CCO as a carry gun.

[TSOL]

I received my FL CCW about 2 months ago and I'm still toying with what guns work best for me as a CCW. I have been carrying my CZ PCR in 9mm mostly and a S&W J frame 642 when I'm wearing shorts or just running out to the store. I have carried my CBOB several times and like the way it carries and conceals so I'm trying to carry it more than my CZ. while at the same time I'm looking at the CCO but I have a few questions.

1.) Does the CCO really carry that much better than the CBOB?
2.) Is it as easy to conceal without a full bob tail? Or does the grip print easily?
3.) Have any of you found that only having 6 rounds in the CCO vs. the 8 roundss in the CBOB to be an issue?
4.) How well does the Duty Coat hold up to regular holster usage?

Thanks.
