I would say the Jetfire, but for one thing. It does not work or handle like other pistols you may use. It has no extractor, so tap-rack-bang is out. To unload it you do something so unusual that few other pistols require you to do anything of the sort. The peculiar Le Francais pistols, a few other Berettas and a couple of guns from Taurus have tip-up barrels too but by any stretch it's unusual. The Jetfire's mag release is peculiarly sited: Like a Beretta 51, thus not where either Americans or Europeans expect.
So ingrained training with other pistols is unlikely to carry over to the Jetfire, and may even foul you up. It's a wonderful gun because it solves so many design problems brilliantly, but that's the trouble with it, too. I'll vote for the CZ 45 or 92.
