Over-Insertion Stop Bushing Kit

PATENT PENDING

First Edition Release - H900 Bronze Heat Treat Finish / 60 sets

Replaces factory grip bushings. Fits most 2011 and 1911 double stack frames 

This redesigned bushing utilizes a precision-engineered tapered face that mates seamlessly with the magazine, creating a mechanical stop that prevents over-insertion and protects the ejector. Custom-fit basepads are no longer required to prevent over-insertion—one magazine will function correctly across most model double stack 1911's regardless of magwell, basepad style or extended magazine 
length. This drop-in solution enhances reliability, minimizes repair costs, and extends service life, making it 
equally valuable for competitive shooters, duty applications, and OEM manufacturers. Additionally, the self centering design ensures the magazine is perfectly aligned with the central bore of the pistol, removing any side to side play, improving feeding and last round lockback reliability. 
With one straightforward innovation, we’ve addressed a long-standing problem with a durable upgrade.

Kit includes 2x O.I.S. Bushings. Grip screws sold separately. Gunsmith installation recommended
