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

    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.
