The Unofficial P64 Resource Forum

Dear sirs,

I am a researcher at the University of Évora (Portugal) and I am studying the dynamic / recoil behavior in semiautomatic pistols. The physical characteristics of guns, such as slide mass, are fundamental to the mathematical modeling of the recoil. After long internet searches I could not find the information about the mass of the P64 pistol slide. Do you know the value of this parameter?

Thank you very much for your attention.
Best regards,

Maybe someone here with an accurate digital scale could help you.

Have you searched "https://www.google.pl" in the polish language? In Polish this pistol is known as the "Pistolet P-64 (9 mm pistolet wz. 1964)" or "Pistolet P-64 CZAK", and the Slide is the "Zamek". If you search in Polish terms, maybe you will be able to find more data...

Also have you checked the "Andrzej Ciepliński; Ryszard Woźniak Encyklopedia współczesnej broni palnej s. 169" according to that there was a Polish Patent Document No. 54822 for the P-64, maybe the Patent has the data that you are looking for.

I dont have a scale that will weigh the P64 slide, it too heavy for any of my reloading scales.

7.8 oz.

Or, for our friend in Europe, 221 grams.
