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

SI Magwell Kimber Warrior 2
Great magwell perfect fitment with the frame and grip. Due to the swartz grip safety on the Kimber model 2's I did have to file a few millimeter off the part that makes contact with the grip safety tang. If you don't the firing pin safety plunger will stay up and you won't be able to remove the slide. Took around 30 mins for the whole job. File and fit file and fit re blued and installed.

super easy!
I have a custom built 1911 that was complete except for a magwell. This makes it look complete. The lines inside and out are perfect!

Excellent fit on my Springfield Loaded 9mm 1911
The fit and finish of this "shooter installed" magwell was perfect on my Springfield Loaded Target 9mm 1911. The bevels lined up perfectly with the factory bevel in the frame. Loading magazines is a breeze now and once I added bump pads to my magazines, eliminated the inside of my hand getting pinched between the frame and the magazine during loading. Speed loading a magazine without looking is a breeze. Highly recommend this Stan Chen SI one piece magwell. Easy to install, very strong, and the quality is unsurpassed. Required zero modifications to install.

SI magwell
Bought 2. 1 for a 1911 Springer MC Operator 45 and 1 for a 1911 Springer Stainless target. Perfection. You can't tell it's a drop in part. NO fitting necessary. Love them.

Drop-in mag well
I was really impressed with this mag well. No fitting, slid right in, looked like a quality piece of gun parts. Thinking about getting one for another 1911. Would buy again.
