the 9x18 is a superb piece, of particular note is that it is designed to be kept loaded...safely. the hammer and pin never line up until you pull the trigger, there is a decocking mech that works great, but mainly, its a great piece to leave loaded safely --ammo pops up at fiocci, you have to grab a case or two and you never have to worry, you can get boxes of 50 for about 20.00
Probably just better to shoot .380s through the 9x18. Or install a "jacket" to convert it like they do in Europe, mainly Italy.What would it take to convert a PP Super 9x18 to .380 ACP? My local favorite gun shop still has one for sale.
There are a number of PP Supers for sale right now on Gunsamerica....95% Walther PP Super 9x18s can be had for $500.00 or less. They regularly appear for sale at the auction houses and Gunsamerica. Check them all out. Condition varies. Prices too.
You will not be disappointed.
