Hello....sorry I can't help you with your question and I hope you don't mind me asking you one....I just picked up a nib PCR myself and want new sights also..can you tell me the parts number on the sights you found, if you don't mind please....
It's difficult finding accessories for CZ's...I'm also looking for a single metal clip inside waist leather holster and no luck there yet either....
Didn't mean to high jack your post , if anything,hopefully this will keep it at the top to get your question answered....
Respectfully, jackpot
