If CZ made the cut at the factory, I'm sure it wouldn't cost much extra. As prices of RDS drop, especially if the factory includes the cut, I just think this will become a really popular set up. I mean, people are paying $100-$150 now just for upgraded sights, so IF the gun cost $200 more with an RDS, I think it would be a winner. JMHO
Burris or Vortex are good durable optics and about $200 now (on sale) and I believe they both fit the same mount pattern. Leupold and RMR are great Optics, but considerably more $$ and each are different mounting patterns.
So, my vote would be a CZ P-07 and/or P-09 cut for Viper optic with sights that will co-witness. Buyer would then have the option to mount a Burris, Vortex Viper or Venom. Same mount.(I think).
However, I'm just not sure if there's enough room on a P-07/P-09 slide for both Viper cut and a rear sight. Might take CZ a little extra thought.
Meanwhile.....there's good machine shops.
