I have the CZC plate system on my SP-01 shadow. I got it for my Razor red dot which turned out to be a poor choice for a slide mounted dot. Super glad I got the plate system as I now use an SRO. Their plates are keyed into the slide, screwed down and the extractor pin goes through it. No chance for movement.
Only problems I had with it were self inflicted. I didn't loctite the first dot and it came loose and chewed up the bosses on the plate. CZC was good enough to send me a new plate while I was waiting for VTX to send me a new dot. Long story short, after my 6th RZR I decided to go with SRO but CZC was out of rmr plates and I needed it before nationals so I had a local machinist remove what was left of the bosses from that first plate and put in steel bosses and tap holes for the SRO. 5-6000 rnds and no sign of letting up.
Plate system doesn't leave you married to a sight. There will always be something better.
