Pin pulled with the lever still depressed means it's a dud?
Is that right? I don't know anything about hand grenades. Real life triumphs over the naivety of people who call themselves artists!
Yeah, pull the pin and the lever expands outwards to depress the internal timed charge to set off the explosive
This gave me a bad shoulder carrying it back from the store - you're not kidding when you say it's heavy!
