Only put 200 rounds or so through mine (or I should say my wife's) and not a hickup. Got it used for $200.
Single stage, it's nice and crisp - no idea how heavy exactly, but I'd guess at or about 5#. Double stage is kinda long, but smooth. Recoil will result in the underside of your trigger finger getting slapped by the trigger guard.
Eh, it's anemic compared to other things. I've read it's best to use FMJ instead of HP .32acp, simply because of the low velocity and lack of advantage the HP gives you over FMJ. (Do they even make HP .32acp?)
It works almost exactly like a 1911, but smaller, actually. I'm not familiar with Beretta's other firearms, but basically: it's a safety of roughly the same proportions as a 1911, functioning the same way (push down to deactivate) and same tension. Decocking is by lowering the hammer manually while holding it.
It's got like, a 2" barrel if you're counting the chamber - you're not going to get much accuracy out of it. But, it delivers well enough for the range you'd expect to be using it in, ie under 15 feet or so.
Nice feature of the tomcat: the barrel does not actually move when fired, but you can load the chamber in one of two ways: load the magazine and use the slide to strip off a round, or manually load the chamber either before or after inserting the magazine by hitting the 'barrel release' lever (which also doubles for takedown, IIRC - I'd have to look at it again to be 100% certain). This springs the barrel up via spring, with the chamber pointing upwards and the barrel down (provided the pistol is being held in your hand), allowing the insertion of a cartridge. Then just snap the barrel back down into place and it's ready to go. This basically means a weak-handed individual can use it without having to rack the slide.
