Hi David S.,
I noticed the asteriks mark on your PPK under the serial #. For what it's worth....Your gun was probably a European police gun and that mark was to remove a police mark/proof. I was told that these marks had to be illegible in order to export the guns to the US. The 69 issue is intersting as well for obvious reasons. 1960's PPK's are amazingly accurate as you found out. Personally, I've never understood why gunwriters go on&on about the Seecamp as an acceptable self-defense gun, but a PPK in the same caliber or .9mm Kurz is unacceptable...go figure!
Its all about shot placement. I have heard of police officers empying entire magazines at perps at less than 10 feet and hitting nothing but a coat tail...........the more you practice, it will come back to you in a time of stress, but if you practice one a month or so, its more instinct and you are less apt to "spazing" out.....TRUE?
