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

Shooter Installed Magwell
As always a great product of the highest quality, and the best customer service in the business. It is always a pleasure doing business with Stan and Company. I will be purchasing a couple more of these in the future, the fit and ease of installation is probably the best that I have experienced with one piece magwells.

Do it yourself magwell!
I am not a gunsmith, but have always been in sales and maketing. Accurate product description, great looking product, professional packaging, and the bag of M&M’s was a nice touch. The magwell looks great on my Colt Wiley Clapp. Maybe I’ll save up and buy a complete build.

Chen SI "Shooter Installed" Magwell
Very nice product, and at a great price. Fast shipping and the "bonus chocolate" was a nice treat!! Originally ordered 2 units and installed them the day they arrived. Thinking of ordering another to have on hand for a pistol I am wanting to purchase.

Shooter Installed Magwell
Outstanding machine work and finish. The magwell dropped right into my DW Heritage with no fitting required and no gaps. Everything lines up perfectly and looks amazing. I had never installed one before but the whole process took 8 mins including getting out the tools. I'm extremely impressed!

Awesome
I ordered one SI magwell for my Valor blue and like it so much I ordered two more! You can see and feel the quality of this magwell when compared side by side with others. I love that I get to buy 1911 parts from a Colorado company too, so cool!

Outstanding
All that can be said in my opinion is Outstanding! On quality, craftmenship and customer service. Had some minor fitting isues with my S&W PC1911 but got it worked out with Stans help over the phone. Thanks Chen Customs. All I can say is you better get those machines running 24/7. When my shooting friends here in Texas see this I feel you will be getting swamped. The M&M's were a treat also.
