doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com are these some sort of hammer safeties?

I still think it is an intercepting device to prevent the gun from firing if the sears fail,. When the gun is fired normally the sear is lifted up and the hook clears the pin, if it fails for some reason the hook catches on the pin and prevents the hammer from falling forward.

devrep,
Actually, both prices are ridiculous. Kevin's is crazy high and yours was the steal of the month. If I'd seen the Grand European on the internet,first, I'd have beat you to it!

I have seen those on a Winchester 101 XTR Featherweight (made in Japan) 12 ga. and they are exactly what the OP thought. They prevent the gun from firing when it is upside down. they seem to work on gravity alone and when you flip the gun over and release the sears, the hammers just catch on the hook. If the gun is still apart, give it a try and you will see exactly what I mean. Quite clever and simple but I'm not totally sure about the rationale.
