Ok,
Same experince as the OP.... Except I called up CZ parts and ordered the proper slide stop per the website, part number below.
From the CZ website:
"When used on an aluminum-framed compact model (PCR, P-01 and P-06) as well as the steel-framed Compact .40, a specific slide-stop is required for proper last-round hold-open (part number 0440008002, available at no charge through our parts department)."
The slide stop I recieved looked identical to the one included with my Kadet kit and was labeled "kadet 2" in gold lettering..
Can anyone verify if the part number is correct or tell me what the proper part number is?
thank you!
