MILSPIN’s Weighted Brass X-Carve Mag Base Plate adds both functionality and style to your Glock. We want your Glock to not only be one-of-a-kind, but also something you can rely on when you need it most. Whether you’re upgrading a classic Glock 17’s or a modern Glock 43X’s base plate, we’ve got you covered.

This magazine base plate is made with high-quality brass with a black cerakote finish for increased durability. It adds 1.4oz to your Glock’s weight.

From the Glock 21 to Glock 43X/48 Magazine Base Plate, Get the Base Plate for Your Firearm

Everyone has their gun of choice, so we designed the X-Carve Mag Base Plate for yours. We prioritized three things:

  1. Rapid magazine ejection speed. The faster you can reload, the better — especially when your life depends on it.
  2. Increased pistol weight for better stability. By adding an extra 1.4oz, we reduce recoil and improve accuracy.
  3. Looking cool as hell. Our X-Carve texture adds that subtle tactical touch to your loadout while also adding a bit of grip.

That’s not it, though. We stand by our products and give you our 100% satisfaction lifetime guarantee. If it doesn’t meet expectations, your order comes with a no-questions-asked return policy.

First option: Glocks 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 31, 34, 35, and 45

Second option: Only fits the Glock 43X and Glock 48

Third option: Glocks 20, 21, 29, 40, and 41

Choose the option that fits your Glock. For example, the Glock 43X/48 magazine base plate will not fit the Glock 17.

Nice addition to my Glock 17 gen 5. Machining is first class and nicely done. May be a little of an issue to install in place of factory plastic floor plates. But that is due to the Glock design of the floor plate catch on both sides of the magazine bottom . Or if you have arthritis in you fingers as I do . All in all it’s a superb addition.

Great weight. Easy to install. Helps removal with my Mayhall. Love these!

New favorite company

These weighted baseplates really get mags out the gun quick and I’ve noticed also balance out the G48 very well under recoil and makes it more “pointable”.
