Home Forums Hunting & Shooting Handguns 1911 ....Why is it..

I only use MetalForm in my 1911s, and then only the versions with the standard 7 round capacity and the traditional follower, featuring the nub.

See "nub" illustrated here:



The nub is crucial, and part of the original Browning design, because as the magazine spring wears out, that last round can otherwise start to slip forward of the extractor hook (the nub prevents this by the rim catching on it, preventing forward motion till the slide forces it forward), requiring the hook to snap over it on closure of the action, thus wearing out the hook, eventually causing breakage.
