If you look at a Bersa Thunder it looks just like a PPK... I suspect they, Bersa, copied it... one problem... Just like the Walther, they put a safety on it......
22/45 Fan said:There have been a couple of attempts to make blowback action handguns to fire the 9 mm Luger cartridge but they all pretty much failed due to the power and operating pressure of the round. Smith & Wesson had one notable failure with the SW9 several years ago. The only 9 mm Lugar blowbacks that work are rifle/carbines that use a heavy enough bolt to make the round practical.

The Spanish Astra pistol was a successful blowback design, manufactured in large quantities. It was used by Spain and Germany. It is not, of course, a compact pistol, and has an atrociously heavy slide spring.

Al James said:While not 9mm luger, a CZ52 in 7.62x25 Tokarev is a blow back design as well. They use a system called roller delayed blowback which originated in several MG designs. I have owned a couple and aside from their crudeness they are pretty interesting. Definitely unique! I have always enjoyed shooting the varioius 7.62x25 pistols.

It uses a camming roller system. Not streight blow back.

Gotcha! My post wasn't meant to counter your point as it was accurate and the 52 is a different caliber too. :wink:
I just wanted to mention a different design used to contain a high pressure round in a blowback action.
Between the 2 I would pick the Sig 232. I've owned and used the PPK and PPKs, the 230 and 232 in the past. I much prefer the Sig 232 over the others. And I would much prefer a 9mm over any of them.
