If you're open to the idea of an autoloader and you want a pure target pistol, look around for a Walther GSP Model in 32Long.
There are a couple of different versions but they all chamber the 32Long W/C ammo. There is also a 22rf version which is probably more common.

Made to do one thing and that is shoot target competition. Prices run $1600 and up from what I've seen,,,usually up!.

Dealer Joe Salter has an all factory 22 w/32 conversion that is pending sale that was priced at $2150.

Also,,Clark made some conversions on the Ruger 22 Target Pistol to 32 S&W Long years back.
A very long shot chance that you could find one of those around. I have no idea what they may be priced at now.

For the more traditionalist (like me), if I absolutely had to have a .32,,I'd either go and find an original K-32 or convert a K-38 to .32 .
On a conversion,,I'd cut the barrel to 5",,just because it'd look right!


Good luck in your search!
