Destiny Gaheris-D HAKKE Handcannon

I just finished modeling this pistol in Blender 2.82, and I was wondering if I could get some feedback on it. I have attached the .blend file for anyone interested in viewing it. I used normal modeling techniques for the gun itself, and I used a boolean for the top piece. For the smooth look, I used SSharpen with HardOps. My goal of modeling this is practice for modeling hard surface models for games.

Thank you!
