Sharps
I had an Astra 600 as one of my first semi-autos. Ugly? Well let's just say it was ruggedly handsome, but visually challenged in a rather functional way. Kind of like the girl on a blind date who was best described to you as "having a great personality".
And while it was incredibly accurate and super reliable, I would never consider it a fun range gun. After 100 or so rounds it just became too painful to continue shooting it. The web of my shooting hand would hurt for days afterwards and it would take nearly a week before I was able to shoot again. So the Astra 600 to me was a good gun but not necessarily a good gun design.
