I bought a pair of Austrian police surplus PP pistols in excellent condition back when they were being imported at very nice prices. Since then I've also added a few FEG PP and PPK/S style pistols.
As noted above, handloading .32 ACP has its share of challenges.
1) European brass tends to be thicker walled to accommodate .308-309 diameter bullets, while US brass tends to be thinner walled to accommodate .310-311 sized bullets. It all works well until you seat a .311 sized US bullet in a European case and find it won't fit in a tight .32 ACP/7.65 Browning chamber.
So you either sort your brass, or you use a post sizing die to ensure the final round is sized back to the required diameter.
2) The case and the powder charges are small, so you end up having to use an extra small charge bar, or a drum style measure with a very small cylinder diameter.
3) the combination of small bullets, varying case wall dimensions and comparatively thin case walls in general, requires attention to detail and some finess when assembling the round.
