The ReCover Tactical Grip and Rail Systems have proven to be the most stable rail solutions on the market as well as the most popular, and are easily installed on your gun in under 3 minutes. The high-grade, lightweight, glass reinforced polymer ReCover can be installed without the need for a gunsmith, and requires no permanent modifications to be made to your firearm. The CC3C for the COMPACT OFFICER'S sized 1911 is the most stable rail mount on the market and the added benefit of a 1911 grip that enhances the look of your firearm. The Recover CC3C Grip and Rail System will NOT fit on FULL SIZE 1911's (if your pistol uses a 8 round magazine then it is a FULL SIZE 1911 and the CC3C is not compatible), do not purchase this product if you have a FULL SIZE 1911. Full size 1911 owners need to purchase the CC3H or CC3P which are also available here on Amazon. If unsure about your grip size please use the graphic image above to measure the grips in order to ensure fit.
