What brand/model of .22lr auto pistol with 8--10 in barrel is good?

Looking for a .22lr pistol.  I have seen some with a long barrel.  Which company makes these?  Are there aftermarket barrels that can be swapped out with the stock barrel?

The Ruger mkII, mkIII, 22/45, etc all can be mod'd out with upgrades, barrels, triggers, etc  just like a 10/22. I know the Browning Buckmarks are pretty popular too.

Ruger 22 Charger - 10"
Ruger Model Single Six Convertable - 9.5"
Smith and Wesson Model 41 - 7"
Browning - 7.5"
Rossi Matched Pair Pistol - 11"

There are more with shorter than 7" barrels, but I don't know if any of them have aftermarket barrels.
