Built Different Where It Counts
Precision Funnel Geometry
The funnel guides the magazine into the well faster and more consistently than the factory grip frame.
Drop-In, No Gunsmithing
Installs with the included hardware in under ten minutes, and comes off without any permanent change to the frame.
Runs Your Mags
Works with OEM Glock magazines, quality aftermarket mags, and Shield Arms magazines and extensions.
Covered for Life
CNC-machined from 6061-T6 billet, Type II anodized, and backed by our lifetime warranty.
Faster In, More On Board
A magwell speeds up the reload, and an extension adds rounds to the magazine you're reloading with. Glock 43X/48 owners can get both in one box with an S15 Magwell Combo.
Carry or Premium: Which Magwell Do I Need?
Shield Arms makes two magwell profiles, both CNC-machined from 6061-T6 aluminum in Bigfork, Montana, Type II anodized, and backed by a lifetime warranty.
- Carry Magwell: a low-profile funnel with minimal added bulk, built for concealed carry, EDC and duty.
- Premium Magwell: the widest funnel opening Shield Arms offers, built for duty, USPSA and IPSC, where reload speed matters most.
- Both are drop-in with included hardware and require no gunsmithing.
- Each magwell is cut for a specific frame and generation, so match your pistol before ordering.
Magwell FAQ
Does a magwell work with extended magazines?
Yes. Both profiles run OEM Glock magazines, quality aftermarket mags, and Shield Arms magazines with standard or extended baseplates, including our mag extensions.
Does generation matter?
Yes. Gen 6 frames use different geometry than Gen 5, so each magwell is cut for one generation. Gen 6 magwells are not compatible with backstraps.
How hard is installation?
Drop-in with the included hardware, usually under ten minutes, no gunsmithing. Step-by-step guides are on our installation page.
Can I use one in competition?
Yes. The Premium Magwell is cut for USPSA and IPSC reload speed. Check your division's current rulebook for magwell limits before a match.
