The SI Magwell is the latest addition to the Stan Chen Custom Magwell family. It delivers greatly enhanced reloads, elegant design and maximum durability.
Solid, one piece construction.
Large sculpted funnel for dramatically faster reloads. Through careful CAD design, every last millimeter of available real estate was turned into reload-enhancing surface area.
Designed to very nicely match the beveled magazine wells commonly found on current production 1911s, such as Springfields, Kimbers, Dan Wessons and current Colts (2018 production with fully beveled magazine well) .
Most Colts made prior to 2018, and other frames without full magazine bevels, will require minor blending. (See pictures above). We offer a "Blend Kit" to facilitate this (located under "Accesories").
Eliminates sharp frame corners. Unique funnel profile eliminates sharp edges at front of magazine well opening on the frame. Smoothing of all surfaces on the entire part yields total carry comfort.
Low profile roundbutt. Flowing design. The lines of the entire magwell were designed to flow well with the pistol, giving the bottom of the pistol a cohesive, custom look.
Custom quality checkering. Equaled only by the very best gunsmiths. Perfectly formed diamonds, row after row. Even at 20x magnification. Enhances recoil control.
One-Piece Durability. Precision CNC machined from a solid block of heat treated steel. No joints or screws to work loose, ever.
Made in-house at Stan Chen Custom, Durango, CO, USA

Great piece with a great fit. Would have given 5 stars but the finish on the checkering on the last row could be better. The cut run a bit long. A boarder on the bottom row would finish this piece very nicely

I own 3 SI Magwells that should tell ya what you need to know.
Put a SS MWell on my Magnum Research 1911, about a 97.5% perfect match up with the frame. Well done Mr. Chen, well done. My daughter thnx you for the M&Ms. Thnx.

Wow! The best!
I am getting ready to take down Stan's buddy Lance Barrick on mag reload time. You can view Lance's mag reloads on Stan Chen's Facebook page. The SI Maxwell is great!
