Is this a proven fact, or is it just sales hype? Do you know of anyone who has ever put it to the test?
MIKE GEORGE says:
There is no reason why an extra bent on a gun’s tumbler should not prevent an accidental discharge if a gun is dropped, providing the blow is not so severe as to lift the sear very high.
Such accidents are rare anyway, and I have never met anyone who has suffered such a misfortune.
One point to remember is on the majority of shotguns the fact the safety is ‘on’ would not prevent an accidental discharge should the gun be dropped.
Most safeties merely disengage the trigger from the rest of the firing mechanism, leaving the action still cocked and the hammer free to fall should the sear become disengaged for any reason.
Intercepting safety sears are usually only found on better quality guns.
