I agree with your thoughts on the BP9CC. I've said it many times...if Lay-z-boy chairs ever made a trigger, it would be on the BP9CC. I have never shot a striker fired pistol with a nicer trigger. Even pressure, clean break and a better reset. It is also a natural point and shoot gun for me. In defensive reaction drills, I'm very accurate without aiming down the sights. As for CC, It's one of the slimmest at .94", all edges are rounded to prevent snags, the mag release is stiff to reduce accidental release and I can fit my pinky.
Only downside for me is the mag release/trigger disconnect. It can have fte/ftl issues if limp-wristed (wife) but I always push into my shots and it's only done to me when I demonstrate to my wife on "how not to shoot".
I recently switched to a PPS M2 as it seems to be a natural extension of my hand, especially in close, defensive drills but I still love the BP9CC.
Looks like the factory designated repair center is Colorado Gun Works in Lyons, IN, so that might be a plus if you ever need work done.
I like my S&W 3906 it may be built like a tank and a little big for IWB but it is dead nutz accurate.
The two things you listed are exactly why it was not included in my list to check out (which was big). It is a good solid gun don't get me wrong, much love, but doesn't fit in the category I was looking to fill.
God write up. Even though I am a shield owner and really like mine, I'm glad to see people aren't just blindly following the groupthink found on the forums. There are good firearms out there other than the ones people tend to flock to.
Hadn't been back on in a long time...but well over 2,000 rounds and trust the thing with my life.
I'm between a BP9CC and an honor guard...
