I've been trying to model a sawed-off shotgun and have run into a wall on how to model the handle. The general shape isn't too much of an issue as I just extruded a plane based off of a reference image (the second image), but there are sections that I don't know how to model.

For instance, the handle transitions from a circular base to a more squared-off shape. Also, on the sides there is a raised, triangular portion that I've found is tricky to model.

Any advice on how to go about modeling this would be greatly appreciated.

Reference Images: The circled portion is an issue area, especially the transition from triangular point to the handle.

The base of the handle starts circular, but when it attaches to the barrel portion it is square.

What I've tried so far: I feel I have the general shape, just missing the difficult to model portions.

I'm lazy, so I'd let Blender do most of the job.
Make the rectangular part and the round part, and let Blender make the transition for you.

Project blend file for your inspiration:

01) Square part
- Start with a basic cube, add loopcuts, extrude it and stuff...
- Use proportional editing (I used Sharp profile)
- Use subsurf modifier

Use proportional editing for those tapered edges enter image description here

02) Round part
- I used a basic cylinder and extruded it.
- Just make sure the number of vertices (and edges) is the same as in the open loop of the square part.
It's 24 vertices (and edges) in this case.

03) Bridge Edge loops
- Select and bridge the two edge loops (Edge > Bridge Edge Loops)
- Both loops need to have the same number of vertices
- Both meshes need to be in one object (you can join them into one with Ctrl+J)
