Mine is actually the Hungarian model PA-63 which is a much closer copy of the Walther PP. But all the various Maks are essentially PP copies. I used mine when I did the original handloading data for the American Rifleman back in 1991. It ate 3,000 rounds of handloads (some too hot to print) for that article alone; and has gone to two handgun shooting schools, where it digested several thousand more. It sits in a holster in my truck right this second as my vehicle carry gun. In all that time, it has never failed to feed, fire or eject. 100% perfect. I also had two shooting instructors try to buy it because it's so slim, light and above all - accurate.
Sounds like I like 'em, huh?
