Most Helpful Positive Review Great magwell for Shield magazine users
Great magwell for Glock 43x and Shield mag users. Adds a little bit of circumference for easier mag changes. Price is a bit high, but is a perfect fit for Shield mags, no problems seating or extracting mags.

Didn’t work for me.

by Dunk, Verified Owner from GA, United States Written on June 13, 2026
I’m giving this three stars because it is very well made from high-quality materials. Unfortunately, I could get it to mount securely to my 43X MOS. That could be on me, but for this price, I would expect this to stay securely mounted. I do have friends with the same product that have no issues with it. Just didn’t work for me.
Pros:
  • Quality Materials & Craftsmanship
Cons:
  • None

Fits Perfecly and increases grip

by MTH, Verified Owner from OH, United States Written on February 19, 2026
The magwell is anodized aluminum and the grip insert is plastic with a metal insert for the screw.
Contoured for increased grip when coupled with the shield arms S15 magazine baseplate.
This carry magwell has a much slimmer profile compared to the premium magwell that has a full profile
but still allows for faster, more positive reloads and provides a little extra leverage for a better grip.
Installation was quick.
Pros:
  • Works well with Shield Arms S15 mags
  • Better grip and mag changes
  • Easier mag changes
  • No modifications needed to install
Cons:
  • Installation is easy but takes a moment or two to get it in the right spot
  • Oem mags will work but not easy to grap the mag baseplate if needed. But you wouldn't probably be using OEM mags if using the S15 mags
Best Used for:
  • concealed carry
Would recommend: Yes

Great magwell

by Daniel Hamilton, Verified Owner from GA, United States Written on January 16, 2026
Usually on Glocks, I get caught on that plug hole behind the magwell when doing quick reloads but with this guy it’s really crisp smooth. Small profile keeps it very concealable and gives your pinky a good spot to rest. Highly recommend.

Functional yet low profile

by JM GlockandSig, Verified Owner from NC, United States Written on January 13, 2026
Definitely makes reloads easier, also push’s your hand up to improve grip. Easy to shoot tighter groups. Two thumbs up

Sent back to manufacture

by PNP, Verified Owner from NY, United States Written on January 19, 2025
Received the magwell and the inside threads were stripped. Refused to accept the included screw. Immediately sent back to the manufacturer. Not pleased with the QC of it leaving the factory. Zero issue with optics planet. Not pleased with the product.

Subtle magwell

Small and functional

by Wolvesden509, Verified Owner from WA, United States Written on December 17, 2024
Quick and easy upgrade. The inside edges line up perfectly and the fit is snug. Very functional ramp for its size. Doesn't create an unnecessary bump at the pinky or adversely impact grip like some larger magwells do. A little pricey but that's because it's aluminum vs polymer.
Pros:
  • Size
  • Easy to install
  • Fit
Cons:
  • price

Glock 48 MOS upgrade.

by John Farill, Verified Owner from TN, United States Written on July 10, 2024
I recently purchased this product from OpticsPlanet. I really think I made the best choice. The magwell installs very easily and really facilitates the use of my Shield Arms mags. By here with confidence.
