Historically interesting-there are a bunch to pick from. I like the walther PP as it has a lot of history both as a police tool and as a military issue sidearm. Prewar or wartime pistols are not cheap, postwar West Germany and French pistols are more affordable. The old colts are pretty slick too, but pricey.
Shooters- Can’t really beat the PP or the Beretta 81. Both are plenty accurate, are big enough to grip comfortably, and are heavy enough to absorb recoil making for a fun day at the range. Berettas are selling at a discount now since surplus pistols have recently been imported.
Carry- there’s not a whole lot of good options. Keltec is probably the best option that’s easily available. Taurus TCP32 was a thing but it didn’t get a whole lot of units made before it was stopped. I think the Ruger LCP May have had a few made as well. The issue with most 32 pocket guns is that they are either poorly made (Jennings, Lorcin), are hard to find (tcp, lcp) are built into a .380 frame as an afterthought, or are so small that they are hard to shoot but they still weigh a ton. The Keltec is a clear winner as a carry gun. Put it on a necklace, put it in your shirt pocket....
