I carry a BHP all day, every day. I have many holsters for mine... you just kind of accumulate them over time. The most frequently used is a COM holster by HBE Leatherworks. It's old, beat up, abused, and worn, but still comfortable as ever.
Cocked and locked isn't even a slight concern. I've never had the safety swipe off, but even if I did, it's still in a holster that covers the trigger. Absolutely nothing to worry about.
