If you really need that tip-up barrel,,,
Then you are limited to the Taurus you own,,,
Or several other Beretta mouse-guns that Taurus copies.
There is only one other tip-up barrel gun,,,
The Model 86 Beretta Cheetah.
It is chambered for the .380 cartridge,,,
It is approximately the same size as a Walther PPK or a Bersa Thunder 380.
Unfortunately they are not made any more,,,
And used ones are prized and pricey.
You will easily pay $500.00 and probably more.
