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

This product is awesome when they ship you a bag of peanuts MM and tell you by the time you finish eating them the magwell will be install. And that was the truth. It's a nice product is worth the money and I will continue doing business with them.

I couldn’t be happier with my purchase. Got here super quick and looks perfect on my ronin operator. The how to video was super easy to follow as well. Awesome upgrade for the 1911!!

Bought 1 - then another - and plan another
Bought one for a customized 2002 Springfield Loaded - had to adjust the pin hole by a MINOR amount. Liked it so much I bought a second one for a 2011 Colt Combat Elite, PERFECT fit with just a little blending. Again, so Happy, I plan on buying another for my EDC Colt Government. Got to meet Stan and kids at IDPA Nationals. Nice Guy.

Great Fit

Quality Upgrade
It looks almost factory, except for a small chamfer at the bottom rear of my Springfield Garrison. It relieves the sharp corner on the standard flat housing, lines up a mag like butter, and the finish is a near perfect match to the factory bluing. Installation was dead easy, even for a 1911 novice like me. I just followed the video. It's a great upgrade, I'm very happy.

My frame needed to be shortened VERY little for the pin to line up but it’s nice and tight. I just used a piece of sandpaper on a sheet of glass to keep it flat as I removed a few thousands off the bottom of the magwell

Purchased this magwell sometime ago and had it finally installed by a gunsmith due to other issues I had with my pistol. Excellent fit.
