How to make Hand Gun Blue print from scratch

Hello everyone im new to Unreal and blueprints and i need to learn how to make my plasma hand gun shoot i got the sound and the meshes but i need a detailed tutorial on how to setup the shooting BP

You could use a weapons class and a sub class for the handgun. The animation starter pack has the animations for a handgun (though you’ll need to blend them in order to get the leg movement for the lower half of the body when your character walks/runs). Otherwise you can just copy the blueprint from any other gun - the only real difference is the animation.

thanks for the info but what i ment is can someone give me a screen shot of how to make my handgun fire projectiles ill add animation later i just cant figure out the bp i tried the others but it wont fire at all
