I just test functioned the 9mm 75B SA slide on my P-06 and it cycled 9mm Rem JHP rnds just fine with a 16rd CZ mag and a Mecgar 10rd 40SW mag loaded with 9mm Rem JHP . The CZ mag bodies are the same width just different feed lip widths. Mecgar 9mm and 40 SW mag feed lip openings are the same width and cycle both 9mm and 40 SW rnds. My P-06 has the CGW ring hammer and my P-01 has the CZ angular comp hammer.
