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

Outstanding 1911 Magwell (3rd purchase)...
Simply an outstanding well made one-piece mainspring housing and magwell that installs and functions flawlessly. I have one on a Smith & Wesson, Springfield Armory, and now a Sig Sauer 1911, and they are all running great with no modifications necessary. A highly recommended addition to any full size 1911.

I would love to give you a review but I haven’t received my order yet. It’s been weeks and still haven’t gotten it. You’re website doesn’t have a contact phone number either.

Magwell
Installed on my new Springfield Operator. The fit was perfect. The color match was also perfect. Honestly, I was worried when the description said “blued “so I sent an email asking if it would match, the black matte finish of my operator. The response was very timely. I received the magwell very shortly there after and it did match. Installation was a breeze. I added new flat bottom VZ grips to complete the look. Side note. I have VZ grips on all my 1911s and I agree with Stan, they really do complete the look.

Second time buyer of this outstanding one-piece 1911 magwell. Completely problem-free and an absolute breeze to install as a true drop-in mainspring housing & magazine well for my 1911's. Highly recommended for it's fit, finish, and overall quality. Looks awesome and performs flawlessly. I will be purchasing another for my next 1911 project. Many Thanks!
