Grenade explodes on character who fires it

Hi.
Im fiddeling for too long on this. i tried spawning the grenade from an offset, i tried to add the characters velocity and i tried a delay before the collision is enabled but i cant get good results. has anybody an idea how to solve this?
ps: maybe enable the collsision from the grenade when it leaves the character boundings?

edit: it is launched by a grenade launcher with a decent speed and does not always explode. only when walking forward.

simple add a variable with the type of your character to your grenade and set “Instance Editable” and “Expose on Spawn” enable for it.

now go to your character and when you spawn grenade it will ask you that variable so you can set it “Self Reference”

now you know who fire that grenade when you need it

thanks for the advice, but i already have done that.
after more experimenting i will stick to a short delay before the collision becomes enabled.
