Shadow, both guns are NOT DAO or Double Action Only. The Bersa Thunder .380 (of which I own one) has the ability to fire the first round as Double Action where you squeeze back on the trigger and it in turns cocks and releases the hammer. ALL subsequent shots are then single action as the hammer is in the cocked position, unless you "decock" it with the decocking/safety lever.
The Bersa is quite safe to carry with one in the chamber. There is a firing pin block that prevents the forward movement of the firing pin, unless the trigger is in the rearward position. It is also the same on my Taurus 24/7 Pro pistol. There is a plunger that is moved only with the rearward application of the trigger. Then, and only then (barring any mechanical failures) would the firing pin be able to travel forward enough to strike the primer.
You can fire the Bersa .380 entirely single action as well. Simply cock the hammer back even with the first round in the chamber, then squeeze the trigger in single action mode. However, in a combat scenario, it is quicker and safer just to squeeze back on the long trigger pull it takes to cock and release the hammer.
