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
I won my first SI Magwell through an IG giveaway. I loved it so much I had to purchase another one. Absolutely the best Magwell on the market. I’m a shooter not a gunsmith. If I can install it anyone can. There will definitely be more SI magwell’s in my future. Especially when the SI little brother comes out. Awesome product.

SI Magwells
I've installed two SI magwells. 1) Stainless steel onto a stainless steel Dan Wesson Valor. Had to do minor fitting to the magwell mainspring housing (remove metal). SI finish matches the Valor bead blast extremely well. 2) Blued steel onto a Dan Wesson Silverback. Slid right on needing no fitting. Fits tight against the bottom of the grip frame. The SI blueing is essentially black and matches the Dan Wesson Duty Treat (black) extremely well. I really like the rounded mainspring housing bottom edge on these SI's since they don't dig into my skin. Additionally all my various mags had no interference's when installed into the mag well.

Kimber Stainless 2 SI Magwell
Mr.Chen!!! Man Oh Man...you have made the perfect drop in part! The SI Magwell fit right in very easily. My pistol looks 100 times better! Infact I think it's the best looking part on my pistol. I might need to send it in to you to match the beautiful part I just purchased and installed. LOL Great price, fast shipping and made in the USA! Nothin' better than that! Thank you!

The craftsmanship, finish, and checkering are top notch. It fits very well, magwell rear contour is excellent, and slims it down just right.

best deal on the market
great fit and finish. Matched up to my SIG super target perfect. Bonus that the checkering is so much better than the stock mim part on the SIG. Every 1911 I buy from now on will get a Stan Chen mag well. Next up a pair od Tac Opps in 10MM
