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

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.

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.

Chen SI "Shooter Installed" Magwell
Totally blown away with the quality of the product. The customer service can't be beat either; best I have received anywhere, combined orders to save me shipping and prevented me from purchasing the wrong grips. Can't be beat!

I have ordered 3 of these for Govt model pistols. They are of excellent quality, & the fit is great. I would like to know if you are going to offer these in an Officers model size, 25 lpi, & blued? I would love to have one of these for my DW ECO. Do you plan on making these for the Officers model pistol? Thank you very much

Shooter installed magwell
One of the best magwell products I have ever installed can’t wait to get several more to replace others on compact 1911’s I have. The shape is so clean and elegant I almost want one just to keep on my desk! Fit perfectly and took about 15 minutes to install 2 on different 45’s. Definitely fits my hand better than anything I have used and helps make a carry gun totally snag free.
