This reverse plug is for the Rock Island 3.5" 1911. It will require minor filing of the top lugs of the reverse plug to fit your slide (shown in alternate image).

Reverse Plugs from EGW are designed for easy installation and increased performance.

Made from carbon steel (not lead alloy) to eliminate cracking, the rounded shoulder is extended for added support with no exposed area where cracks can occur.

A reverse plug is used in comp guns and bull barreled pistols where there is no bushing to retain the spring.

Available in Carbon Steel only. Must be installed by a competent gunsmith.
