I have been carrying a Post war German PP.PPK/PPKs on and off since the 60's.All have been very reliable.. But in todays market they are running higher than a cat's butt!! I have also had good reliable Interarms/Ranger USA PPK's and on all of the I had the extractors "tweaked" and polished ramps and throats for reliabilty.. Never owned a Bersa but hear good things about them..
