I had a 645 in the 90s. It was a big honking glorious piece of American stainless steel machinery. Extremely reliable, very accurate, and pretty good ergonomics.
I was quite fond of it because I used it to break up a cocaine fueled drug party that my room mate once invited into my house unbeknownst to me.
Walked in, there were dozens of people I did not know, and they were doing lines of coke and laying all about in various stages of stuppor all over my domicile. Told them to get out. They were unmotivated to listen. One of them ripped my phone out of the wall (this was pre cell phone days), so I had to convince them.
Turns out a big honking glorious piece of American stainless steel machinery is an excellent motivator.
60 seconds later I was standing alone in my apartment.
