FACTR Glock® Magwell for G19 Gen3-4

(27 reviews) Write a Review

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
  • Extended Basepad-compatible
  • Gen5 magazine compatible (Gen5 magazine baseplate will not bottom out before engagement, 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
  • Red
  • Gray

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

Typically, use with restricted state 10rd (or fewer) magazines will require aftermarket basepads designed to work with magwells. Check out our FACTR +0 Basepads here.

    Glock gen3 magwell

    Posted by Justin on Mar 24th 2023

    Just pick up my magwell and was Quite impressed with quality and fitment of this product. The ergonomics is outstanding in the hand and it actually improved my accuracy on the range and I was also pleased to see that it dosen't add additional printing "" for concealment I thought this would be a issue but not with this magwell. If your looking for a quality product it's well worth the$$.

    Perfect fitting magwell

    Posted by Charlie on Oct 24th 2022

    This magwell eliminated the gap I had with my previous magwell. The esthetic is amazing now and the magwell helps align my grip as my pinkie finger rests at the bottom of the magwell. Love it!

    The magwell really changes the feel of the pistol in your hand, I love it! Also it's not over bulky... The fit is great and it looks amazing too!

    Perfect Fit

    Posted by Kevin B. on Jun 13th 2022

    Installed on my Glock 23 gen 4. Fit and quality was perfection. No sharp edges, nothing to sticking out in magwell to interfere with loading. Love this product. Would definitely recommend.

    Awesome magwell

    Posted by kurtis on Apr 28th 2022

    I was looking for a magwell that could accomodate my taran tactical magazine extensions, and stumbled upon this magwell. After comparing the aesthetics of various gen 4 19 magwells, I settled on this one. It's probably the slimmest profile out there that is aluminum. The appearance of it definitely sets it apart too. Everything installed without issue and fit properly with my backstraps installed. Wouldn't hesitate to buy another one of these if I needed another.

    Needed a magwell that worked with Glock backstraps. If you're looking for the same, look no further. This magwell is extremely well made, fits perfectly, looks and functions great. I read all of the reviews before purchasing and can now echo everything else that has been said about this. Buy with confidence. Thanks FACTRUSA.
