specifically for the Kimber R7 Mako pistol platform. It is compatible with standard R7 Mako models. If you're running the R7 Mako Carbon Compact, that model uses a different magazine (MPN 1700175A), so double-check your specific variant before ordering.
How much longer is the 15-round magazine compared to the standard 13-round mag?
The 15-round extended magazine extends roughly 1 to 1.25 inches below the grip frame compared to the standard 13-round magazine. That extra length is enough to give most shooters a full four-finger grip instead of leaving the pinky off the gun, which makes a real difference in control and recoil management.
Does the grip extension on this magazine affect concealed carry?
It adds a small amount of overall height to the pistol, so it can print slightly more under a garment compared to the flush-fitting 11-round mag. That said, plenty of R7 Mako owners carry the 15-rounder IWB without significant issues, especially with a good holster. It comes down to your body type, carry position, and wardrobe.
Is this a factory Kimber magazine or an aftermarket product?
This is a factory original Kimber magazine, manufactured to the same specs and tolerances as the magazines that ship with the pistol. It features the same aluminum body, blue polymer follower, steel wire spring, and numbered witness holes you'd find in a factory-packed R7 Mako.
What is the grip sleeve on this magazine and can it be removed?
The grip sleeve is a textured polymer sleeve that wraps around the magazine extension to provide a better grip surface during shooting. Some owners remove it for a slightly lower-profile look or feel. It slides off without tools, so you have the option either way.
How many of these magazines should I own?
For range use, having at least two or three magazines makes for a much smoother session without constant reloading. For anyone carrying the R7 Mako for personal protection, having a minimum of two loaded and ready is a reasonable baseline. Magazines are consumable items over time, so having spares on hand is always a good call.
