Hi, As a newbie forgive my lack of knowledge, but are there any good pistols out there in .380 that would make a good host for a silencer? I can think of a few but where does one get a threaded/extended barrel for say a PPK or the like? I like the 380 cuz all of its ammo is subsonic, unlike 9mm, barring spendier & sometimes hard to find 147 grain. thanks

I asked this a little while ago and the consensus was that there are very few .380 guns to suppress due to the way most of them function.

I would think there are some fixed barrel 380s that would be perfect for suppression

The .380 is a poor choice for a number of reasons related to the action. First off, all the .380 barrels are fixed, which is good. Second, all the .380s are simple blowback weapons, which is bad.

The suppressor will increase bore pressure a bit, resulting in faster opening of the action (allowing more gas/noise to escape through the ejection port). In addition, the faster slide velocity makes the weapon cycle faster, and the magazine spring too often does not get the next cartridge in position for feeding in time. This results in a stovepipe jam.

Since you are considering .380, terminal ballistics does not seem to be that much of an issue. In this case, I would suggest .22LR for a first suppressor. It is significantly smaller, lighter, cheaper, and has better performance (having to deal with less gas). It is also more fun and seriously more economical shooting.

Not to mention, where I live 9mm 147-gr ammo is typically cheaper than .380.

I have a PPK and Makarov - both in .380 . The problem is blowback from the ejection port , which is increased by back-pressure caused by the suppressor ... To be effective , you would need something that uses the Browning tilt-barrel action , like the Colt Mustang , .380 Government , or similiar locked-breech action ... As others suggest , .22 or 9mm might be less of a headache to suppress ...

True, but it is possible to delay action opening by machining a shallow ring in the chamber. Makes easier for the forensic folks to identify the brass left at the crime scene.
