I like that it's proportional to its "power"; the slide is very slim, where a lot of more recent 9mms are as thick through the slide as a 1911.
The grip is very well shaped, and is a comfortable reach to the trigger, where a lot of double-stack 9mms are a reach.
The gun was, for many, many years, the most widely used semi-auto service pistol in the world, with much more "street cred" than any 9mm pistol, before or since.
The trigger is pretty good, and can be made pretty great.
In six months or so, it might be one of the guns for which there are lots and lots of double-stack mags still available.
