Description
When the clock's running and your fine motor skills go out the window, a good magwell is the difference between a clean reload and a fumbled one. The Shield Arms Premium Magwell is built for exactly that kind of pressure, giving your Gen 5 Glock 17, 22, or 45 a big, forgiving funnel that guides magazines right into place. This is the full-funnel design in the Shield Arms lineup, so if raw reload speed is what you're chasing, this is the one.
What Makes the Premium Magwell Tick
It's CNC-machined from 6061-T6 aluminum, the same aerospace-grade billet Shield Arms uses across their magwell line, then finished with a Type-2 anodized coating for durability. The wide opening is the star of the show, but the contoured shape also adds a bit of extra real estate to grab onto, which helps lock in your grip during recoil. Whether you're running S15 magazines, OEM Glock mags, or Shield Arms extensions, it plays nice with all of them.
Installing the Shield Arms Premium Magwell
No gunsmith needed here. It's a drop-in job with the included hardware, and most folks have it buttoned up in under ten minutes. Keep in mind this is cut for the standard grip, so if you want to keep running a backstrap you may need to do a little trimming to make room.
Built for the Match, Ready for the Range
This magwell was designed with USPSA, IPSC, and IDPA competitors in mind, where shaving tenths of a second off every reload adds up over a stage. That said, plenty of people bolt one on for high-volume range days and training too, since faster mag changes are just plain useful. Made in Bigfork, Montana and backed by a lifetime warranty, it's the kind of upgrade you install once and forget about.

Frequently Asked Questions
Will the Premium Magwell fit my Gen 5 Glock 17?
Yes, it's cut specifically for the Gen 5 Glock 17, along with the Gen 5 Glock 22 and 45 full-size frames. It will not fit Gen 3 or Gen 4 frames, since those use a different backstrap and grip geometry. Double-check your generation before ordering.
How hard is the Shield Arms Premium Magwell to install?
It's a drop-in installation using the included hardware, and no gunsmithing is required. Most people have it mounted in under ten minutes with basic tools. If you want to keep running a backstrap on your Glock, you may need to trim it slightly to clear the magwell.
What's the difference between the Premium and the Carry magwell?
The Premium is the wider, full-funnel design built for maximum reload speed in USPSA, IPSC, and IDPA competition. The Carry version has a slimmer, low-profile funnel meant for concealment and duty use. If you want the biggest opening for the fastest mag changes, the Premium is your pick.
Does the Premium Magwell work with my extended magazines?
It does. The Premium Magwell is compatible with OEM Glock magazines, Shield Arms S15 magazines, and Shield Arms +5/+4 extensions. That makes it a solid match whether you run standard mags or squeeze in the extra rounds for a match.
