FACTR™ Glock® Magwell for Gen3-4

In the search for an effective magwell to run on our carry guns without drastically increasing the profile and size of the bottom of the grip, we kept coming up short. Too wide. Too tall. Funnel too small. Not enough funnel angle at all. Poor grip enhancement. Ugly as sin. That's when we decided that FACTR needed a magwell of its magwell to rule them all...just kidding. However, we believe the FACTR Magwell checks all of the boxes in the search for an effective and concealable CCW magwell. It adds significant reloading functionality with a minimal EDC footprint. It also provides grip enhancement by giving the user a comfortable index ledge for the hanging pinky...more of that digital comfort you've come to expect from us.

This is how:

  • 6061-T6 Alumin-i-um (said with our best Jony Ive voice)
  • Functional 50° funnel angle
  • Approximately 48% increased opening over stock
  • Contoured grip optimization
  • Generation-specific flush fit grip plug
  • Flush plug mounting screw at rear of grip
  • Locking Heli-Coil threads for magwell-to-plug attachment screw provides secure and worry-free interface
  • Backstrap-compatible
  • Less than 1/4 in. increase in overall grip width
  • Approximately 1/8 in. increase in overall grip length
  • TTI Base Pad compatible
  • Gen5 magazine compatible (run Gen5 mags with your Gen3-4 guns)
  • High-quality hard anodized finish delivers durability and that "buttery" soft feel
  • MADE IN USA (the only way we do it)


  • Black

Compatible with Glock® G19/23 Gen3 or Gen4 ONLY (Must choose correct generation to receive correct plug)

    Best concealment magwell

    Posted by Sean on Oct 7th 2020

    Precise fit. No ledges that will snag your mag during reloads. Slimmer profile than the Zev and SLR magwells.

    Love the design of this magwell, has a nice slim profile and guides the mags right on in.

    Excellent design and quality. The maximized magwell funnel, low profile design, and enhanced grip makes this a great option for carry. A great product from FACTR!

    FACTR Magwell

    Superior design and manufacturing. This magwell has given me consistency in my grip when drawing from concealment and from my Safariland duty rig. Reload split times have decreased 30%. Those benefits all with little to no printing when carrying AIWB. Best I have ever used.

    Best CCW Magwell on the Market

    Posted by Josh Preston on Jul 9th 2020

    This is hands down the best ccw magwell on the market. The footprint is extremely minimal without taking away from the functionality. The fit and finish are exceptional like all FACTR products!
