Most Helpful Positive Review Good looking extension and functionality
Not only does this extension add +5 to my G17 but the black anodizing compliments my build very well.
Most Helpful Negative Review Be Wary With Glock 22 Mags
Installed two of these onto 15 round Glock 22 mags, .40 cal. While the install was easy (assuming you have the base plate removal tool which you can get on Amazon for 10 bucks), I could not load more than 17 rounds in the mags. I'm also using the new spring included with these baseplates, still no...

Expensive but works for me

by J, from CA, United States Written on January 4, 2026
I’m LEO and wanted extra rounds in my duty gun. I have a flared Magwell and I’ve tried 2 other mag extenders which didn’t work because they were too large and rubbed on the magwell where the flared magwell is. They fit and work. I don’t like the price , the black has coating has already scratched up badly from everyday use.

I’d look at other options if you have a regular magwell

Works great.

by Thomas, Verified Owner from UT, United States Written on December 6, 2025
Very pleased with the plus 5 baseplate with a stiffer spring. Loading the last couple of rounds are a little tough but the spring should break in and last longer.

Junk, and here’s why

by Nate Higgs, from MT, United States Written on August 22, 2025
Yea this part looks good and is made of aluminum, appears to be solid quality. But the inside edges on the channels that slide over the bottom of the magazine are razor sharp and not deburred. It slices into the polymer creating gouges, and causing a rocking side to side motion of about a millimeter. Otherwise I guess it’s not bad.

Excellent product!

by Aarow, Verified Owner from MI, United States Written on July 1, 2025
Great product works and looks phenomenal! It's easy to get on, but watch the video and dont be like me, assuming you can figure it out on your own! If you do, you'll just make yourself look stupid like me!

That being said, installation is still extremely easy!
Pros:
  • Price
  • Function
  • Fit & finish
  • Ease of install
Cons:
  • None
Best Used for:
  • Everything (Not a Hammer)

it holds 5 not 3 lol

by Ben C., Verified Owner from OH, United States Written on October 19, 2024
I assembled this to my factory Glock 17 mag and could only fit 20 rounds in it. I unloaded it and banged the mag around and the spring slid into place. Just a suggestion to people who have the same problem?
Love its ability to drop free so easy with the added weight.
Price is a bit much due to the fact I could find factory Glock 9mm 24 round mags for less.
If you’re a gamer it makes sense with the drop free weight.
