Boolean help

Trying to make a pistol, I want to make the curve part on the cylinder, see picture.

I’m a little new to this so I was thinking using booleans would be a good idea, I brought in another shape that would ‘impress’ upon the cylinder to give it the deserved shape like in the picture. I don’t know which boolean operation would be good or if it will work at all. Ideas?

great taste in gun choice first of all :smiley: and i would use a meta tube, convert it (alt c) to mesh, the use a difference boolean modifier on the gun, does that make sense :slight_smile:
