I just got a Shadow 2 Carry to replace a 320 (XCompact), which is going deep into the crawl space for now, and am thinking about getting an S2O, to replace another 320 (X5 Legion). I originally came here looking for guidance for a misaligned front sight and will post that separately. CZ phone support was nice and unhelpful. Anyway, I live in the Colorado mountains, have 2 shooting ranges right out my front door, and have a lifetime love of ballistics.
