Strike Industries Polymer Magwell for Glock 19/23 Gen 3 - Black

The Strike Industries Polymer Magwell for Glock 19/23 Gen 3 is a flared magazine funnel designed to speed up reloads and improve handling during rapid-fire strings. Built from Strike Industries' custom-blended SI Polymer Extreme material, this magwell resists impact and keeps the frame's original slender profile intact—so you get faster magazine insertion without sacrificing conceal-carry comfort. Whether you're running drills at the range or training for defensive scenarios, this accessory cuts the margin for error during emergency reloads.

Installation is straightforward: the magwell attaches via a single set screw (included, along with the hex key), and the flared design works with most aftermarket magazine base plates and extensions. Strike Industries specifically engineered this to pair seamlessly with their Extended Magazine Plate (EMP) for the G19. The funnel geometry helps prevent the common reload bobble—that moment when a magazine slides past the magwell instead of seating cleanly—giving you the consistency you need when every second counts.

This is a Glock Gen 3 platform part, so verify your pistol generation before ordering. Note that it is not compatible with 10-round Glock magazines paired with Strike Industries aluminum base plates. As with any frame modification, avoid overtightening the set screw; improper installation can misalign the magwell or damage the firearm. When in doubt, consult a qualified gunsmith.

Can I install this myself, or should I use a gunsmith?
