In the smae boat. My research has shown CZ Custom seems to have a slight edge over Cajun Gunworks, but I haven’t seen any objective reason to pick one over the other.
As for the optics, more of the same personal preference over objective rationale to get any particular optic for the CZ. I like how low the RMR and Sig Romeo1 on the slide. The Sig has a rear sight cut into its body, but it has a reputation for being unreliable. That said my RM01 on my M&P CORE has been fairly unrelable as well...
