What is the most powerful handgun you currently own and do you really enjoy shooting it?

A couple of questions posed recently by “upper Canada“ brought this question to mind. My most powerful handgun is a Savage Super Striker, chambered in .308 Winchester. I thoroughly enjoy shooting it and do so very often. Admittedly, I do not fire it standing freehand very often. I usually use it for IHMSA matches in a modified creedmore position and on a bench rest when testing loads or on a bi-pod when hunting. I’m curious about the big hand gun people have, but even more curious as to if you actually enjoy using them?
