Any ideas on how to model something like this??

So something along these lines:

A few shapes to build the upper body part with a Loft:

Then in the side view, one ellipse profile and a path, to make the handle with a sweep:

So now you've got 2 solid pieces that are pushing through each other like this:

Select them and run Construct > Boolean > Union to fuse them together into a single solid. That will create an edge where they intersected each other, select it here:

Then you can run Fillet to round off that edge:

Then it looks like you'd want to do some kind of a sweep to build a curved cutting surface to kind of scallop out the sides, check out the scalloping step in this desert eagle example for something similar:
