The same great features of the SI Magwell, now in a Compact edition. 2 models are available to fit most compact 1911s:

1. Colt/Kimber/Springfield. Fits Colt Defenders, Colt Officers, Kimber Ultra, and Springfield Compacts. Does not fit Springfield EMP.

2. Dan Wesson- DWs have a slightly different mainspring housing pin location; this model is made to specifically fit Dan Wesson pistols.


If you are wondering if the Compact SI Magwell will fit your specific pistol, please refer to our FAQ at the bottom of this page.

Large sculpted funnel for dramatically faster reloads. Through careful CAD design, every last millimeter of available real estate was turned into reload-enhancing

    Amazing fit

    Posted by Jeffry Queen on 12th Sep 2023

    I wanted to expand the grip on my Kimber Ultra Carry II because it was a little bit short. The Chen Custom SI magwell is the perfect solution! I added a set of VZ compact magwell grips and its like my Kimber was custom made for my hand. Incredible product that fit perfectly and did not require any additional blending.

    Great product that dropped right in and fit great! The magwell contour is a great fit to the standard thickness and profile available from VZ Grips.

    I am 1000% pleased. I love this magwell! It is absolutely perfect!! So easy to install thanks to the video and instructions. Installed it on a Colt Gold Cup 9mm. Can’t wait to get the VZ grips that I ordered to complete the look.
