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

The fit and finish on this part are superb. I am really impressed by the quality of the checkering and the roundbutt profile. The part fit perfectly on my Colt Gold Cup Trophy.

This magwell is excellently made. It feels better in my hand than the manufacturer's magwell. Thank you for an excellent product!!

SI magwell
The finest magwell ever made, period! My carry cover is either a wool or canvas vest. The other magwell I used wore the vest out. These wells are smooth on the heel, and fast in the reloading department, when fitted correctly to your firearm. I have fitted all my carry guns to this well. I have bought six.

Quality
I have a Dan Wesson specialist; fits great and didn't need any filing or anything. I would recommend it 100%. The price is a little steep though

I have a Colt CCU that I love, however the two piece magwell became wobbly...didn't effect function but my OCD couldn't put up with it...In comes the SI magwell..one piece and took 3 minutes to install. The fit is amazing. Hats off to Stan Chen and the SI magwell Thanks
